Field Introduction This study was inaugurated primarily to identify one of the more destructive pests of banana in Central America and northern South America. During times of large populations, this pest as a caterpillar feeding upon the leaves of banana plants can so reduce the leaf surface and shorten the leaf life that fruit weight and size are consider- ably reduced (Harrison, 1959). Upon taking up the task of identifying this species, the author quickly ascertained that many misidentifications were cur- rent both in the literature and in the various col- lections placed at his disposal. Through the years this ctenuchid moth has been identified as Cerami- dia musicola Cockerell (1910), as Ceramidia butleri (Moschler) (Cockle, 1904; Zerny, 1912; Harrison, 1959; Ostmark, 1974), and as Ceramidia viridis (Druce) (Cevallos, 1957). The correct name for this species is Antichloris viridis Druce, as will be shown later. As usually happens in any study of, or attempted identification of, species in a group of moths upon which little careful work has been done and upon which a great deal of careless attention has been William D. Field, Department of Entomology, National Mu- seum of Natural History, Smithsonian Institution, Washing- ton, D.C. 20560. lavished, this examination soon enlarged to a re- view of all of the species that had been originally described in Ceramidia Butler or that had been later placed in Ceramidia. It extended to a study of species in other closely related genera in order to carefully and accurately define Ceramidia and its species and their closest relatives. An examination of the literature revealed that up to the present time, some 34 species were thought at one time or another to belong to Ceramidia. This study first, because of newly dis- covered synonymy, reduced the number of valid species involved to 24 species and second, because of the resulting redefinition of the genera Cera- midia, Ceramidiodes Hampson, and Antichloris Hiibner, reduced the number of species assigned to Ceramidia to 2 species, recognized as valid the single species and its genus Ceramidiodes, and increased the number of species assigned to Anti- chloris by 17 species. Among the latter is the ba- nana pest, which was responsible for starting this study. In addition, two former Ceramidia species were found to belong to Amycles Herrich-Schaffer and two were found to belong to Eriphioides Kirby. The scope of this paper is the treatment of the genera Ceramidia, sensu stricto, and Ceramidiodes and the Caca species group of Antichloris, where SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY the banana feeding pest A. viridis belongs. The correct generic assignments of 19 former species of Ceramidia and several synonyms of a few of these species are given in the annotated list at the end of this paper. The type-specimens of all species have been studied (and most of these are illustrated herein) for habitus and other characters and have been dissected for a study of the male and female genitalia. The genitalia and habitus, as often in studies of Lepidoptera, again proved to show the strongest generic and specific characters. ACKNOWLEDGMENTS.?I thank Dr. Francisco Fer- nandez Yepez of the Central University of Vene- zuela in Maracay, Dr. H. Eugene Ostmark of the Division of Tropical Research, Tela Railroad Company, La Lima, Honduras, and Dr. Louis M. Roth, formerly of the Department of Research, United Fruit Company, Norwood, Massachusetts, and now of the United States Army Natick Lab- oratories, Natick, Massachussets, for study material. I especially thank the last two gentlemen for prod- ding me into making this study in the first place. I am especially grateful to Mr. Allan Watson of the British Museum (Natural History) for the loan of a great amount of material and for numerous photographs of type-specimens under his care, without which I could not have made this study. I greatly appreciate the courtesy shown to me by Dr. F ederick H. Rindge during my study at the American Museum of Natural History and for the loan of material in his charge. I am especially thankful for the loan of two Moschler types made to me by Dr. H. J. Hannemann of the Zoological Museum of the Humboldt-University of Berlin. For the loan of a Zerny type, I am similarity thank- ful to Drs. F. Kasy and Richard Imb of the Zoo- logical Collection of the Natural History Museum in Vienna. Mr. Robert Dietz, in the course of bor- rowing material from Dr. Walter Forster of the Zoological Collection of the Bavarian States, Mu- nich, Germany, for his own study, secured the loan of a type that I needed for study and I thank both of these gentlemen for their cooperation. I also wish to acknowledge the assistance of Mrs. Vera Milbank, Museum Technician, for biblio- graphic aid. Mrs. Elsie Froeschner of our staff of professional artists prepared most of the drawings of the male and female genitalia (Figures 75-100) and, after her recent retirement, Mr. Lawrence M. Druckenbrod prepared the remainder (Figures 101-105). Mr. Victor E. Krantz of the Smithsonian Institution photo laboratory made many of the photographs. Natural History Ctenuchid moths are day fliers and therefore readily and easily observed in the field; in addition many are heavy bodied and are relatively slow fliers. In spite of this, there is no recorded informa- tion concerning disperal (except that Antichloris viridis moths can fly as far as a kilometer or more from their emergence site), mate selection, court- ship behavior, or even the time of adult activity (except that adults are active during the daylight hours). Nothing is known about the food plants, the life history, or life habits of the species of Ceramidia, Ceramidiodes, and of the vast majority of Antichloris species. Fortunately and only because of its economic destructiveness, the life history of Antichloris vir- idis Druce has been described at some length by both M. A. Cevallos (1957, under the name Cer- amidia viridis) and by James O. Harrison (1959, under the name Ceramidia butleri). FOOD PLANTS.?The only known food plant of Antichloris viridis is banana, Musa saepientum Linnaeus, and I suspect that Antichloris caca also feeds upon this plant. A third species, Antichloris eriphia (Fabricius), is known to feed upon banana (see: d'Araujo e Silva, et al., 1968:219; Ostmark, 1974:163). The related Amycles dolosus (Walker) of Brazil has also been reported feeding upon banana (Bondar, 1938). Jan Sepp (1848:145-146, pi. 69) illustrates a larva of Antichloris eriphia (under his name Sesia melanochloros) feeding upon the underside of the leaf of a species of Canna (Cannaceae), which he calls by the name "Taye Indien au Surinam." He also states that he has seen this caterpillar feeding upon the leaves of "Jurca-bessies" but that he does not know the Latin name of either of these two plants. His illustration (1848, pi. 69) definitely shows a flower stalk and leaves of Canna, according to a personal communication from Dr. Lyman B. Smith, Department of Botany, National Museum of Natural History. The plant "Jurca-bessies" re- mains unidentified. Although A. eriphia belongs to a different species group, it is possible that A. NUMBER 198 viridis and other species of Antichloris have Canna as their endemic host plant. Banana is thought by almost all botanists who have studied the problem to have been introduced into the New World probably not before 1516, when one clone was taken from the Canary Islands to Hispaniola (Haiti). This was perhaps the first of many separate introductions into the Caribbean and to Central and South America where most of the world bananas are now raised for export. Spe- cies of the moth genus Antichloris are solely New World species occurring only in Central and South America except for A. quadricolor Walker and A. dementi Schaus from Jamaica and Cuba, respec- tively. These last two species are not known to feed upon banana. It is certain that A. eriphia expanded its choice of food plant from Canna to banana as the latter became available, and it is probable that A. viridis did likewise. Interested workers who wish to control the ravages of these ctenuchid banana pests would do well to look for these pests upon Canna and perhaps other plants on or near banana plantations. ADULT.?The moths of Antichloris viridis are very active and may often be seen flying in open sunny areas. They fly long distances and if helped by the wind can reach a kilometer or more from their emergence site (Cevallos, 1957). According to Harrison (1959) they are short lived in the laboratory, living for from three to six days. He ascribes this to lack of proper food, because it apparently wasn't until after completion of his laboratory rearings that he observed adults in the field feeding upon the nectar of the blossoms of orange and lemon trees. The adults require only a few minutes after eclosion from the pupa to emerge from their cocoons. They immediately, as do all winged Lepidoptera, climb to a convenient place where they remain still until their wings ex- pand and dry. This process usually takes about an hour or slightly more, after which they are ready and capable of flight. The males of all Antichloris species and of Ceramidia and Cermidiodes have an eversible gland on the ventral surface of the abdomen between the seventh and eighth segments in front of the geni- talia. This gland takes the form of hair pencils that arise from a large bilobed pocket, which can be forcibly extruded. In addition both sexes of A. viridis have a slightly retractable area covered with red scales on the prothorax behind the head. This structure has been responsible for overnaming in this species, separate specific names having been given to specimens with red scales exposed and to specimens with red scales hidden because of this pouchlike process being in the retracted position. 1 suspect that both this prothoracic pouch and the abdominal eversible glands of the male have great influence upon mate selection and mating; how- ever, no information concerning these types of activity has been recorded for these species. Mating takes place after the adults are about two days old (Cevallos, 1957). OVIPOSITION.?Eggs are laid singly or in groups of from two to four, sometimes in a line or some- times in a mass on the undersides of mature young leaves of the food plant. According to Harrison (1959), his laboratory-reared females usually began oviposition on the second or third day after emer- gence. Not more than 10 eggs were deposited by any single female in the laboratory; however, under normal conditions in the field the female can prob- ably deposit upward of 30 eggs. T H E EGG.?The egg is described by Harrison (1959) as "subglobose, greenish in color, and averages 0.81 mm. in diameter." The egg stage lasts five or six days and about 24 hours before hatching, the egg changes from green to almost transparent milk-white color through which the reddish-brown mandibles of the larva can be seen. THE LARVA.?It takes the larva about 12 hours or more to eat its way through the eggshell, where- upon it soon begins to eat the remainder of the shell, this taking from four and one-half hours to six hours. Next it begins feeding upon the leaf near where the egg had been attached. This is on the underside of the leaf, where, because of the small size of its mouthparts during the first three instars, it only eats partway through the leaf. Later the larva, when larger, eats completely through the leaf. In the field and upon small potted plants in the laboratory, its existence is entirely spent on the undersurface of the leaf. When reared in petri dishes in the laboratory, it showed no preference for the lower surface of pieces of banana leaves. In feeding, the larva moves gradually backward and parallel to the small veins, and according to Harrison (1959) it leaves holes as large as three and one-half inches long and one-half inch in width. After each molt and at the beginning of SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY each successive instar, the larva completely con- sumes its own exuviae before feeding on the leaf again. The larva molts five or six times, undergoing six or seven instars. Harrison (1959) reports that 90 percent of the larvae he raised passed through seven instars and 10 percent through only six in- stars. The duration of the first instar was from two to four days, that of the second through sixth in- stars was only two to three days each unless the sixth instar was its last before pupation, in which case this instar fed for from four to six days, as does the seventh instar for those larvae that went through a seventh instar before pupating. As would be expected, the last instar consumed more food than the total of all the other instars. The fully grown larva has a yellow head with a white body that is nearly iridescent and slightly pink with small lateral red spots and is covered by abundant creamy white and long silky hairs, which arise from verrucae. Cevallos (1957) reports that these hairs are urticating, and caused a sharp pain and a rash when they came in contact with his skin. THE PUPA.?Pupation takes place in the shade of leaves upon which the larvae fed or behind the leaf sheaths on the side of the pseudostem. Some larvae also pupate under the curling and drying tips of older leaves and some pupate on the stalks of the fruit and between the fruit, as is evidenced by numerous records of this moth being taken from banana stalks in ports of entry all over the world where bananas are imported. Mostly from its own hairs and silk, the larva forms a weak and very thin cocoon that is whitish yellow in color. The naked pupa is cocoa colored and measures about 15 mm. In Ecuador, according to Cevallos (1957), the pupal life lasted from 6 to 10 days, while in Costa Rica, according to Harrison (1959), this pupal life was from about 8 to 10 days and for one individual was 16 days (dry environment?). LONGEVITY.?In Ecuador the whole life cycle takes place during the winter season and lasts about six weeks. There may be as many as three generations of larvae during this season (Cevallos, 1957). In Costa Rica this ctenuchid reproduced throughout the year and in the laboratory, accord- ing to Harrison (1963), the egg stage lasts from 5 to 6 days, the larval stage of from six or sometimes seven instars lasts from 16 to 26 days, the pupal stage may be as short as 6 days (Cevallos, 1957) but normally lasts from 8 to 10 days; however, in one instance (as reported above) it lasted 16 days (Harrison, 1959). PARASITES.?The thorough observations of James O. Harrison (1963) in Costa Rica are the source of most of the recorded information on the parasites of the egg, larva, and pupa of A. viridis (recorded by him under the name Ceramidia butleri). He reports that all stages of this species are attacked by natural enemies, which become more noticeable during periods of high host populations. Cevallos (1957) states that in Ecuador the larval and pupal stages of A. viridis are so heavily parasitized by other insects and fungus that by the end of the rainy season the population of this host is deci- mated by about 90 percent, too late, however, to be of help to the banana growers, as the ctenuchid has already done its damage by this time. In Costa Rica the only known parasite to attack the eggs of A. viridis is Trichogramma minutum Riley (Hymenoptera: Trichogrammatidae, recorded under the name of its junior synonym, T. pretiosum Riley, Harrison, 1959). Harrison states that this parasite often parasitized these eggs and that of 763 eggs collected at Goto, Costa Rica, in the sum- mer of 1959, 51 percent were parasitized. These eggs turn black 24 to 48 hours before the emer- gence of these tiny wasps. The larvae are parasitized by a number of Hymenoptera and by one Diptera. The latter, Achaetoneura aletia Riley (Diptera:Tachinidae), was the most abundant parasite on this ctenuchid larva in Costa Rica. A braconid, Meteorus laphyg- mae Vierick, is a widespread parasite of A. viridis and during November of 1960, 20 percent or more of these larvae collected each month were para- sitized by this insect. Two other braconids, Apan- teles sp., and Macrocentrus sp., near koebelei Vierick, and an ichneumonid, Carinodes sp., have been reared from larvae of A. viridis. Dr. Z. Boucek (1962) described and recorded Elachertus cerami- diae (under the name Stenomesius ceramidae, Hymenoptera: Eulophidae) as a parasite of larvae of A. viridis in Ecuador. The same year, the range of this parasite was noted to include larvae of this host in Panama, Costa Rica, and Honduras (Burks, 1962). Harrison (1965) states that it is an impor- tant parasite of A. viridis in Central America. His observations showed that the adult females of this NUMBER 198 parasite were often observed on caterpillars in the held, with as many as eight on a single caterpillar, and that most of them had their ovipositors inserted into the cuticle of the host. With the increase of the parasite population, the caterpillar population rapidly decreased, so that starting on 27 June there were 5.8 caterpillars per banana leaf, with about 43 percent of these parasitized by a maximum of 40 parasites (eggs and larvae) on each caterpillar. By 3 August there were 1.7 caterpillars per leaf, with 90 percent of these parasitized by a maximum of 118 parasites for each caterpillar and by 6 Sep- tember there remained only 0.5 caterpillars per leaf, with no parasites observed. Burks (1960) gave a number of records of Brachymeria comitator (Walker) (Hymenoptera: Chalcidae) reared from pupae of A. viridis in quarantine in the United States and from pupae originating in Mexico and Central America. It is uncertain whether or not a parasite directly attacks the pupal stage, according to Harrison (1963), but there are two parasites that emerge from pupae of the hosts in Costa Rica. These are this same chalcid mentioned above, Brachymeria comitator (Walker) and Carinodes sp. (Hymenop- tera: Ichneumonidae). The chalcid acted also as a secondary parasite since six pupae of Achaeton- eura aletiae (Riley) (Diptera: Tachinidae), which had emerged from larvae of A. viridis, were them- selves victims. In one area near Coto, Costa Rica (Harrison, 1963), a large percentage of the host ctenuchid were attacked by two species of fungi, one being Entomophthora sp. and the other an unidentified species. Parasites of the adult ctenuchid are unknown. PREDATERS.?Three spiders, Thiodina pseustes Chamberlin and Ive, Eriophora edax Blackwall, and Eustala fuscovittata Keyserling, and one small lizard (unidentified) have been observed feeding upon small larvae of A. viridis. Birds have not been observed attacking either the adult moths or the larvae; however, these larvae with their habit of feeding and resting on the undersides of the leaves are probably not easily observed by birds. There has been only one observation reported which would indicate predators of the adult stage of this ctenuchid moth?the one by Harrison that he has occasionally seen adults entangled in the webs of the orb-weaving spider, Gasteracantha cancriformis (Linnaeus). MIMICRY.?Forbes (1960:56) and others state that many species of the family Ctenuchidae are mimics, mostly of Hymenoptera. Schrottky (1907) mentions Ceramidia as a mimic of Hymenoptera. While this conclusion could be drawn from a super- ficial examination of Ceramidia and Antichloris species and relatives because of their narrow fus- cous or black wings, one must not forget that black and fuscous are common basic colors in many groups of insects. Certainly the abdomens of these moths with their relatively wide bases, which ap- pear even wider because of the firm attachment of their thoracic tympanic hoods to their basal abdom- inal segments, do not seem to resemble the abdo- mens of the majority of wasps. No one has as yet suggested exact models among the wasps for Anti- chloris and Ceramidia species. Careful observa- tions in the field might confirm this presumed mimicry and Antichloris viridis, because of its frequent large populations over a large geograph- ical area, would be a likely candidate to observe. Geographical Distribution The genera Ceramidia, Ceramidiodes, and Anti- chloris are restricted to the tropical regions of the New World. The genus Ceramidia with two species is found over a great part of tropical America from Venezuela and Trinidad east into French Guiana and south through a large part of Brazil, Colombia, Ecuador, Peru, and Bolivia. Ceramidiodes with a single species is widely distributed in humid, low- land, tropical Brazil but apparently does not range outside of that country. Antichloris is a genus of 27 known species that I divide into three species groups: (1) the Quadri- color species group with two species that occur only in Jamaica and Cuba; (2) the Caca species group (the only group of this genus that I am attempting to treat thoroughly in this paper), with two widely spread species that have a combined distribution ranging from Mexico south throughout Central America and over most of the northern half of South America as far as Colombia, Ecuador, and Brazil; and (3) the Eriphia species group with 23 species that range collectively over much of the same general area as the Caca species group and SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY even farther south through Peru and Bolivia into Argentina. In the Eriphia species group only two species, A. eriphia and A. chloroplegia, have broad distri- butions, A. eriphia being found from Venezuela into Trinidad and French Guiana south through Colombia, Ecuador, Peru, and Brazil into northern Argentina and A. chloroplegia more or less rang- ing in the same general area as far south as Peru and Brazil. Twenty-one of the 23 species in this group are at present known only from one or two localities in a single country or sometimes from only a single locality in each of two separate countries. Five of these 21 species are found only in Venezu- ela, four are found only in Brazil, three each are found in Ecuador and Costa Rica, two separate Key to the Genera and Species Treated in This Paper 1.

One species is found in both Ecuador and Peru and one species is found in both Ecuador and Bolivia. I believe that one should not form any general conclusions about the place of origin, area of diversity, and dispersal for the genus Antichloris at present because much more collecting and much more study is necessary for those 21 species that have such an apparently limited distribution. Are they really this limited in distribution? A number of these species are still known only from their original type-series. One should not at present draw the conclusion, for example, that because there are five species known to be exclusively en- demic to Venezuela and two additional species more broadly ranging but abundantly present there, that Venezuela is the primary area of diversity and dispersal. Many of these Antichloris species of all three species groups seem to prefer the hot, humid low- lands, but others are found at higher elevations ranging up to 2000 meters. Classification Ceramidia, Ceramidiodes, Antichloris, Amycles Herrich-Schaffer, and Eriphioides Kirby represent five genera in the Ctenuchidae that form a branch of closely related genera, which Hampson (1898: table facing page 22) in his phylogenetic tree shows diverging from Sciopsyche Butler. I have found no reasons to alter this concept and in fact believe that these five genera will probably be considered to form a tribe or subtribe within the subfamily Euchromiinae when that subfamily is subdivided. These five genera have many characters in com- mon, especially in the male and female genitalia. In the males all have a deeply divided uncus that forms two long entirely separate arms, a broad and relatively short and downwardly bent aedeagus, a sturdy saccus supporting the valvae, and a very similar and peculiarly shaped anellus supporting the aedeagus. Antichloris, Ceramidia, and Cerami- diodes have a pseuduncal lobe in front of each uncal arm; these lobes are shorter than the uncal arms and arise from the tegumen. All of these genera except Ceramidia have a soft hairy sub- apical lobe on the outer side of each valva. Char- acters for separating these genera were found mainly in the shape and armature of the valvae and in the female genitalia in the shape of the anterior genital plates, in the position of or pres- ence or absence of cupules for receiving the clasping organ of the male, and in the internal elements of the ductus bursae and bursa copulatrix.

Ceramidia is restricted here to the species C. fumipennis (Walker) and C. phemonoides (Mosch- ler). Nineteen species formerly placed in Ceramidia are transferred to other genera (see list at end of paper). In habitus this genus is easily distinguished from the related genera Antichloris and Ceram- idiodes by the color pattern of the underside of the abdomen and by characters in the male and female genitalia. In Ceramidia the underside of the abdo- men has a broad, median fuscous band running from its base through the seventh sternum, with a white band along each side of this fuscous band (Figures 2, 4, 6, 24). In the valva of the male gen- italia (Figures 75, 76) this genus lacks the pulvi- nus found in Ceramidiodes (Figure 77) and the subapical fleshy lobe found in Ceramidiodes and Antichloris (Figures 78-82, 92-102). In the female genitalia (Figure 84) the anterior genital plate is entirely different from those found in Ceramidiodes (Figure 85) and Antichloris (Figures 86, 87, 89). Male genitalia (Figures 75, 76) with uncus com- pletely divided, forming two long, entirely separate arms, each semispatulate at tip. Behind each of these arms is a pseuduncus lobe arising from tegu- men, these lobes much shorter than the uncal arms. Saccus in ventral view broad posteriorly, sharply 8 SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY and suddenly narrowed and greatly projected an- teriorly, so that it is about as long as broad or longer. Center of posterior margin of saccus dis- tinctly convex. Aedeagus long and slightly down- ward curved in lateral view. Valva in lateral view long and relatively slender, with one or more teeth on ventral margin and with apex pointed and sharply curved downward. Valva entirely with- out the large subapical fleshy lobe found in Ceramidiodes and Antichloris and lacking the pulvinus found in Ceramidiodes on base of inner face. Female genitalia (Figure 84) with seventh ster- num forming a large bilobed anterior genital plate and with a large triangular lobe on each side slightly posterior to this plate. The cupules found posterior to these triangular lobes in Antichloris and the deep pockets found at the base of the heart- shaped anterior genital plate in Ceramidiodes are absent in Ceramidia. Ductus bursae with dorsal surface divided into three schlerotized elements: the posterior element tapering and extending anteriorly almost to the central element and pos- teriorly forming the two parts of the wing-shaped posterior genital plate; the middle element long and forked on its posterior margin and the ante- rior element somewhat crescent shaped and lying at the opening of the bursa copulatrix. MISIDENTIFICATION.?Butler (1876:412-413) de- scribed as new the genus Passineura with Pampa fusiformis Walker as its type-species. Moschler (1878:640) shows that Butler's species was not P. fusiformis Walker but a misidentification of that name, and Moschler identifies Butler's species as his (Moschler's) new species, Antichloris phe- monoides. Kirby (1892,158), ignoring Moschler's statement about this misidentification, uses the generic name Passineura for the species P. fusi- formis (Walker) and P. phemonoides (Moschler). Hampson (1898:397) and Zerny (1912:114) agree with Moschler that Butler misidentified Pampa fusiformis Walker but list Passineura Butler as a synonym of Ceramidia Butler. Article 70 of the International Code of Zoo- logical Nomenclature (2nd edition, 1964) on the "Identification of the type-species" [of a genus] states that: "It is to be assumed that an author correctly identifies the nominal species that he . . . designates as the type-species of a new or of an established genus." In paragraph (a), article 70, zoologists are asked to refer such cases as the above to the International Commission of Zoological Nomenclature so that it can use its plenary powers, if necessary, to settle the issue. Since the question here is of small importance for the moment, being whether Passineura Butler is a synonym of Cera- midia Butler or of Hyaleucera Butler (1875) (where Pampa fusiformis Walker now resides), I see no need to appeal to the International Com- mission of Zoological Nomenclature at the present time, and I treat Passineura as a synonym of Hyaleucera. The last-named genus has as its type- species Hyaleucera erythrotelus (Walker) (= Glau- copis erythrotelus Walker, 1854:147). As long as H. fusiformis (Walker) is considered to be con- generic with H. erythrotelus then Passineura is best treated as a synonym of Hyaleucera. If a future reviser decides that these two species are not con- generic then an appeal to the International Com- mission of Zoological Nomenclature would be both desirable and necessary to allow for the availability of the name Passineura. ETYMOLOGY.?The name Ceramidia is a femi- nine noun derived from the Greek classical word keramidis (genitive of keramis, a roof-tile, potter's earth, or clay) and from the feminine (diminu- tive ?) ending ia.

[New synonymy.] Ceramidia fumipennis is easily distinguished from C. phemonoides in the male sex in having the pale gray to white area on the costal area of the upper surface of the hindwing never extending below the lower margin of the cell and the outer angle of this wing (Figure 1). On the undersur- face of the forewing the pale gray area is smaller NUMBER 198 than in C. phemonoides, not extending nearly to vein Cu2, nor extending as far outward toward the outer margin. In C. phemonoides the outer surface of the hind tibia is fuscous; in C. jumipen- nis the hind tibia is entirely white. MALE (Figures 1-4).?Head with occipital area metallic blue-green, frons with two large white spots, palpi white except for fuscous at the tip, neck with red scales behind eyes. Thorax fuscous and metallic bronze or blue-green, patagia and base of tegulae metallic blue-green. A small red area be- hind each eye. Forelegs with white on coxae and femora, midlegs and hind legs with white on coxae, femora, tibiae, and tarsi. Each tympanic hood large, bloated, and fuscous and bronze green in color except for white on lower margin near opening. Abdomen above fuscous and bronze or blue-green, ventral surface fuscous and bronze or metallic blue- green with two large white bands below the spirac- ular line extending nearly to the terminalia. Wings above fuscous. Forewing with a small metallic blue-green or bronze spot on base oppo- site base of tegula. Hind wing above with pale gray to white of costal area extending through the cell and not covering the outer angle. Fore- wing below with a narrow streak of white in middle of costal margin and with an area of pale gray on its base below the cell, extending outward toward outer margin for more than two-thirds of the wing. Hind wing below variable, from nearly entirely fuscous with a small streak of white running from the base through middle of wing to nearly all white or yellowish white except for outer margin and base of costal margin. Length of forewing, 15-17 mm (average 16 mm). Male genitalia as illustrated by Figure 75 (drawn from preparation of holotype of C. catalenca Butler, a junior synonym of C. jumipennis (Walker)), with valva rather long and slender and having a greatly prolonged, sharply pointed, and downwardly bent apex; with ventral margin having a single large centrally placed, downwardly directed tooth and lacking a similar tooth from costa, thus easily distinguished from C. phemonoides. FEMALE.?Unknown. TYPE-DATA.?Described from a single male speci- men, the holotype (Figures 1, 2) from "Ega, on the Amazon" = Teffe, Amazonas, Brazil, col- lected by H. W. Bates and in the collection of the British Museum (Natural History). SYNONYMICAL NOTE:.?Ceramidia cataleuca But- ler, 1872: Type-locality, "E. Peru (Degand)." Described from a single male specimen, the holo- type (Figures 3, 4) is in the collection of the British Museum (Natural History). A comparison of the genitalia of this holotype with the holotype of C. jumipennis shows them to be nearly identical, thus placing C. cataleuca as a junior synonym of the former. This species was thought to be distinct by its describer because of the large amount of pale yellowish white on the underside of the hind wing. The holotype of C. jumipennis (Figure 2) shows only a little of this white on costa and in the cell, while the holotype of C. cataleuca (Figure 4) shows a great amount of this white. This character is very variable in this species. ETYMOLOGY.?The name fumipennis is an adjec- tive in the nominative singular with a feminine ending and agreeing in gender with the generic name. It has the following gender endings: is, masculine; is, feminine; e, neuter. The name is derived from the Latin words fumidus (smoky) and penna (wing) and the Latin suffix is (having). DISTRIBUTION.?This species occurs from Manaus, Brazil, on the Amazon River southwest into the low tropical areas of Bolivia and west and north of Manaus into the tropical areas of Peru, Ecuador, and Colombia. MATERIAL STUDIED.?Sixty-one males were studied from the following localities: BRAZIL: Allianca, below Santo Antonio, Rio Madeira (November, December); Fonte Boa, Amazonas (October); Humayta, Rio Madeira; Igarape Preto, upper Amazons (August, September); Manaus; Manicore, Rio Madeira; Rio Tapajos, Amazonas; Rio Ucay- ala, Amazonas; San Juan, Solimoens; Sao Paulo de Olivenca (June, July, November, December), Teffe, Amazonas (June, September, October, No- vember); Tonantins, upper Amazons (July).

Passineura fusiformis ?Sutler, 1876:412, 413 [not Walker; a misidentincation]. In the male sex C. phemonoides differs from C. fumipennis in having the pale gray to white area on the costal area of the upper surface of the hind wing extending to well below the cell and to well below the outer angle of this wing (Figure 5). On the undersurface of the forewing the pale gray area is larger than in C. fumipennis, extending nearly to vein Cu2 and extending farther outward toward the outer margin. In C. fumipennis the hind tibia is entirely white; in C. phemonoides the outer surface of the hind tibia is fuscous. MALE (Figures 5, 6).?Head and thorax similar to C. fumipennis except the metallic color is usu- ally bronze green. Legs with white on coxae and femora of all three pairs, tibiae and tarsi of all legs mainly dark brown and metallic blue-green or bronze green. Tympanic hood of thorax and abdo- men as in C. fumipennis with large white bands below the spiracular line as in that species. Wings above fuscous. Forewing with a small metallic bronze green or blue-green spot on base opposite base of tegula. Hind wing above with pale gray and white of costal area extending to well below the cell and completely covering the outer angle and outer margin down to vein Cu^ Fore- wing below as in C. fumipennis with a narrow streak of white in middle of costal margin and with an area of pale gray on its base below the cell, extending outward toward outer margin slightly farther than in C. fumipennis. Hind wing below with a white band extending from the base of wing outward through the cell and with costal area above this distinctly blue or green. Length of forewing, 15-17 mm (average 16 mm), exactly the size and variation of C. fumipennis. Male genitalia as illustrated by Figure 76 (drawn from preparation of lectotype), with valva rather long and slender and having a short, sharply pointed, and downwardly bent apex; with ventral margin having several large downwardly directed teeth and in having a single similar tooth project- ing downward from costa, thus differing from C. fumipennis in all of these characters. FEMALE (Figures 23, 24).?Head and thorax similar to the male with the amount of white greatly reduced, especially on the legs, which are fuscous except for a few white scales on coxa of foreleg and femora of hind leg. Thorax with tympanic hood as in the male. Abdomen very similar to the male except white bands are even larger. Wings above and below fuscous except for a small, short streak of white on base of forewing underneath and for a narrow stripe of white in lower one-half of cell on hind wing. Forewing be- low lacking the pale gray area found on its base below the cell in the male sex. Hind wing above without the large pale gray area found in upper one-half of wing in the male sex, sometimes area above cell a lighter fuscous color. Length of forewing, 16 and 18 mm (only two known examples). Female genitalia as illustrated by Figure 84 (drawn from preparation number 6567) and as described above in the generic description. Since the female of the only other species in Ceramidia (C. fumipennis) is unknown to me, I cannot offer specific characters for the present species. TYPE-DATA.?Described from two syntypes from Surinam (sex not stated in the original descrip- tion). This locality is not specifically mentioned in the original description (Moschler, 1876:639-640), but we know from the title of the author's paper that he was specifically treating the fauna of Surinam. One of the two syntypes was loaned to me for study and I designate it the lectotype (Figures 5, 6); it is a male and a designating lecto- type label has been placed on the pin of this specimen. MISIDENTIFICATION.?As mentioned under this heading in the discussion of the genus Ceramidia, Butler, the author of this genus, designated as type of his new genus Passineura the species Pampa fusifortnis Walker. Moschler (1878:640) correctly points out that this is a misidentification and that the species Butler actually had is the species he NUMBER 198 11 (Moschler) describes as Antichloris phemonoides = Cermidia phemonoides. ETYMOLOGY.?The name phemonoides is an ad- jective in the nominative singular with a feminine ending and agreeing in gender with the generic name. It is derived from the Greek, word Phemonon (the daughter of Apollo) and the Greek suffix oides (a likeness of form). It has the same ending in all three genders. DISTRIBUTION.?This species is found from French Guiana west through Surinam, Guyana, and Trin- idad into central Venezuela. Two specimens la- beled "Brazil" (if correctly labeled) place this species also in that country, considerably east, how- ever, of the known distribution of C. fumipennis. MATERIAL STUDIED.?Forty-four males and two females were studied from the following localities: FRENCH GUIANA: Cayenne; St. Jean, Maroni (July, August). SURINAM: Aroewawa Creek, Maroewijne Valley (February). GUYANA: Ida Sabina, Rio Berbrice (March, April). TRINIDAD.

Ceramidiodes Hampson, 1914:255, fig. 36?Draudt, 19l7a:2O7; 1917b:207. Type-species: Ceramidia mathani Rothschild, a junior synonym of Ceramidiodes obscums (But- ler), new combination. Type by original designa- tion and by reason of being the sole included species. Ceramidiodes contains the single species C. obscurus (Butler) and differs from both Anti- chloris and Ceramidia in habitus and by characters in the male and female genitalia. In Ceramidiodes (Figures 8, 26) almost all the sterna of the abdo- men are white; the male genitalia has each valva slender, without teeth on the ventral margin, and has a long narrow pulvinus on inner face of its base; the female genitalia has a heart-shaped an- terior genital plate with deep pockets opposite the base of this plate. Male genitalia (Figure 77) with uncus com- pletely divided, forming two long, entirely separate arms, each spatulate at tip. Behind each uncal arm is a shorter pseuduncus, lobelike and arising from tegumen. Saccus in ventral view somewhat broader than long, not suddenly narrowed as it is in Ceramidia and only slightly projected posteriorly. Center of posterior margin of saccus straight to slightly concave. Aedeagus short and evenly and strongly bent downward near middle. Valva long and slender in lateral view, without teeth on ven- tral margin but with a single short, rounded lobe from just before its middle. Apical one-half or more of valve slender, long, and inwardly curved, with a short fleshy and hairy lobe on outer face just before apex. Valva with a long narrow pul- vinus, projecting inwardly from inner face at base. Female genitalia (Figure 85) with a large, bulg- ing heart-shaped anterior genital plate, with deep pockets on each side at its origin, and with a small triangular lobe on each side along posterior margin of seventh sternum. The cupules or lateroventral depressions found above these lobes in Antichloris are absent in Ceramidiodes, their probable holding or grasping action being taken over by the pockets described above. The posterior genital plate found in related genera is absent and the ductus bursae is large and weakly sclerotized. ETYMOLOGY.?The name Ceramidiodes is a mas- culine noun derived from the genus name Ceramidia and the Greek adjectival suffix odes (like). This ending is specifically assigned the masculine gender as one of the examples given under Article 30 (a) ii of the International Code of Zoological Nomen- clature (1961 and 1964).

Ceramidia phemonoides and Ceramidia fumipennis, the species it most closely resembles in habitus, are easily distinguished from it by having the ventral surface of the abdomen divided through the middle by a median band of fuscous. MALE (Figures 7, 8).?Head with occipital area dark fuscous with a metallic blue-green sheen, frons nearly entirely white. Palpi dark fuscous with white on outer surface of basal segment, neck with an eversible shallow pocket covered with red scales opposite each eye. Thorax foscous with tegula lightly scaled with metallic blue-green on base and patagia heavily scaled with this color. Legs fuscous except for the white coxae of all three pairs of legs. Each tympanic hood large and entirely fus- cous in color. Abdomen above fuscous with bronze green sheen and with ventral surface white from the base through most of seventh segment. Wings above fuscous. Forewing with bronze green along base of costa and along each side of base of anal vein. Hind wing above with silvery white of coastal area extensive, extending from costal margin clear through the cell and to the outer margin except for a small amount of fuscous on outer margin opposite end of cell. Forewing below fuscous in color with a narrow streak of androconial scales through the middle one-third of costal margin and with pale gray or white on base covering one-half or more of wing and with a bronze green sheen on subapical part of wing. Hind wing below fuscous with metallic bronze green sheen on base, sometimes with a large white area below cell and between there and hind margin of wing. Length of forewing, 16.5-17 mm (average 16.90 mm). Male genitalia as illustrated by Figure 77 (drawn from preparation of the lectotype of C. mathani, a junior synonym of C. obscurus and since this is the sole included species in Cerarnidiodes, the characters are as described above in the generic description.

Forewing below almost entirely bronze green with a large submarginal brownish area and lacking the white androconial scales found along the middle of the costal margin in the male. Hind wing below fuscous with an overall bronze green sheen. Length of forewing 17 mm. Female genitalia as illustrated by Figure 85 (drawn from preparation of holotype of C. obs- curus) with characters as given in the generic de- scription and key. TYPE-DATA.?Described from a single specimen, the holotype (Figures 25, 26). The sex of this speci- men was not indicated in the original description but upon examination was shown to be a female. Described from "Forest near Sobral, Rio Purus . . . (J. W. H. Trail)" [Brazil]. Holotype in the collection of the British Museum (Natural History). SNYONYMICAL NOTES.?Ceramidia mathani Roths- child, 1912: Type-locality, "Teffe, Amazons . . . (M. de Mathan)." Described from two male syn- types, to one of which an appropriate lectotype label has been pinned. This specimen also bears the holograph label "Ceramidia mathani Type Rothsch." and is the specimen here illustrated as the male of C. obscurus (Figures 7, 8). The great similarity in habitus of the abdomen of the male lectotype of C. mathani to the abdomen of the female holotype of C. obscurus is the reason the former is treated here as a junior synonym of the latter. ETYMOLOGY.?The name obscurus (dark and ob- scure) is a Latin adjective in the nominative singular, agreeing in gender with the generic name. It has the following gender endings: us, masculine; a, feminine; um, neuter. DISTRIBUTION.?This species is known only from several widely separated localities in Brazil. MATERIAL STUDIED.?Five male and one female specimens are the only specimens I have had for study. They are from Manicore, Rio Madeira; St. Catherine; Sao Paulo; Teffe.

In Antichloris only the basal sterna of the abdominal segments are entirely white (Figures 8, 10, 12), with at least large white spots in the middle of these sterna (Figures 28, 30, 32, 34) (the Caca species group), or this area is fuscous and there are several pairs of white spots on the basal seg- ments near the spiracular lines (the Eriphia species group). Male genitalia (Figures 78-82, 92-102) with uncus completely divided, forming two long en- tirely separate arms, each spatulate at tip. Behind each uncal arm is a shorter pseuduncus arising from tegumen. Saccus in ventral view about as broad as long, not projected as far posteriorly as in Ceramidia, and with posterior margin nearly straight, sometimes slightly concave and sometimes slightly convex. Aedeagus short and evenly and strongly bent near middle with a long, single dorsal needle-like projection from posterior end. Valva not at all slender, broad through basal one-half or more, and base with a rounded outer margin (Caca group) or with this margin produced form- ing a broad lower posterior angle (Eriphia group). Valva with a long apical finger-like projection greatly curved downward or inward and with a long fleshy and hairy lobe on outer face just before apex. Valva lacking the pulvinus found in Ceramidiodes. Female genitalia (Figures 86, 87, 89, 104, 105) with anterior genital plate formed into a broad, bulging lipped lobe, with a large triangular lobe on each side along posterior margin of seventh sternum and with a shallow cupule or lateroventral depression just dorsal of each of these lobes. Pos- terior genital plate absent. Ductus bursae near ostium bursae forming two subtriangular plates, one dorsal and the other ventral. Ductus bursae either not sclerotized at all (except as described above), sometimes weakly sclerotized, and some- times with a large sclerotized element along its dorsal surface for its entire length. SYNONYMICAL NOTES.?Illipula Walker was erected for Sesia melanochloros Sepp, the sole in- cluded species. Sesia melanochloros is a synonym of Antichloris eriphia (Fabricius) and Illipula is therefore a junior synonym of the older name Antichloris, as was pointed out by Hampson (1898: 399). The name Copaena Herrich-Schaffer first ap- peared in 1855 with the sole included species Copaena scapularis Herrich-Schaffer, which is therefore the type of the genus. Copaena scapularis is a junior synonym of Antichloris eriphia and thus Copaena is a junior synonym of Antichloris. Eriphia Herrich-Schaffer, with its type-species Antichloris eriphia (Hubner), designated by Hampson (1898:399), is also a junior synonym of Antichloris. In addition it is preoccupied by the name Eriphia Latreille (1817) in the Crustacea. ETYMOLOGY.?The name Antichloris is a femi- nine noun derived from the Greek classical prefix anti (against or opposed to) and from the Greek personal female name Chloris (especially the god- dess of flowers). Except for the treatment of the Caca species group (below), the generic description given 14 SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY above, and the list of 15 species herein transferred from the genus Ceramidia to the Eriphia species group, it is beyond the scope of the present paper to further treat the latter group. The Caca Species Croup This group contains the two species Antichloris viridis Druce and Antichloris caca Hiibner. In habitus they are distinguished easily from the species of the Eriphia species group in having the sterna of the basal three abdominal segments (1+2, 3, 4) entirely white or with large white spots in the middle of these sterna. They are further distinguished from that group by characters in the valvae of the male genitalia as given in the key and as pointed out above in the generic description.

Antichloris viridis is distinguishable from A. caca in the male sex by having the lower half of each tympanic hood white and in having a small white spot on base of each tegula. In A. caca the tympanic hoods and tegulae are entirely fuscous. In the female of A. viridis the ventral surface of the segment in front of the ostium varies from fuscous to blue-black, dark metallic blue, or metal- lic green to bronze green. A few specimens have this segment tan except for a darker central area. In the single female specimen of A. caca available to me for study, this entire segment ventrally is light tan in color. MALE (Figures 9-16).?Head with occipital area dark fuscous, sometimes metallic blue or green, frons similar, and often but not always with a large central white spot. Palpi dark fuscous, neck with an eversible but shallow pocket, covered with red scales opposite each eye. Thorax with tegulae and patagia fuscous and metallic bronze, green, or blue and each tegula with a small white spot on base. Legs entirely fuscous and blue or green except for coxae of forelegs, which are white. Each tympanic hood large and fuscous in color except for lower half, which is white. Abdomen above fuscous with dark blue, bronze, or blue-green sheen. Ventral surface of abdomen similar except for a large white band extending through segments 1+2, 3, 4, this white covering entire ventral surface of these seg- ments except on segment 4, where it is often rounded or tapered caudally. Wings above fuscous, often entirely so, but also often with forewings covered from base to middle or beyond with a sheen of metallic blue, green, or bronze green. Hind wing above with about three- fourths length of wing on costal area and to middle of cell pale silvery gray and with a very faint streak of white along vein defining bottom of cell. Forewing below fuscous with a narrow streak of white androconial scales through middle one-third NUMBER 198 15 of costal margin, with pale gray on its base cover- ing basal one-half or more, and with a metallic blue or green sheen immediately above this gray area. Hind wing below fuscous with metallic blue or green sheen on base. Length of forewing, 14-19 mm (average 16.55 mm). Male genitalia as illustrated by Figures 78 (drawn from preparation of holotype of the junior synonym C. cyanopasta), 79 (drawn from prepara- tion of holotype of the junior synonym C. musicola), and 80 (drawn from preparation of holotype of A. viridis), with valve having a large, downwardly bent costal arm and with a weakly sclerotized lobe from near middle of the dorsal surface of this arm; with a broad and caudally directed sacculus ending in a dorsally directed ob- tuse projection. FEMALE (Figures 27-32).?Head and thorax sim- ilar to the male except that the white color is absent from the occipital area of the head and from the tegula and reduced or absent on the coxae of forelegs. This white is also greatly reduced on the ventral surface of the basal abdominal segments. The ventral surface of the segment in front of the ostium varies from fuscous to blue black, dark metallic blue, or metallic green or bronze green. In a few specimens this segment is dark tan and darker in the central area. Wings above similar to the male, with light color on costal area of hind wing more reduced in size and darker. Forewing below without the white androconial scales found along the middle of the costal margin in the male and with base of this wing much darker than in that sex. Length of forewing, 14.50-20 mm (average 18.53 mm). Female genitalia as illustrated by Figure 86 (drawn from holotype of the junior synonym C. underwoodi) not distinctly different from A. caca.

SYNONYMICAL NOTES.?Ceramidia musicola Cock- erell, 1910: Type-locality, "Among bananas at Boulder, Colorado, doubtless imported from Cen- tral America." Described from a single male speci- men, the holotype (Figures 13, 14), in the collection of the National Museum of Natural History. This specimen bears the red type label "Type No. 33493." The genitalia of this holotype (Figure 79) shows it to be a junior synonym of A. viridis. Ceramidia cyanopasta Dognin, 1911: Type- locality, "Merida, Venezuela." Described from sev- eral pairs, now in the collection of the National Museum of Natural History. One of these speci- mens is labeled "Type $ " and another is labeled "Type $."

U.S. GOVERNMENT PRINTING OFFICE l?7! -546-3?s / l8 Publication in Smithsonian Contributions to Zoology Manuscripts for serial publications are accepted by the Smithsonian Institution Press, sub- ject to substantive review, only through departments of the various Smithsonian museums. Non- Smithsonian authors should address inquiries to the appropriate department. If submission is invited, the following format requirements of the Press will govern the preparation of copy. Copy must be typewritten, double-spaced, on one side of standard white bond paper, with IVJ" top and left margins, submitted in ribbon copy with a carbon or duplicate, and accompa- nied by the original artwork. Duplicate copies of all material, including illustrations, should be retained by the author. There may be several paragraphs to a page, but each page should begin with a new paragraph. Number consecutively all pages, including title page, abstract, text, litera- ture cited, legends, and tables. The minimum length is 30 pages, including typescript and illus- trations. The title should be complete and clear for easy indexing by abstracting services. Taxonomic titles will carry a final line indicating the higher categories to which the taxon is referable: "(Hymenoptera: Sphecidae)." Include an abstract as an introductory part of the text. Identify the author on the first page of text with an unnumbered footnote that includes his professional mailing address. A table of contents is optional. An index, if required, may be supplied by the author when he returns page proof. Two headings are used: (1) text heads (boldface in print) for major sections and chap- ters and (2) paragraph sideheads (caps and small caps in print) for subdivisions. Further headings may be worked out with the editor. In taxonomic keys, number only the first item of each couplet; if there is only one couplet, omit the number. For easy reference, number also the taxa and their corresponding headings throughout the text; do not incorporate page references in the key. In synonymy, use the short form (taxon, author, date:page) with a full reference at the end of the paper under "Literature Cited." Begin each taxon at the left margin with subse- quent lines indented about three spaces. Within an entry, use a period-dash (.?) to separate each reference. Enclose with square brackets any annotation in, or at the end of, the entry. For references within the text, use the author-date system: "(Jones, 1910)" and "Jones (1910)." If the reference is expanded, abbreviate the data: "Jones (1910:122, pi. 20: fig. 1)." Simple tabulations in the text (e.g., columns of data) may carry headings or not, but they should not contain rules. Formal tables must be submitted as pages separate from the text, and each table, no matter how large, should be pasted up as a single sheet of copy. Use the metric system instead of, or in addition to, the English system. Illustrations (line drawings, maps, photographs, shaded drawings) can be intermixed throughout the printed text. They will be termed Figures and should be numbered consecu- tively; however, if a group of figures is treated as a single figure, the components should be indicated by lowercase italic letters on the illustration, in the legend, and in text references: "Figure 9b." If illustrations (usually tone photographs) are printed separately from the text as full pages on a different stock of paper, they will be termed Plates, and individual components should be lettered (Plate 9b) but may be numbered (Plate 9: figure 2) . Never combine the numbering system of text illustrations with that of plate illustrations. Submit all legends on pages separate from the text and not attached to the artwork. An instruction booklet for the preparation of illustrations is available from the Press on request. In the bibliography (usually called "Literature Cited"), spell out book, journal, and article titles, using initial caps with all words except minor terms such as "and, of, the." For capitalization of titles in foreign languages, follow the national practice of each language. Underscore (for italics) book and journal titles. Use the colon-parentheses system for volume, number, and page citations: "10(2) :5-9." Spell out such words as "figures," "plates," "pages." For free copies of his own paper, a Smithsonian author should indicate his requirements on "Form 36" (submitted to the Press with the manuscript). A non-Smithsonian author will receive 50 free copies; order forms for quantities above this amount with instructions for pay- ment will be supplied when page proof is forwarded. i
