J '3: 149 THE AMERICAN BEES OF THE GENUS ANDRENA DE-SCRIBED BY F . SMITH. BY REV. F. D. MORICE AND T. D. A. COCKtsRELL. ( Continued from page I 24.) A11dre11a.fragilis, Srriith, r853. "This I suspect is the ci of integra; area similarly strigose, and abdomen also corresponds; tubercle matches also!" Robertson thought this might be A. platypari,i : but, he said, the description applied even better to salicis, and nearly as well to mandibularis. It cannot well be salicis, as that has the abdomen impunctate; if it is the 6 of integra, it cannot well be 111a11dib1tlaris; it may perhaps be platyparia. And1·ena .frigida, Smith, 18 53. "(Very near apicata, but hairs of thorax much darker) ? = lapponica; antennre with very long third joint; tubercle n; area granulated; abdomen in style of apicata." Type locality, Nova Scotia. I do not know any similar species. Andrena ft111b1·iata, Smith, 1853 ( Americana, D. T.). " 6 abdomen rugulose and punctured, clothed with long adpressed hairs; tubercle slightly emarginate (?); area dull granu lose; <j? ditto. (Very near .fuscipes, perhaps identical with it.)" This agrees with what I had already identified from Smith's description. It seems to argree with the description of A. simillima, Sm., even better than with that of .fuscipes, but I doubt its actual identity with either. A11drena ltirticeps, Smith, 1853. ;J. "Tubercle pointed apparently, hard to see under thick bush of hair on clypeus; area obliquely rugose at base on ly, no raised margin ; abdomen tessellate, practically impunctate; apical ventral valve somewhat bilobed; antenna! with article 3 = 4 + 5 about, all joints pretty long. Has a good deal the aspect of gwyna11a." This was considered the J of A. vici11a, but Robertson (1900) has come to regard it as a valid species. He further adds: "But for the description of the 6 , I would say lhat A . errans is the same as A. /1irticeps." I have an Illinois "ltirticeps," J, from Mr. Robert-son, and the abdomen is distinctly punctate at the bases of the hairs, while the third antenna] joint is barely longer than the fifth, the fourth being a little shorter than either. The apical ventral :\lay. 1001. 150 THE CANADIAN ENTOMOLOGIST. - ---- --------------- ------- --- -valve also is not bi lobed. In the female of Robertson's "liirticeps," the basal process of labrum is low, broad and rounded (semi-circular, Robertson expresses it), which does not agree with vici1ta or errans. Robertson's insect will therefore need a new name, as follows: Andrena Carli1ti, n. n., Ckll. Aitdrena bicolor (not of Fab.), Rob., Tr. Am. Ent. Soc., XVIII., 5 r. Andrena vicina (not of Sm.), Rob., Tr. Am. Ent. Soc., XXII., 118. Andrena !tirticeps (not of Sm.), Rob., Trans. Acad. Sci., St. Louis, x., 47. The true A. !tirticeps is a northern species, from Hudson's Bay. A. Cai-lini is from Illinois ; type locality, Carlinville. It also occurs in Kansas, N. Y. and N. M. (see below). Andrena algida, Smith, 1853. d'. "Tubercle truncate; apical ventral valve o; antenna! Jomt 3 about = 5, slightly longer than 4; area (longitudinally) somewhat rugose ; abdomen tessellate and also delicately punctured." Type locality, Hudson's Bay. The 6 is rather suggestive of Carlini, except as to the tubercle. The ~ described by Smith is not at all like Carlini. A11drena itztbecula, Smith, 1853. ~ . "Tubercle emarginate ; area shortiy rugose at base ; abdomen tessellated, impunctate; a pretty insect, with broad white bands and pale reddish-yellow apex; antenna! article 3 scarcely = 4 + 5 (cf. proxima or dorsata)." "Wings remarkably clouded." I have this from Lincoln, Nebraska, collected in August and September, sent by Prof L. Bruner (No. 12). Smith's description of the abdomen is inaccurate as regards the punctuation. A1tdre11a obscuripe1mis, Smith, 1853. ~. "Tubercle convexly truncate; abdomen closely punctured ; area bordered with raised ridge, rugose but not very largely so, and laterally only granulated; wings beautiful violet; pilosity rich red (large grand species)." Type locality, Georgia. This has some resemblance to A. Hallii, but is quite distinct. Andreita pe1plexa, Smith, 1853. ~. '' Tubercle truncate ; area seems nearly smooth, but dull, with fine close tessellations ; abdominal segments smooth and closely punctured, except towards their apices, which are rugulose." Type THE CANADIAN ENTOMOLOGIST. 151 locality, Georgia. This is evidently different from any species I have seen. Andrena 11ivalis, Smith, 1853. 9. "Tubercle /-\ ; antenna] joint 3 longer than 4 + 5 ; area rugose at base; abdomen distinctly punctured, but on an aciculated surface." Type locality, Hudson's Bay. This is very near to A. semirzifa, Ckll., from New Mexico; possibly it is the same species. A1tdrena !tilaris, Smith, 1853. 9. "Tubercle of labrum wide, truncate, below its centre a projecting pencil of golden hairs; clypeus ,coarsely punctured, with a smooth shining carina down its middle ; metathoracic area finely rugulose, with some coarse short longitudinal strig re at its base ; abdomen distinctly punctured, its surface also microscopically (hard ly visibly) rugulose; wings very yellow.'' Type locality, Georgia. Evidently distinct from anything I have before me. Andrena vici11a, Smith, 1853. ~. Length "about r 4 mill.; tubercle wide, truncate; clypeus with wide unpunctured central elevation; area dull rugulose; abdomen finely rugulose all over, and distinctly but shallowly punctured." Smith gives the length as only 5 lines, and says the species closely resembles A. 11itida. I hardly know what to make of this ; the species referred to vicina in American collections has the tubercle low and rounded, by no means truncate; also, it does not have the very shiny, oval abdomen of nitida, which species, it may be remarked, has the tubercle concavely truncate. A. vici11a is said to be from the United States and Nova Scotia. Andrenaplacida, Smith, 1853. 9. " Tubercle very narrowly truncated; area rather coarsely rugulose, but not margined, I think; abdomen ~ugulose, a few sparse punc-tures ; length about 12 mill., much smaller and narrower insect than vicina- 1ooks like a parviceps." From "U. S." Smith gives the size the same as that of vicina, but this must be a mistake. A. placida seems to come close to A. Macgillivrayi. Andrena.fastuosa, Smith, 1879. 9. "Tubercle 1-\ , difficult to say if actually emarginate; area and abdomen as J . " t. "Tubercle emarginate; huge stipites ! area rugose, unmargined; abdomen closely punctured." From Orizaba, Mexico. A11drena 152 THE CANADIAN ENTOMOLOGIST. argemo11is, Ckll., from New Mexico, is possibly not separable from .fastuosa. A11drma discreta, Smith, 1879. Cj' • "Co loured like a big bright cetii; tubercle emarginate ; area finely rugose, unmargined ; abdomi nal segments densely clothed above with fulvous hairs, except the basal which is naked." Oajaca, Mexico. When de~cribing A. jessicre I suggested that it might possibly be the J of discreta, but it is now evident that this cannot be. A11dre11a sodalis, Smith, 1879. "Tubercle ,---,. ; abdomen shining, though rugulose, and also very delicately punctured; area not margined nor rugose." Oajaca, Mexico. Andrena simulata, Smith, 1879. "Labrum almost pointed fl, I see no definite tubercle; abdo men smooth, very shining, shallowly punctured ; area without ridge, rugosities slight, longitudinal at base." Orizaba, Mexico. A1tdretta agilis, Smith, I 879. 6 . " Labrum looks truncate , I can't see tubercle; clypeus not all white, but marked with yellow like a Cj' Ceratina; abdomen finely punctured ; area rngulose, not clearly defined at sides; central impression deep?" Oajaca, Mexico. Andrena modesta, Smith, 1879. Cj'. "Sides of propodeum fringed with short white hairs; area rugulose, not margined; abdomen finely punctured; no tubercle to be seen." Oajaca, Mexico. Aitdretta commoda, Smith, 1879. Cj'. "Tubercle pointed /\ ; area not margined, fine basal strigre; abdomen punctured, also aciculate, dull." This nearly agrees with A. pnmi, Rob., but the tubercle of that species is not at all pointed. A. com11toda is from Canada. Andrenajlavoclypeata, Smith, 1879. 6 . " Clypeus has a t!tird black spot in middle of apex ; tubercle hard to see through hairs, I think a little emarginate; area not ridged; abdomen tessellated, scarcely punctured." Loca lity, Canada . This is regarded as a synonym of A. bijnmctata, Cresson, and 1s well known. The third black spot is not always present. THE CANA.l)IAN ENTOMOLOGIST. 153 Audrena miranda, Smith, 'i879. 0 'il. "Clypeus /-\ ; area coarsely clathrate and margined; abdomen strongly punctured." Canada. Related to A. Forbesii, but not the same. A11dre1ta vuesta, Smith, 1879. "Area scarcely ruguiJ&e, not margined; abdomen scarcely punctured ( lapponica style); tub ercle slightly emarginate or bilobed. Canada. This species appears to differ from any known to me. A11dre1ta errans, Smith, 1879. "Area not margined, smooth nearly ; abdomen with shallow punc-tures ; tubercle pointed ( one 'il has the discs of abdominal segments densely clothed with black upright hairs, probably a different species)." Vancouver I. • This is not the north-western species which I have regarded as errans; the female with hairy abdomen may be pluvialis. A close study shows that there are several species confused with viciua or erra11s in American collections. These ( 'il) all agree in being about 13 or q. mm. long; the thorax densely clothed with upright rather short hair (bright ferruginous in Hal/ii, pale ochraceous in the rest); the abdomen shining black, without hair-bands; the anal fimbria black ; the wings decidedly brownish. The species of this series now before me are : A. Carlini, Ckll.: Tubercle of labrum broad and evenly rounded; clypeus with a median impunctate ridge; hair of face mixed pale and black, of pleura black ; basal area of metathorax roughened, not plicate; abdomen tessellate and well punctured; antenna! joint 3 rather shorter than in Hal/ii. Illinois; Beulah, N. M., May 30 ( vV. Porter); Baldwin, Kansas, May (J. C. Bridwell} ; Ithaca, N. Y., May 17 ( lJfacgillivr ay). Seven specimens ex-amined. A. Hal/ii, Dunning: Tubercle of Jabrum broad but truncate ; median line of clypeus impunctate, but minutely tessellate; hair of face and pleura black; basal area of metathorax obliquely plicatu-Jate at base; abdomen tessellate, with numerous small punctures. Pullman, Wash. (C. V. Piper). A. cupreoti11cta, Ckll., n. sp.: Tubercle with sloping sides and truncate apex ; clypeus without a median impunctate ridge, or it is very short and rudimentary; hair of face, cheeks, occiput and 154 THE CANADIAN ENTOMOLOGIST. pleura black; basal area of met a thorax strongly longitudinally plicate, its sculpture entirely different from that of the adjacent lateral areas, though it has no raised margin ; abdomen well punctured on a smooth surface, the punctures very strong and close at the sides of the segmei1ts; hair on inner sides of basal joints of tarsi tinged with coppery. Skokomish River, Wash., April 26, 1892 (Trevor Kincaid). A. pluvialis, Ckll., n. sp.: Tubercle with sloping sides and truncate apex; clypeus without any impunctate line; hair of face black , a little pale at sides, of vertex and cheeks black, of occiput pale, of pleura black; area roughened,not plicate,longer than in cupreoti1tcta, and so larger, larger than in Carlini because broader behind, its posterior angle greater; abdomen with a sericeous lustre, the punctures small; surface of abdomen quite hairy, the hairs black. Olympia, Wash., May 1, 1894 (Trevor Kincaid). A. anogrre, Ckll.,n. sp.: Agrees withpluvial is, except that pubescence of thoracic dorsum is brighter, more fulvous; hair of face is wholly black; tubercle is small and emarginate or binodulose at apex; area is more coarsely rugulose and much narrower behind, being shaped as in Carl£11i. Colorado Springs, Colo., middle of July, at flowers ofa white CEnot/t(lra (Ckll., 3567). A. vicina, Smith : Tubercle broad and truncate, the truncation sometimes concave and distinct, sometimes rather obscure ; clypeus with a median impunctate ridge, which is more or less roughened ; hair of face pale, black only round the mouth, or only below the mouth; hair of cheeks, vertex, occiput and pleura pale, area rough-ened, large, not narrower behind, shaped as in pluvialis, but the sides of the metathorax are clothed with pale hair, whereas in pluvialis it is black; abdomen tessellate and well punctured, hardly hairy except apically, being much less hairy than in pluvialis; hair on first segment pale. Olympia, Wash., June 41 1895 ( Trevor K£11caJd); Michigan ( C. F. Baker, labeled A. bicolor); Hartford, Ct., May 30, 1894, and May 31st, 1896 (S. N. Dzmni11g). This is evidently the true vici11a of Smith ; it ranges further north than Carlini. A11drena crerulea, Smith, 1879. "Area smooth, not margined ; abdomen rugulose with slight raised points; tubercle I think slightly emarginate." Vancouver I. A. THE CANADIAN ENTOMOLOGIST. 155 ccerulea, var. territa, Ck!!., Entom., 1898, p. 89, is perhaps a distinct species; in the description, line 15.from top of page, tinge is mis-printed "fringe." A. 1tigroccer1tlea, from the same region, has the tubercle concavely truncate, one might say slightly emarginate, but it is otherwise different from ccernlea. A1tdrma subtilis, Smith, 1879. "Tubercle A; abdomen tessellated , hardly punctured; area smooth, not ridged laterally." Vancouver I. I do not know this species. Andrena candida, Smith, 1879. "Abdomen dull green, scarcely punctured ; area with rugosities slight, no ridge; labrnm ? a little emarginate." Vancouver I.; Olympia, Wash., June 18, r895 (Trevor Kincaid). In Mr. Kincaid's specimen the hair at apex of abdomen is blackish, but the species ts doubtless the same. A. geranii, Rob., is closely allied. A1tdre11a auricoma, Smith, 1879. "Can't see labrum; a pretty insect with fulvous upright pilosity on discs of segments and golden fascire at the apices; area granulose, not margined. " Vancouver I. Unknown to me. BOOK NOTICE. REPORT OF INJURIOUS INSECTS and Common Farm Pests during the year 1900, with Methods of Prevention and Remedy. By Eleanor A. Ormerod, LL.D. London: Simpkin, Marshall & Co., 1901 (1s. 6d.; pp. III), It is with deep regret that we learn from the preface of this her twenty-fourth annual report that the talented authoress has decided that it shall be the last. For almost a quarter of a century Miss Ormerod has labored hard and well in the service of her country, without any remuner-ation and with scanty recognition from the officials who should have been the first to express their gratitude to her. But, on the other hand, she has won for herself a high reputation in Great Britain, in America, in South Africa and Australia, and also in several European countries. She is known far and wide as a painstaking entomologist, a keen observer, a diligent collector of facts and observations, a thoroughly practical and sensible adviser, and one who has been all through these years most unselfish in placing her time and her work at the disposal of those who needed them most-the farmers and gardeners of her native land,
