BEES IN THE COLLECTION OF THE U. S. NATIONALMUSEUM. L By T. D. A. COCKERELL,Of the University of Colorado, Boulder. In all large museums, the entomological collections tend to accumu-late faster than they can be worked up. New species may be col-lected, and remain unstudied for many decades, and perhaps eventu-ally be described from specimens captured many years later. Thus,I have recently had occasion to work up some bees from Mexico inthe Berlin Museum, collected by Ferdinand Deppc as long ago as1829. Several were still new, but others had been published in themeanwhile by Cresson and myself. In the case of the United StatesNational Museum, the collections do not date so far back, but thereis nevertheless a quantity of valuable material among the bees, whichdeserves to be described or reported. It will be the purpose of thisseries of papers to discuss such portions of this material as may besubmitted to the present writer from time to time.In the descriptions of the venation the following abbreviations areused: s. m. = submarginal cell ; r. ti. = recurrent nervure; t. c. = trans-verse-cubital nervure; 6. 7i. = basal nervure; t. m. = transversomedialnervure.CERATINA (CERATINIDIA) HIEROGLYPHICA, var. JAPONICA, new variety.Female.?Prothorax, including tubercles, entirely black. Thespecimen is of the full size of liieroglypliica; the light reversed T on theclypeus has the arms longer than the stem, and the latter is partlydivided into two parts by a median longitudinal black line; the lat-eral face-marks are reduced to a longitudinal mark above and atransverse mark below; the mesothorax has two slender discal lines,and a short mark above each tegula; the scutellar patch is deeplynotched in front; the other markings call for no remark. Scapeentirely black.Habitat.?Japan (Koebele). C.liieroglyphica is quite variable, butthe mainland forms, including the Chinese var. morawitzii Stadel-mann, always have yellow on the prothorax, so far as I know.Tifpe.?Cat. No. 13420, U.S.N.M. Proceedings U. S. National Museum, Vol. 39?No. 1806. 635 636 PROCEEDINGS OF THE NATIONAL MUSEUM. vol.39.A word may be added concerning the Philippine species of Cera-tinidia. As described, they can be separated as follows:Larger, length 9 to 11 mm., clypeus marked with yellow, scape with yellow only inmale (Philippines, see Ashmead) hieroglyphica Smith.Smaller, length 7 mm. or less 1.1. Clypeus, and scape in front yellow; "female" (?male) compacta Smith.Clypeus only marked with yellow 2.2. Scape of female nearly all yellow; lateral face-marks of female not divided into sepa-rate marks (Manila) -philippinensis Ashmead.Scape of female black; lateral face-marks divided tropica Crawford.The exact locality of comjjacta is unknown. I think it probablethat it came from one of the southern islands, as the greater develop-ment of yellow is characteristic of the more southern species of Oera-tinidia. There may perhaps be some doubt about the reputed sexesof the types of comjmda and ijihiliypinensis. Some years ago I hastilyexamined the ty|3e of i)hilii)pinensis and sketched the face-marks,which are essentially as in hieroglyphica. The vertical mark on theclypeus is strongly notched above. The difference in the lateralface-marks of tropica and philippinensis, as given in the table isprobably due to individual variation; at least, hieroglyphica varies inthis manner. It is probable that C. hieroglyphica does not reallyoccur in the Philippines, being represented there by the smaller forms(extremely closely allied to it) called philippinensis and tropica.Since writing the above, I have received from ]\Ir. S. A. Rohwerparticulars concerning C. tropica and philippinensis, each of which isrepresented by both sexes in the National Museum. The two formsare separable as follows: Female.Mesothorax with two pale lines; tibiae yellow, black beneath; abdominal markingsheavy, broader; clypeus with a large light reversed T; lateral face-marks not divided;scape partly light philippinensis Ashmead.Mesothorax unmarked; tibiae nearly entirely black; abdominal markings much nar-rower; clypeus with only a transverse subapical light bar; lateral face marks eachdivided into two spots; scape dark tropica Crawford.Males.Pale spot on scutellum quadrate; tibiae yellow except a black spot beneath; clypeusyellow; lateral face-marks broader; scape partly light philippinensis Ashmead.Pale spot on scutellum triangular; tibiae black except a pale line above; clypeus dark,with a very broad light bar, which has a median lobe or process above; lateral face-marks narrower; scape dark tropica Crawford.APIS INDICA JAPONICA Radoszkowski.

Scutellum dull yellow; second abdominal segment vari-ably fulvous, always so at base. Japan, two examples (Mitsukuri) ; Swatow, China (Koebele).Male.?Abdomen broad and short, black without bands, but withdense pale hair at base. Japan, No. 127.This is a feebly distinguished subspecies, perhaps originally confinedto Japan, but now occurring also in China. It always has thelabrum more or less reddish or yellowish, as usual in the indica group.Ashmead makes A. cerana Fabricius a distinct species, with sinensisSmith and jayonica Radoszkowski as synonyms. The identity ofcerana seems to be doubtful, and sinensis is not the same variety (ina restricted sense) as ja'ponica. Smith records A. nigrocincta Smithalso from Japan. I have a Chinese nigrocincta from Smith's collec-tion, and can not agree with Buttel-Reepen's view that it is identicalwith peroni Latreille. True peroni, as described by Latreille, has thefulvous color confined to the first three abdominal segments, whilenigrocincta has all the segments fulvous, with black borders. APIS INDICA PERONI Latreille. I refer here to a series of specimens from Pekin, China (M. L, Robb)and Foochow, China (J. P. Grant). The amount of fulvous on theabdomen varies, from that required by the original description (firsttwo segments fulvous except broad hind margins, base of third fulvous)to the small amount at base described for the variety picea Buttel-Reepen. These are evidently only individual variations. The scu-tellum is usually dark, but sometimes dull yellow. There is also aworker peroni from Horisha, Formosa (T. Fukai).

The area of themetathorax is dull and without evident sculpture, and the abdomenis rather long. As seen from above the general size and shape recalls0. fulviventris Latreille, but fulviventris has a larger head, a blue-black abdomen, and a brilliantly shining area of metathorax. 0.fulviventris has an orange scopa, and the structure of its clypeus showsa certain approach to the condition in 0. mitsukurii.OSMIA MATSUMURiE, new species.Male.?Length about 8^ mm. ; head and thorax very dark bluish-green; abdomen dark olive green, the apical margins of the segmentsextremely narrowly, hardly noticeably, testaceous; antennae long andslender, black, last joint normal; face with abundant long white hair,as also cheeks below; more or less pale hair on upper part of head, butsides of front, vertex, and upper parts of cheeks with a good deal ofblack hair; head and thorax quite closely punctured, scutellum lessclosely; area of metathorax dull, without evident sculpture, some-what shining in certain lights; hair of thorax long, slightly yellowish,not mixed with black; tegulae piceous, slightly rufous in middle;wings brownish-hyaline; recurrent nervures entering second sub-marginal cell at about the same distance from base and apex, whereasin 0. mitsukurii the first recurrent enters about twice as far from thebase as the second from the apex ; legs black with pale hair ; last twotarsal joints ferruginous; hind basitarsus simple with ferruginous hairon inner side; abdomen with scanty long hair like that of the thorax;sixth segment entire, quite simple, not reflexed; seventh entire,broadly truncate ; ventral segments quite simple ; stipites simple, witha mere obtuse median angulation; notch in sagittal plate a littlelonger than half breadth of plate.Habitat.?Sapporo, Japan (Matsumura).

Matsumura, Sapporo Agricultural Col-lege. This is a Japanese form of terrestris, regarded as a distinctspecies because the European terrestris seems to present no such color-variety. B. terrestris jajjonicus Friese, 1909, has the end of the abdo-men black; it may perhaps be a variation of sajjporoensis, but if so,the name japonicus is not available, having been earlier used byDalla Torre.

Very likeB. lapidarius Linnaeus, but malar space shorter. Perez considersthat it is structurally nearer to B. terrestris. The pubescence ofignitus varies, the black becoming a dark chocolate brown, as is alsoseen in B. hsemorrlioidalis. This brown variation is especially markedin a female labeled "South Cliina." This Chinese ignitus is readilyknown from B. simillimus Smith by the paler wings.Proc.N.M.vol.39?10 43 642 PROCEEDINGS OF THE NATIONAL MUSEUM. vol.39.

It looks much like hraccatus Friese,but differs in the antennae, mandibles, etc. It is very close toB. hortorum, but distinct.The following characters may be noted: Mandibles stronglynotched near inner apical corner; third antennal joint about as longas 4 + 5; third s. m. much longer than in liortorum; apical segmentsof abdomen whitish-red, black abdominal band narrow, thoracic bandmuch narrower than in liortorum.CHELYNIA ELEGANS Cresson.Two from Flagstaff, Arizona, at flowers of Iris, June 11, 1909(F.

HABROPODA PEKINENSIS, new species.Male.?Closely related to //. zonatula Smith; on comparison witha zonatula from Smith's collection (Nicopolis, May, 1836) the follow-ing differences are found: A little less robust; abdomen narrower,less triangular, more as in Antlioyhora; pubescence paler, not so red;flagellum longer and more slender, fourth antennal joint much longer;first r. n. not quite reaching apex of second s. m.; black on clypeusreduced, the middle broadly yellow to top, the large black markingsvariable, but constricted in middle; pygidial plate much broader;anterior femora strongly keeled beneath at base; hind tarsi red.The anterior coxse have the characteristic long backwardly-directedspines, and the hind basitarsi the great flattened lamina.

These females differ from thetype as described by Bingham and Smith by having the metathoraxblack-haired. The hair of the thorax above is not "grey," as Bing-ham states, or " bluish-white, tipped with black," as Smith has it,but is very pale blue mixed with black. This species strongly imitatesMesotridiia ahhotti Cockerell, which lives in the same region.MEGACHILE XYLOCOPOIDES Smith.Five females, Mansfield, Louisiana, at flowers of Helenium tenui-folium, July 4 and August 22 (F.

The allied M. dimidiatavaries in the same manner, according to Bingham. The one fromthe mountain is smaller than the others.HETERANTHIDIUM CHIPPEWAENSE (Graenicher). I am indebted to Doctor Graenicher for a cotype of his Anthidiumchippewaense; it proves to belong to Tleteranthidium.DLANTHIDIUM ILLUSTRE (Cresson).At Flagstaff, Arizona, at flowers of his, June 11, 1909, Mr. F. C.Pratt took a large variety of the female of this species, about 17 mm.long, the width of the abdomen fully 6 mm. The wings are very dark;the first r. n. joins the second s. m. a short distance from base (as in 644 PROCEEDINGS OF THE NATIONAL MUSEUM. vol. 39.A. conspicuum) , and the second goes a like distance beyond apex.There is a small pulvillus, present also in typical illustre. I thinkthere is no doubt that Anthidium illustre must be referred toDiantliidium. The Flagstaff specimen also has these characters:First two abdominal bands notched behind laterally; black on innerside of hind femora not notched; other colors, of head, legs, etc., nor-mal; hair of face, and head and thorax above strongly reddish;yellow occipital band not interrupted. This female takes on some ofthe color characters normal for the male. It is possible that a dis-tinct subspecific form of D. illustre exists in the region about Flag- staff, but more material is needed to decide this.NOMADA BELFRAGEI, var. XANTHOGASTER, new variety. Female.?Agrees with Cresson's description of N. hefragei, exceptas follows: Only a slight blackish suffusion about ocelli; thoracicmarkings clear lemon yellow; abdominal segments 1 to 5 each witha very broad lemon yellow band, but those on first and second nar-rowly interrupted in middle, and that on first including a small redspot on each side posteriorly; venter with yellow spots down themiddle, those on segments 3 and 4 large and conspicuous. As intrue helfragei (concerning which I have notes from Mr. Viereck, basedon Cresson's type), the third antennal joint is conspicuously largerthan the fourth, and the basal nervure meets the transversomedial.The second s. m. is considerably narrowed above, and receives thefirst r. n. a little beyond the middle. The anterior coxal spines arepresent, but very short. From the related N. wheeleri Cockerell thisis easil}^ known by the entirely terra-cotta red mesothorax and meta-thorax. Supei-ficially, it looks exactly like N. lamarensis Cockerell,but is easily separated by the very large, strongly punctured tegulse;the much lighter wings; and the hair at apex of abdomen all pale(much black in lamarensis) . The coarsely punctured abdomen sepa-rates it at once from the similar species of Xanthidium.Habitat.?Texas (Belfrage).Type.?Cat. No. 13427, U.S.N.M.NOMADA MACULIFRONS, var.

Especially characteristic of the species is the large,smooth and shining yellow mark on each side of face. Structural char-acters, not mentioned by Smith, are as follows: Mandibles simple;third antennal joint shorter than fourth, though both are quite long;tegulse rather large, well punctured; area of metathorax rugosebasally; wings long; h. n. going far basad of t. m.; second s. m.receiving first r. n. before middle; abdomen very finely punctured;crescentic apical patch rather large. The femora, tibias, and tarsiare entirely red, except that the hind femora have a blackish streakbehind. The tubercles are prominent, yellow margined with red, andthe upper border of the prothorax is yellow, red at each side. Thereis a very large red patch on the pleura. This is perhaps a distinctspecies, but as it is evidently close to N. maculifrons, and I have notbeen able to compare specimens ; I leave it for the present as a variety.The abdomen, in its color and pattern, shows a strong superficialresemblance to that of N. ruficornis Linnaeus, variety, from Jena;but in the ruficornis the yellow spot on the third segment is sublateralinstead of lateral, and there is no yellow spot laterad of the band onthe fourth. In Schmiedeknecht's table of European species it runsto 52, and runs out because the yellow spots on scutellum are sepa-rated, and the hind tibial apical spinules are red.

Japan, No. 163.Type.?Cut. No. 13429, U.S.N.M.I first compared this insect with the Old World Nomadse, in mycollection, and concluded that it was very close to N. ruficornis(Linnaeus). I then ran it in Schmiedeknecht's tables of EuropeanNomada, and found that the male ran directly to ruficornis; the femaleless certainly, but still better there than anywhere else. It is wellknown that N. ruficornis is exceedingly polymorphic, and while theJapanese insect may be specifically distinct, and perhaps the var. ais another species, it seems best to treat the scanty material at presentavailable as a subspecies only. On the whole, it evidently comesnearest to the northern variety glabella Thomson. The male is verylike the American N. illinoensis Robertson. NO. 1806.

This fine specieslooks exactly like N. vallesina Cockerell, except that it is largerand more robust. The following differences appear on minute com-parison:Inner orbits almost parallel; third antennal joint longer; anterior coxse with a rudi-mentary spine; scutellum slightly bigibbous; apical part of flagellum darkened;cheeks entirely red; tegulse large N. libata.Inner orbits diverging above; third antennal joint shorter; scutellum strongly bigib-bous; apical part of flagellum red like the rest; posterior part- of cheeks black;tegulae ordinary iV. vallesina.NOMADA SEMISCITA Cockerell.A male from Denver, May 26, 1898, has a short broad supra-clypeal mark in the manner of N. martinella and scita. The speciesdiffers from these by the comparatively short and thick fourthantennal joint (in martinella this joint is quite long and excavatedon the outer side), the fifth joint with a prominent thorn-like spine,the second s. m. receiving the first r. n. at the middle (beyond inmartinella), the postscutellum entirely black, the two light markson the first abdominal segment each inclosing a ferruginous spot.In the new specimen the apical plate of the abdomen is stronglynotched. This is perhaps the male of N. frieseana.NOMADA SCITA Cresson.Males are from Denver, Colorado, May 26, 1898; Colorado, 2076(Baker collection), and Los Pinos, Colorado, at Erigeron May 22, 1899.This is smaller than male N. martinella, but on comparing a seriesthe supposed differential characters seem evanescent and I am notaltogether satisfied that the two species are distinct. The femaleof N. scita has not been described, but one was taken by Baker atLos Pinos, Colorado, on Erigeron, May 22, 1899. It is smaller anddarker than .V. martinella, but otherwise similar. Comparison wasmade with the usual Colorado martinella; but the true type of thatspecies from New Mexico was small, though clear bright red.NOMADA MARTINELLA Cockerell.The U. S.

In both species there is a semi-circular finely white-tomentose area at the end of the abdomen.Male.?Length about 4^ mm.; resembling N. grindelix, but muchsmaller, with the abdomen variably suffused with reddish at theapices of the first two segments.Habitat.?Victoria, Texas, at flowers of Helenium tenuifolium'Nuttall,September 26, 1904 (J. C. Crawford). Four males and three femalesare before me, and as the small size is uniform, I think the speciesmust be considered distinct. Mr. S. A. Rohwer had already recog-nized it as new. There is some question whether Melanomada shouldnot stand as a distinct genus. Mr. J. C. Crawford examined themouth-parts of N. grindelise, and found that the maxillary palpi hadjoints 3 to 5 subequal, 6 longer; joint 2 about equal to 3 + 4; joint 1shortest. He pointed out that the development of joint 2 wascharacteristic.Type.?Csit. No. 13431, U.S.N.M.There is a rather close resemblance between Melanomada andViereckella. Doctor Graenicher has sent me both sexes of VierecJcellapilosula (Nomada pilosula Cresson) from Milwaukee, Wisconsin,where it flies in July and August. Both sexes have the abdomenblack, resembling the male of Melanomada. The males are separableby several good characters, as follows:Face broad, inner orbits parallel; venation ordinary for Nomada, second s. m. receivingfirst r. n. well before end, third s. m. narrow above; legs ordinary; apical plateof abdomen broad, rounded, broadest at base Melanomada.Inner orbits strongly converging above, so that the lateral ocelli are distant from eyesless than their own diameter; second s. m. receiving first r. n. very near end, third s. m. very broad above; middle and hind femora incrassate; apical plate of abdomenspoon-like, narrower toward base Viereckella.The type of N. Jieleniella is a female.NOMADA WHEELERI ENGELMANNI^, new subspecies.Female.?Length 7^ to 9 mm,, agreeing with the description ofN. wheeleri except as follows: Light markings cream-color; red linealong anterior orbits interrupted in frontal region; mesothorax witha broad black band, and the red in front deeply emarginate on eachside; light color of scutellum narrowed but not divided in middle;pleura red, broadly margined, except below, with black, and withno yellow spot; wings more dusky, the broad apical margin dark;first abdominal segment with the basal half black; second and thirdsegments with much black at base, band on second narrowly orbroadly interrupted, but always extremely broad laterally. 650 PROCEEDINGS OF THE NATIONAL MUSEUM. vol.39. Habitat.?Dallas, Texas, May 22, 1906, at flowers of Engelmanniapinnatijida Torrey and Gray (W. S. Pierce) ; also one from Dallas,May 17, 1908 (F. C. Bishopp). Perhaps a distinct species, but cer-tainly very close to N. wheeleri, which is known from a single speci-men. These species fall in a little group, in which the coxal spinesare not distinctly developed, and yet the insects accord in generalwith the subgenus Micronomada.Type.?Csit. No. 13432, U.S.N.M.The following key contrasts the members of this group : Mesothorax at least largely red (Texas) 1.Mesothorax black without red 2.1.

Markings yellow (Virginia) mimula Cockerell.Markings creamy-white (Washington State) jennei Cockerell.Since the above was written I have examined two males of N.wheeleri engelmannix collected by Mr. C. L. Marlatt in Riley County,Kansas, September. They have the following distinctive characters : Length about 9^ mm.; coxal spines absent; face light lemon yellowup to level of antennse, the lateral face marks extending obliquelyupward laterally, ending in a sharp point on orbital margin nearlevel of middle of scape; supraclypeal mark square; labrum, andbase of mandibles broadly, pale yellow; posterior orbital marginnarrowly pale yellow ; scape greatly swollen, entirely hrigJit ferrugi-nous red; flagellum darker red; third antennal joint much longerthan fourth; mesothorax very densely punctured, entirely black;metathorax black, with a small red spot on each side; upper bor-der of prothorax, tubercles, tegulse, scutellum, and postscutellumcream-color; pleura with a very large red patch, inclosmg a variableyellow one; legs red, hind coxae with a large whitish spot; abdomenlike that of female; apical plate broad and rounded, with a feeblyindicated notch. Some one had labeled this ^'heilighrodtii Cresson ? ".It is entirely different from the described male of heilighrodtii, which(according to Viereck, who examined the type for me) has a slenderscape. I have long thought that the described male of heilighrodtiidid not truly belong with the female, but the female of the presentinsect is known, and is quite distinct from heilighrodtii.NOMADA RUBICUNDA Olivier.Liberty, Texas, 2 females, March 18, 1908 (E.

The specimens from Texas have a slightlydifferent aspect, but after careful comparison I can not find anycharacters on which to separate another species. The insect lookslike a small N. texana, but the mesothorax is shining, with wellseparated punctures. The Texan variety may be distinguished bythe yellow markings of the head and thorax (varying in depth ofcolor), those of the New Mexico type being ivory color.Falfurrias, Texas, at flowers of Helianthus, May 18, 1907 (A.

The male is larger than the original type(fully 11 mm. long), and the black is much reduced, on the headto the ocellar area, on the thorax to a slight stain along the anterioredge of the mesothorax. All the tibiae are marked with yellow.These differences are apparently not racial. The female looks likethe male, but the face is all red, with a shght yellowish suffusion oneach side. The legs show less yellow.NOMADA TEXANA Cresson.According to the material before me, this is by far the mostabundant Nomada in Texas.

NOMADA TEXANA CRUCIS (Cockerell).Nomada crucis was described in 1903 as a doubtful subspecies ofN. texana, based on the smaller size and coarser sculpture of the'metathorax. As it occurs in southern New Mexico itappears sufficiently distinct from typical N. texana ofeast-central Texas, but the abundant material nowbefore me clearly shows intergradation in south-centralTexas, north of the Rio Grande. I give a figure of thegenitalia of N. crucis fi'om Devils River. I also pre-pared a slide of the genitalia of quite typical texanafrom Piano, and so far as I can see there is no essentialdifference. As we go down the valley of the RioGrande, practically normal N. crucis is found to bemixed with larger individuals, which can be regardedas rather small texana. The females lead in this in-crease of size, but in humid Texas both sexes are of full genitalia of male? 1, / PI Nomada Texanatexana size, and even at CotuUa (10 males 6 females crucis.examined) this is the case, with rare exceptions. It isnot unlikely that crucis is largely or even wholly an environmentalproduct, not gametically different from true texana.A single male crucis (here a mutant or dwarf of texana?) comesfrom Ardmore, Indian Territory, August 18 (Bishopp).
