BEES IN THE COLLECTION OF THE UNITED STATESNATIONAL MUSEUM.?3.1
By T. D. A. COCKERELL.0/ the University of Colorado, Boulder.
Having spent some weeks in Washington, arranging the exoticbees in the National Museum, I found it necessary to set aside a largenumber of undetermined species for farther study. The neotropicalfauna especially is represented by large collections which prove tocontain many new and little-known species. The museum at the timeof my visit contained about 460 determined species from south ofthe Mexican boundary (including the West Indies), but when theundetermined material has all been classified the number will prob-ably be not less than 700. Various parts of the Old World are alsorepresented by collections which add considerably to our knowledgeof distribution and include forms new to science.The present j)art includes the neotropical social bees of the genusMeUpo7ia. These insects, as also the species of the allied genusTrigona^ present a great number of races or very closely alliedspecies, as do the ants. The group of Melipona fasclata, for example,with its local forms in Brazil, British Guiana, Trinidad, Panama,Costa Rica, etc., recalls the condition found among the ants of sucha genus as Caniponotus. The several forms are also related to oneanother in much the same degree as the "representative species" inthe islands of an archipelago, as the birds of the Galapagos Islandsor the Lesser Antilles. The natural inference is that this productionof numerous closely allied forms is not due primarily to anythingpeculiar about the variability of social bees or ants, but comes aboutas a by-product of isolation. It appears probable that thb matingsexes of these insects almost always come from the same nest, so thatthe several colonies give rise to others through a process of inbreed-ing. The tendency under these circumstances is toward a homo-

It must be stated, however, that one form ofdichroism appears to prevail within the limits of the colonies. Theblack and red variegation of the legs, which gave rise in one speciesto the name M. variegatipes, seems always to vary to a condition(probably recessive) in which the black pattern is absent. Owingto the existence of so many closely allied forms, the interpretationof many of the published descriptions, often without the citation ofany exact locality, becomes very difficult. The United States Na-tional Museum possesses a large collection of these bees received fromDr. H. Friese, and I have followed his determinations whenever therewas no reason to the contrary. In a few cases I have been obligedto dissent, and have given my reasons for so doing.XYLOCOPA FORMOSA Smith.A. female about 22 mm. long, from Mexico, D. F. (J. R. Inda, No.52), appears to be large for this species, but it otherwise agrees,especially in the striking characters of the head described by Maidl.Is it possible that X. loripes Smith is the male of this species ?XYLOCOPA VIRESCENS Lepeletier.Alhajuelo, Canal Zone, May 29, 1912 (Busck). This is a speciesof the X. hrasilianormin group, remarkable for its large size andgreen wings. It agrees exactly with Lepeletier's measurement, andalthough cited by Maidl as a synonj^m of l?rasiUano?'U77i, I believe itis a perfectly valid species. There are three large black species withsimilar green wings, separable thus

A male, differingfrom the female only in the usual sexual marks, and the abdomenhaving very distinct but narrow marginal white hair-bands at sidesof segments 2 to 5. The cheeks have erect white hair, mixed withblack above. Face narrow, orbits distinctly converging above;cl3^peus, supraclj^peal mark, lateral face-marks, labrum, broad stripeon mandibles, front of scape, and narrow stripe on basal part offlagellum, all very pale yellowish ; clypeus with scattered black hairs.The tegulae are dark, with a red spot in front and the outer marginred; in typical varians they are wholly red.XYLOCOPA TABANIFORRnS Smith.A male, Mexico (C. F. Baker collection, 2499). This has blacktegulae ; Smith, describing a female, says they are ferruginous. Theface-marks agree with those of var. clmiquiensis Perez, except thatthey are sulphur yellow.XYLOCOPA RUFINA (Maidl).Both sexes from Mexico (C. F. Baker collection, 2321). Maidldescribed this as a variety of X. tahaniformis, but I believe it to bedistinct, since the abdomen of the male is broad like that of thefemale, and the orange-ferruginous hair on the abdomen is very dis-tinctive. The male also has larger eyes than tabaniformis, and thehair on the cheeks is black. There are no lateral face-marks. Bakerhad labeled this " tahaniforrnis?''''XYLOCOPA RUFINA ILLOTA, new subspecies.Female.?Length, 18 mm. Similar to X. ruflna, with interruptedorange-fulvous bands on abdomen, but hair of head and thorax darkmouse-gray (that of cheeks gray, not black) ; process of labrum moreslender; surface of clypeus perfectly dull (moderately shining inruflna) ; tegulae black.Mexico (Baker collection, 2154).Type.?C2it.

A male, verylike M. anicula (Vachal), but distinguished by the structure of thehind legs. MESOTRICHIA STUHLMANNI ALTICOLA, new subspecies.Female.?Length about 16 mm.; anterior wing 13.5 mm. Wingsvery dark, not noticeably pale at base; face covered with silvery-white hair, which extends far up on sides of front ; dorsum of thoraxposterior to level of wings, and whole of dorsal surface of first ab-dominal segment, covered with bright yellow hair; mesopleura withblack hair; tegulae with a large ferruginous spot on outer side.Male with flagellum red beneath ; thorax above covered with yellowhair; yellow hair of abdomen beyond first segment sparse; wingspaler than in female.Mount Kilimanjaro, 2 females, 3 males (W. L, Abbott).The specimens have been in alcohol, and can not be very satisfactor-ily described, but the yellow on the first abdominal segment will dis-tinguish the insect from true M. stuhlmanni (Kohl). The female issmaller than M. divisa (Klug) , and differs not only in the pubescence,but also in the more delicate punctures of the abdomen.Type.?C^ii. No. 20700, U.S.N.M.This is very possibly a distinct species ; it is probably the same in-sect which Sjostedt collected on Kilimanjaro, which Friese recordedas Xylocopa caffrariae^ var capensis Enderlein. The name capensisis preoccupied in Xylocopa, and I am confident that our insect is notthe same as Enderlein's which came from " Capland " and Port Natal.M. stuhlmanni is also recorded from Kilimanjaro.XYLOCOPA BAROMBIANA (Strand).Mount Kenia to Fort Hall, British E. Africa, altitude 8,500 feet(E. A. Mearns). Both sexes. Described by Strand as a variety ofX. carinata Smith, from which it differs in the male by having thethorax light-haired only anteriorly above, and on anterior part ofmesopleura (in the manner of the form producta Smith), and thewings dark as in the female, not light at base. The hind femora andtrochanters are both dentate. Strand's type came from BarombiStation in the Cameroons, but it appears to be entirely the same insect,except that ours have an imperfect narrow smooth line on the clypeus,which was absent from Strand's example. The female is almostexactly like X. carinata., but the region just above the top of theeyes is less densely punctured, showing the shining surface, andthe smooth band on each side of the clypeus is much narrower andJess developed. X. carinata is represented by a series of forms in

MESOTRICHIA TENUISCAPA (Westwood).Buitenzorg, Java, March, 1909 (Bryant and Palmer). Describedby Westwood under the subgenus Platynopoda of Xylocopa, but re-ferable to Mesotrichia in the broad sense.XYLOCOPA FENESTRATA (Fabricius).Chikar Kot, North West Provinces, India, April 1, 1906 (FrankBenton); Wazerabad, Punjab, April, 1906 (F. Benton).XYLOCOPA COLLARIS, variety BRYANTI, new variety.Male.?Length 19 mm. Agreeing with X. coUaris Lepeletier instructure and appearance, but wings darker; a good deal of blackhair on front; middle tibiae with black hair posteriorly, and theirtarsi with long black hair externally and behind, except on the lastthree joints; hind tibiae with the hair on inner and posterior sur-faces all black, and their tarsi with black hair, except a very littlepale at base in front. The wings have a beautiful violet tint.Buitenzorg, Java, April, 1909 (Bryant and Pahner).Type.?C^t. No. 20701, U.S.N.M.Lepeletier described X. dejeanii, now referred by authors to coUa-7'is. from a male in the Dejean collection said to come from Java.It agrees with the present insect in having the hair of the thoraxpale (though in hryanti there is a band of black hair along extremebase of scutellum), and the pale hair of abdomen above confined tothe first two segments (though in hryanti it fails to reach the apicalmargin of second segment in the middle third). On the other hand,the base of mandible has only a yellow spot, as in other collaris forms(Lepeletier may be misleading where he seems to infer more), thetegument of the thorax is distinctly greenish (Lepeletier says black,as in the Indian form hinghami Cockerell), the long hair fringingapical part of abdomen is all black (Lepeletier says red and blackmixed), and the hair on four posterior legs is as described above,the black fringe abruptly separated from the white on middle tarsi(Lepeletier says white, mixed with black hairs). It is thus evidentthat our insect is not the true dejeanii., but whether it is a distinctsubspecies (as seems probable) can not now be decided.XYLOCOPA PICTIFRONS Smith.Male.?Soochow, China (N. Gist Gee, 141). The scape is curvedand entirely black. This is Smith's male pictifrons; Bingham's is,accordina; to Maidl. X. attenuata Perez.

Black, the abdomen with a very ob-scure bluish tint; clypeus, supraclypeal mark, broad lateral marksreaching to level of lateral ocelli (at upper end a little divergentfrom orbit), transverse mark on labrum, and minute dot on base ofmandibles, all ivory color; antennae black, third joint a little longerthan following three united ; inner orbits parallel, the front as broadas face; head and thorax with very pale ochreous hair, face withscattered brown hairs, middle of front and region of ocelli with muchblack or dark fuscous hair; sides of metathorax with some dark hair;legs with brownish-black and pale hair ; anterior tibiae and tarsifringed with long pale hair behind, but with dark hair in front;middle legs with more black hair, that on tarsi all dark, except somelong glistening light hair on outer side above ; hair of hind legs muchlike that of middle pair, but mainlj^ dark on middle of tibiae pos-teriorly ; hind femora beneath with much branched black hair ; hindfemora broad, angulate beneath basally; hind tibiae with inner faceflat, apex on outer side with a snout-like projection; tegulae black;wings rather dilute brown, with delicate rosy tints in the apical field
;
abdomen with long and loose very pale ochreous hair on first threesegments, on the third mixed with black; the remaining segmentswith very long loose black hair.Abottabad, North West Provinces, India, April, 1906 (Frank Ben-ton). Two males.This insect looks superficially exactly like the common X. collarishinghami Cockerell, and has probably been overlooked on this ac-count. It is very distinct in many important characters ; the parallelorbits, shorter labial palpi, much shorter black scape, smaller ocelli,much greater distance between antennae and middle ocellus, smoothpractically impunctate tegulae, shorter (triangular rather than cunei-form) second submarginal cell, more sparsely punctured abdomenwith long loose hair, and the structure of the hind legs.Type.?Cfit.

Gist Gee, 143).Superficially very like X. sinensis Smith, but structurally very dis-tinct. Smith's original (1852) description of the male leaves onedoubtful, but his later (1871) one is sufficiently convincing, thoughlacking in detail. The above brief account will make recognitioneasier. Perez (1901) gives fuller details and especially describesthe structure of the hind legs.XYLOCOPA SONORINA Smith.Buitenzorg, Java, March, 1909 (Bryant and Palmer). Onefemale of this little-known species.The middle ocellus is situated in a V-shaped basin; the clypeushas broad smooth swollen borders, and near the apical margin apair of opaque black spots emitting hairs; labrum trituberculate

More robust ; sixth segment with a large yellow mark acxiticauda, new species.Less robust; sixth segment entirely black bryanti, new species.These are all quite distinct from the Indian C. hieroglyphicaSmith, which Friese records from Buitenzorg. They are also readilydistinguished from the allied Philippine Islands species. The darkscape is characteristic of the Java forms.CERATINA OBTUSICAUDA, new species.Male.?Length a little over 7 mm. Black, with bright lemon yel-low ornaments, as follows: Clypeus (except margins, the black mar-gin rather broad above, and at sides of upper part), transverse supra-clypeal mark (broadly angulate above), narrow lateral face-marks(becoming linear above, and ending a little above level of antennae),large quadrate spot on labrum, narrow band on cheeks, narrow bandon prothorax above, upper m^argin and broad apical part of tubercles,scutellum, apex of anterior femora (apical half beneath), all thetibiae on outer side, band (inclosing a spot on each side) on first ab-dominal segment, bands on second to fourth segments (on secondvery narrow except at sides, where it is abruptly enlarged andnotched, on third also abruptly enlarged at sides but not notched),sixth segment Avith a large semilunar patch. Middle of clypeus witha distinct keel; antennae dark; mesothorax distinctly and quiteclosely punctured anteriorly, smooth and polished in middle, dulland rough along posterior margin; mesopleura densely punctured,with a shining spot above; tegulae rufous; wings strongly dusky.

There are slight differences in the punctures of head andthorax hard to describe ; thus the mesothorax posteriorly, instead ofhaving an abruptly defined perfectly opaque band, has a broader one,visibly consisting of punctures, which gradually thin out anteriorly.The difference in structure between the two species, as regards theend of the abdomen, is like that between the American C. dvpla andC. 77iexicana, except that acuticauda has not salient lateral angleslike those of mexicana.

From the same placeis a specimen of the similarly colored Augochlora ignita Smith.CERATINA MORRENSIS Strand.Females.?San Bernardino, Paraguay (K. Fiebrig) . One is markedNovember 1, at flowers of Zea mays. The three specimens before mehave the dimensions of Strand's variety cuprifrons; the abdomenvaries from brassy-green to blue-green and almost black. The strongviolet tints, especially about the head, are very beautiful. This isclosely allied to C. cupreiventrls Smith from Ega, which Ducke hasproposed to treat as a synonym of C. maculifrons Smith, but thelatter is constantly much smaller and so far as I know always readilyseparable. CERATINA VIRIDULA Smith.Female.?Paraiso, Canal Zone, Panama, February 8, 1911 (Busck).Smith describes only the male; the female is like a small O. laetaSpinola, but there is a transverse white spot on the black apicalmargin of clypeus. Ducke makes this species a synonym of C. laeta.,but I consider it quite distinct.CERATINA BUSCKI, new species.Male.?Length nearly 4.5 mm.

Thelabrum and clypeus are honey color ; scape honey-color in front ; an-terior legs with long clear red hair ; hair at end of abdomen grayish-black. Cresson described only the female, which I have from Guate-mala. I believe the Panama insect to be its male, although it isevidently not the insect described by Friese as male mexicana. Thematter will have to remain a little uncertain until we have both sexesfrom Panama. PTILOGLOSSA CKAWFORDI, new species.Male.?Length about 19 mm.

Crawford in recognition of his worli onthe bees of Costa Rica, and of the fact that he had separated thespecies as new before I saw it. P. crawfordi is a very distinct andunique species, easily known by its color and the long third antennaljoint. The spurs of the hind legs are quite ordinary, not modifiedas in P. ollantayi Cockerell, P. Tnatutina Schrottky, and P. mexicanaCresson. The insect is not a typical PtilgoloHsa^ but it falls in thatgenus better than elsewhere.

A si)ecimen from Vachal, labeled " Orocisa,sp.", evidently prior to the description of calceata.Genus OEDISCELIS Philippi.Philippi based this genus (186G) on two species, 0. minor Philippiand 0. vermdis Philippi ; the latter i^ herewith designated as thetype. In later years species have been described by Friese, Ducke,Schrottky, and Brethes. Mr. J. C. Crawford has made the surpris-ing discovery that Ashmead's genus IlyJaeosoma (1898) is apparentlyidentical with Oediscelis. Ilylaeosoma was based on H. longicepsAshniead, from St. Vincent, West Indies; and in 1906 a secondspecies, U. asTimeadi Crawford, was described from Costa Rica. Thetype of Oediscelis is, unfortunately, not available, but the UnitedStates National Museum contains specimens of 0. alhida Friese,O. styliventris Friese, and 0. inermis Friese. These species ofOediscelis are very like Prosopis, but more hairy. The cheeks andunder side of abdomen of 0. styliventris have long white hair, butthe species of Hylaeosoma are very little hairy. The species of Oedis-celis and Ilylaeosoma ashmeadi female have white hair on underside of abdomen. The female II. longiceps is broken, so this char-acter can not be made out, but the male lacks the white hair, whereinit does not difl'er m.aterially from male 0. alhida^ etc.Comparing the males of //. longiceps and 0. alhida^ they aresimilar in appearance, with the same long (oval) head and very long(high) middle lobe of clypeus, but longiceps has no light face marks.They agree in the strong median groove of mesothorax, and bothhave a large stignui. The venation presents important differences;O. alhida has the second submarginal cell large and quadrate, withfirst recurrent nervure meeting first transverse cubital; //. longicepshas (he second submargmal cell very small, with first recurrentnervure falling short of it by a distance nearly equal to width ofsecond submarginal cell. In the Ilylaeosoina the basal nervure falls
186 PROCEEDINGS OF THE NATIONAL MUSEUM. tol. 55.fihort of transverse median a distance at least as great as length oftransverse median, but a lesser distance in the OedisceUs. Thefemales of the two species agree in having little hair on hind legs.flylaeosoma ashmeadi female has second submarginal cell large, withfirst recurrent nervure falling only a little short of it, and basalnervure does not fall far short of transverse median.O. styliventris male has long antennae, and first recurrent nervurefalling short of second submarginal cell. O. inermis male has simi-lar characters, but hind femora angled below. The face marks ofmale inermis and styliventris are very different.It thus appears that Oediscelis contains quite diverse elements,and so far as external characters go it is difficult to separate it fromHylaeosoma. It has not been possible to compare the mouth parts orgenitalia. Various generic names have already been proposed (Pseu-discelis for O. rostrata Friese, Protodiscelis for O. -ftebrigi Brethes,Prosopoides for 0. paradoxa Ducke) for species of Oediscalis takenin the broad sense, and if all these bees are regarded as belonging toa single genus it will be hard to exclude Hylaeosoma.Ducke cites Chilicola Spinola (1851) as doubtfully identical withOediscelis. If the two are identical, Chilicola has priority. I havea pair of bees which I received as Chilicola pleheja Spinola, but theydo not agree with Spinola's diagnosis of the genus, and are, in fact,Panurgids, closely allied (at least) to Panurginus herbsti Friese.If Hylasosoma is regarded as a subgenus of Oediscelis it will ap-parently be necessary to restrict it to the West Indian H. longiceps.CENTRIS HAEMORKHOmALIS (Fabricins).St. Andrew, Jamaica, April 1898 (C.

Smith, himself, in de-scribing M. mondury Smith (which Marianno says is a synonym ofrufiventris) , remarks that ruflventris differs by having the innerorbits of eyes pale and the scutellum black.

TRIGONA BIROI Friese.The type of this species must be considered to be one of those col-lected in New Guinea by Biro. Friese records it at the same timefrom the Philippine Islands, where it seems to be common. Speci-mens come from Los Banos (Baker), and others were collected byC. K. Jones in a locality not specified. Three are from flowers ofNiya fruticans, "Lamao, Batan," February 26, 1916 (P. J. Weeter).For the present it is assumed that all these insects are the same, butit may be that the Philippine form is distinct from that of NewGuinea, and possibly there is more than one sort in the Philippines.The specimens are mostly in poor condition, so that it is impossibleto be sure of all their characters. The Philippine T. Mroi has a redscape, and although very close to the Australian T. carbonaria, I amsure it is a distinct species.TETRAPEDIA CALCAP.ATA Cresson.St. Lucrecia, Vera Cruz, Mexico (F.

The disk of mesothorax is shining between thepunctures. MEGACHILE DIMIDIATA Smith.Meade-Waldo ^ states that M. velutina Smith is a synonym of dimi-diata. The species is said to have red antennae and fulvous legs, andMeade-Waldo remarks that " the original descriptions of both spe-cies distinctly state that the legs are fulvous." As a matter of fact,the descriptions do not so state, but imply that they are black, withfulvous hair. M. dimidiata is said to have red antennae. M. ery-thropoda Cameron, from Singapore, is also of this immediate alli-ance; it has red legs and the scape is rufous. A female labeledPunjab and United Provinces, India, VI-X (K. L. Woglum), isevidently the genuine M. velutina, described from " northern India."It has black legs and antennae. The insect from Trong, Lower Siam,collected by Dr. W. L. Abbott in 1899, and identified by me as M.velutina, is smaller (length 16 mm.), with brighter red hair, andouter margin of apical half of mandibles much more convex. Theantennae are black, but the legs obscurely more or less reddish. Thisinsect represents a distinct subspecies, and may be known as Mega-chile velutina ahhottiana.If, as is quite probable, all these insects are to be regarded assubspecies of M. dimidiata, the nomenclature will be
