42 Psyche [April
last third; second r. n, joining third t. c. Face and front brilliant green, the mid- die of the clypeus and supraclypeal area strongly flushed with crimson, the sides of the face with golden; mandibles black; vertex and cheeks a sort of dark copper color, with black hair; antennae black, flagellum dark reddish beneath; prothorax dark coppery, with black hair; pleura dark purple, with dark hair showing reddish in favorable lights; nearly the anterior half of mesothorax brilliant green, with thin ferruginous hair, the posterior part, and the scutellum black (slightly brassy), with black hair; abdomen clear yellowish-green, with short ferruginous hair, becom- ing whitish apically, the basal segment with black hair at sides toward base; no \
bands o~ abdomen; apex of abdomen bituberculate; ventral surface of abdomen with segments 3 to 5 green, the others dark; tegulae large, pointed posteriorly, ante- riorly with a large green patch; wings strongly dusky, reddish; legs black, ante- rior tibiae purple in front; middle tibiae bronzy behind, in front flattened, dull and without punctures, suffused with carmine, except at apex, where they are bright blue-green; middle basitarsi densely covered on outer side with shining yellowish- white hair; hind basitarsi smooth and concave on outer side, on inner covered with black hair.
Hub.-Abuna, on the Rio Madeira, Brazil (Mann & Baker). A magnificent species, but superficially, when seen from behind,, looking exactly like the common E. mussitans (Fabr.). It may also be compared with E. superba (Hoffm.), to the vicinity of which it runs in Ducke's table. E. manni will be especially known by its mussitans-like appearance, bicolored mesothorax, total absence of a median keel or clypeus, small size of the prominences above the spurs of hind tibiae, and first abdominal segment colored like the rest. The coloration resembles that of E. fallax Smith, but that species has a central keel on the clypeus. Xylocopa branneri sp. nov.
Female.
Length 21 mm., anterior wing 16 mm.; exactly like X. grisescens Lep., but much smaller, with hair on sides of thorax all black. Abdomen beneath with
a median raised line; clypeus smooth in middle except apically, lateral margins strongly elevated; labrum tridendate; wings dark, with bluish green and purple tints. Hub.-Natal, State of Rio Grande do Norte, Brazil (W. M. Mann).
Named after Dr. J. C. Branner, leader of the expedition. Centris (Hemisia) bakeri sp. nov.
Male.
Length about 13 mm., anterior wing 11; head and thorax black, with fulvous pubescence above, white below, and on cheeks and occiput, hairs of middle of vertex stained with fuscous; face narrow, eyes diverging below; clypeus strongly raised, with a broad flattened face, the sides of which are sparsely punctured; scape

and middle tibiae, and long stripe on anterior tibiae, yellow; hair of legs mostly pale, black on hind tibiae except a large tuft posteriorly on apical half, on hind basitarsi reddish-black without and dark red within, but pale and strongly plumose poste- riorly; hair on inner side of anterior and middle tarsi red; abdomen short and broad, dark metallic green, with the apical margin and sides of fourth segment, and the whole of fifth to seventh, clear red, a reddish suffusion also at sides of second and third apically; second and third segments each with large lateral yellow patches, that on the second much the largest, subquadrate; first abdominal segment, except at apex, and fourth and following segments, with pale hair; apex of first, and sec- ond and third, with thin short black hair, only visible in lateral view; venter with abundant pale reddish hair.
Hob.-Rio Madeira, Brazil; Madeira-Mamore R. R. Co. Camp 43 (Mann & Baker). This is 325 km. from Porto Velho. C. bakeri
is a species of the C. versicolor group, recognizable by the yellow patches on the sides of the abdomen. C. haemorrhoidalis (Fb.) has a yellow spot on each side of the second abdominal segment, but the abdomen is quite a different color, and the thorax is dark- haired.
The three species of Hemisia in the collection are separable thus: Wings bicolored, very dark, with broadly pallid apical field; hair of ver- tex ( $ ) black. .......................................... maculata Lep. Wings not bicolored. ................................................. .1 Abdomen yellowish-green, the hind margins of the segments pallid, but the apex not red; cream-colored spots at sides of segments 2-5, that on 2 a mere dot. ...................................... .oenea Lep. Abdomen dark green, red apically; yellow patches on sides of second segment very large. ........................................ bakeri Ckll. Centris (Ptilotopus) heterodonta sp. nov. Female. Very robust; length about 19 mm., anterior wing about 12; black, the legs and the end of the abdomen red; hair of head and thorax fulvous, without black or fuscous, paler beneath, becoming dull white on lower part of cheeks; scape thick, yellow in front; flagellum dark, ferruginous at extreme apex; clypeus convex with a large median cup-shaped black area, on which is a longitudinal yellow band, this band smooth and shining, but the black space on each side of it dull, with

mttered strong puincturea;
very broad anterohteral areas of &pew yellow, as also arq the lateral face-marks, which are trianguiar, the upper edge nearly straight. but with a linear process extending a short way up orbital margin; l~bm pale yellow, broad, but with 8 median apical spine, which is dark reddish; no supra- clypl mark malar space dark reddish; mandibles strongly curved, very broadly yellow basally, apically broadly red on outer aide, teeth four, two apical, one about twice as long as the other (inner one), one broadly truncate and subemargkiate on the inner side neat the middle, and a short angular one at the base of that; lower part of sides of prothorn red; truncation of meta-thorax with a large whitish patch on each side; tegutie light tmuginous; wings strongly dusky, marginal cell smoky, strongly appendiculate, the area above the appendicular nervure f uligutotu; ante- rior and middle tibb with a yellow spot at base, and indications ol a stripe on ante- rior pair; hair of legs bright fmuginous, cream-colored on anterior legs behind; Bcopa of hind tibife and basitarsus very large, strongly plumose, a vwy fine coppery [red; abdomen with the first three segments black above, the hind margins of aw- ond and third dark red, the remaining segments red, the fourth dark basally; first segment with pale fulvous hair; second and third with very short inconspicuous Hack hair, the others with red hair; venter fermginoua; apical pfate truncate. Hob.-Porto Velho, Rio Madeira, Brazil (Mann <fe Baker). A very fine species, not close to any known to me. It is placed in Ptihtopus, but in spite of its lack of metallic color, it is doubtless allied to the species of HmWla.
In Friese's table of Melanocen-
iris (Ptilotopus) it runs to 22, and except for its rather smaller size, on to the vicinity of fuscata or jumkttnS, which it does not re- semble. In the table of species with red abdomen it cannot be made to fit anywhere.
It cannot be run to anything in Schrottky's tables of Brazilian or Paraguayan species. Centris (Pfiteopi") libmatis sp. nov.
Female. Length about 11$ mm.; black, the head and thorax with fulvous pub- escence, becoming whip beneath, fuscous on vertex; clypew much broader than long, rugose, with a longitudinal keel, a median trianguinr area black, the apex of the triangle downwards, the lateral areas, almost meeting below, yellow; a nar- rowly crescentic suptaclypeal mark, lateral face-marks filling space between dy- pews and orbit and sending a narrow band up orbital mar& beyond level of an- tennse, lab- entirely, and more than 'basal halt of mandibles, all lemon-yellow; mandibles rather slender, not dentate; eyes yellowish-green; antenn~ short, black, first joint of flsgelhim elongated; mesoth&rax and acutelturn densely punctured; a #lender hairless line along hinder middle of mesothorax, but no other bare apace; tfegulte closely and minutely punctured, ferruginous, with broad whitish margin; wings strongly infuscated, nemirea piceous, very heavy; the three submarghal cells about equdy long Wow, the mnd broader t h high, little pduced at upper apical corner, receiving first r. n. about middle; marginal d l short, with a ful-

iginous streak at base; legs black, the middle and anterior tibiae with a yellow spot at base; hair of legs black, in part very dark fuscous, thin and yellowish-white on outer side of anterior tibiae, and a fringe of the same color on their femora; scopa of hind legs black, large and very coarse; abdomen black, moderately shining, with short black hair, the first segment without pale hair, but that of the fifth thin and white (best seen in lateral view), with an apical chocolate-colored fringe, and long chocolate hairs on each side of apical plate; beneath, the fourth segment has a con- spicuous fringe of light hair.
Hab.-Independencia, Parahyba, Brazil (Mann & Heath). At
first sight this seems a most ordinary little species, just like several of the nitida group. On closer examination, it appears not to be a typical Centris, by reason of the venation, which in Schrottky's table of Brazilian genera, would throw it out of Centris altogether. It is however actually allied to some of the nitida series, especially perhaps to C. birkmanni; Friese, which however has a much shorter first s. m., and the clypeus entirely black in the females. Centris ceratocephala sp. nov.
Female. Length about 14 mm., unusually long and slender for a Centris, head and thorax black, abdomen bright red; legs red, the anterior ones, and the middle tibiae, suffused with black. Very close to C. bicornuta Mocsary, having the same peculiar structure, but larger; the shining clypeus black with a triangular yellow mark on each side; wings dusky, but not dark; abdomen with the first segment suffused with blackish, but its hair all pale fulvous; second and third segments bare, fourth with fuscous hair, fifth with fulvous; scopa of hind legs entirely light fulvo- ferruginous. There is much black hair on the head above, both before and behind the ocelli. Mandibles bidentate; labrum longer than broad, black with two very large elongate yellow patches, which nearly meet in the middle line below, apex strongly bidentate, lateral margins obtusely angulate near the middle; teeth at sides of apex of clypeus long, black, cylindrical. Eyes dark brown. Hair of thorax
above fulvo-ferruginous, without any dark. Hob.-Manaos, Brazil (Mann & Baker). Possibly a subspecies of C. bicornuta.
Manaos is more than a thousand miles from the type locality of bicornuta.
Dianthidium heathi sp. nov.
Male. Length about 5 mm.; head and thorax strongly and densely punctured; clypeus, mandibles except apex, broad bands along inner orbits and two long narrow .
bands passing just mesad of antenna1 sockets, all pale yellow; scape ferruginous; a continuous orange band across occipital region; mesothorax with very large punc- tures, black with somewhat more than the lateral thirds of the anterior margin broadly yellow; a broad yellow band from axillae across scutellum, narrowly inter-

rupted in middle; legs reddish, blackish and yellow, the anterior femora and tibiae broadly striped with yellow; tegulae deep ferruginous, with an orange spot; mar- ginal cell and apical part of wing dark fuliginous; abdomen black, with very broad oblique orange bands, widely separated in middle, on first segment, on second a nar- rowly pear-shaped yellow mark on each extreme side, on third a narrow yellow band on each side ending mesad in a very large elongate club, on fourth to sixth entire bands, that on sixth notched in front; seventh segment cream-color, the lateral cor- ners with long straight spines, the truncate ends of which are dark, while in the mid- dle is a very slight prominence. So close to D. gregarium (Hypanthidium gregarium Schrottky) that I had considered it identical, until I noted the antennae, which is heathi are long but quite normal, the flagellum slender but not crenulate, dark above, ferruginous below, whereas in gregarium the flagellum is very long, strongly crenu- late below, each joint light ferruginous with the base black, but the last entirely black; the armature of the apex of the abdomen is quite the same in both. These forms have pulvilli, and represent an aberrant section of Dianthidium. Hab.-Independencia, Parahyba, Brazil (type locality), 3 males (Mann and Heath) ;
Natal, Brazil, one male (W. M. Mann). The D. gregarium compared is from Villa Encarnacion, Paraguay, col- lected by Schrottky. An apparently allied species is Anthidium pygmceum Friese, known only in the female. Judging from Friese's description, our species is too different from pygmceum to be its male.
Ceratina chrysocephala sp. nov.
Female. Length about 94 mm.; head and thorax very strongly and coarsely punctured, golden-green, the head with golden tints, the mesothorax with crimson, the posterior disc of mesothorax with a smooth dark area; pubescence very scanty, thin and white on pleura and sides of metathorax; mandibles and labrum entirely black; clypeus dull in the middle, and with large punctures, the lower margin with a very broad transverse orange band, not reaching lateral corners; lateral face- marks orange bands, very broad below, rather irregular on inner side, ending above at about level of antennae; posterior orbits with broad orange bands, the upper part leaving the orbit; antennae red as far as fourth or fifth joint, darkpiceous or black beyond; scutellum closely punctured, roughly granular posteriorly; tubercles green; tegulae dark chestnut;
wings deep fuliginous, with violet tints; legs more or less green; anterior tibiae with a yellow stripe, connecting with a spot at apex of femur; middle tibiae with a yellow basal spot, hind tibiae ferruginous at base; hind tibiae with much white hair; middle femora conspicuously angled beneath toward base; abdomen shining dark bluish-green, with slight brassy tints, strongly punc- tured; sixth ventral segment subcarinate. Hob.-Manaos, Brazil (Mann & Baker). In Schrottky's table of Brazilian species this runs to the vicinity of C. longiceps Sm. and cupriventris Sm. The shape of the head is not at all as in

longiceps, while the colors and markings disagree with cupriventris. In Schrottky's later table (Zeits. Hym. Dipt., 1907, p. 480) this runs to C. gossypii Schrottky, which really seems to be closely allied, but in gossypii the pleura is finely punctured, the scutellum is blue-green, and there are various other differences. Compari- son with other recent descriptions does not indicate identity in any case.
Ceratina manni sp. nov.
Female.
Length about 4$ mm.; dark but shining bluish-green, the apical half of the abdomen roughened; sides of front hardly punctured; a large broad elongate (vertical) mark on clypeus, a small broad-oval mark on each side of it, a broad elon- gate mark (like that on clypeus, but smaller) along each anterior orbit opposite antennae, and a stripe on each cheek (receding from orbit) all ivory-white; mandi- bles and labrum dark, the labrum and apical half of mandibles obscurely reddish; antennae black basally, the thick flagellum light ferruginous below, dark rufopi- ceous above; tubercles broadly white margined; tegulse dark reddish; wings dusky. The mouthparts are not greatly elongated. Tarsi dusky reddish; anterior tibiae with a pale stripe.
(In C. lucidula the legs are pale testaceous.) Hob.-Independencia, Parahyba, Brazil, 6 females (Mann & Heath). This little species resembles C. nautlana Ckll., but is at once distinguished by the five light marks on face. It also resem- bles, on account of its small size, C. lucidula Sm., muelleri Friese, gossypii Schrottky, and minima Friese, but it will not agree with any of them. Ducke says that muelleri is the same as lucidula, but the legs are quite differently colored. C. minima is known only in the male, but I am confident that manni is not its female. Melipona pseudocentris sp. nov.
Worker. Length about 115 mm.; head and thorax with pale fulvous pubescence, bright orange-fulvous in middle of pleura; clypeus light ferruginous, the upper border infuscated, a median stripe and the lateral comers cream-colored; a cres- centic cream-colored supraclypeal mark, bordered above by ferruginous; cream- colored lateral face-marks broad below, narrowing above, ending above level of middle of front; scape red; third antenna1 joint conspicuously red beneath; abdo- men bright chestnut red, with coarse black hair in apical region, but tuft at ex- Ì
treme apex ferruginous; legs red and black. Extremely close to M. rufiventris
Lep., from which it differs in its larger size and considerably darker abdomen. The legs are marked exactly as in rufiventris, and the face markings essentially agree. Hob.-Manaos, Brazil (Mann & Baker).
I should have con-
sidered this a local race, or perhaps individual variety, of M. rufi-

ventris, were it not that the two specimens are quite alike, while a rufiventris from AbunA exactly agrees with one from F. Smith's collection, now in my possession. There is accordingly some evi- dence of stability in the comparatively slight characters noted. The name of the species is derived from the fact that superficially it is exactly like a red Centris, such as C. tarsata Smith. Ducke asserts that M. mixta Lep. is the same as rufiventris, but Lepele- tier says the hair of the head and thorax in mixta is black. Ducke also makes M. fulva Lep. a synonym of rufiventris, but according to a specimen before me, from F. Smith's collection, it is quite distinct; the legs, as Lepeletier describes, are fulvous, the hind tibiae without black markings, although the anterior and middle tibiae are strongly infuscated. In rufiventris the hind tibiae are red with about the apical half black, and there is long black hair on the posterior margin.
Melipona abunensis sp. nov.
Worker Length 10 mm. or slightly more; head, thorax and legs black, the large apical tarsal joints dark red; abdomen chestnut red, without bands; head broad; clypeus bare, dullish, minutely roughened, with a feebly indicated median dark red stripe; mandibles black, edentate; malar space large; sides of face bare; scape black, red at extreme base; flagellum reddish beneath; vertex with long black hair, occiput with light fulvous hair; mesothorax shining black, more than the posterior half bare, anterior part with long black hair, with shorter pale hair intermixed; scutello mesothoracic suture with black hair in front and pale behind; scutellum prominent, wholly black, apically with a tuft of long black hair, but the hind mar- gin with long pale fulvous hair; sides of metathorax with pale hair; hair of pleura pale anteriorly, but black below wings; anterior femora fringed with whitish hair behind, their tarsi with red hair on inner side; the broad hind tibiae fringed with black hair; tegulse ferruginous; wings orange-ferruginous, with ferruginous nervures; hair of apical part of abdomen mainly ferruginous, but some dark hair at sides of the last three segments; first abdominal segment with a black spot on each side. Hab.-AbunA, Rio Madeira, Brazil (Mann & Baker). The general appearance is like an overgrown M. mandacaia Sm., with the abdomen much brighter red. On more detailed comparison there are many differences, as in the color of the legs and base of abdomen.
~rigonarnanni sp. nov.
Worker. Length 7+9 mm., the wings about 8 mm.; rufotestaceous, the head
black, marked with very pale yellow, and the mesothorax black or piceous, mar-

fined with ydlow; pubescence light Mvow; mandibles- light yellow, black at tip, with a strong tooth at inner comer; m&r space nstirow but distinct; dypeua, accept ft pair of aubobaolete reddish bara, elongate suptaclypedl mark (its å´uppe part reddish), and broad lateral face-&h, all pate yellow, the lateral marks filling space between clypeus and airtenme and eyea, ending squarely a little above level of antennw; front and mesothorn pruino~e with å´fin yellodh-gray hair; scape p&Ie '
yellow-testaceous, black above at apex; flaeellttm dark above and fernginow be- neath, last joint red also al-iove; prothorax yellow; narrow lateral margins of meso- thorax yetlow, and anterior margin broadly aubtestaceoua, except a central portion, which is dark; tegulae mfo-ftilvow, winga very long, mlftuaed with orange, except the broad apical field, which is grayish; neirvures fomu&nous; legs bright femgi- nous, with feireuginoua hair, but the broadly expanded apical part of hind tibise piceous, the hind basttarsi black, and the small joints of hind tarsi dark red; abdomen of the long and narrow type, shining, with scanty red hair. Hub.-Porto Velho, Rio Madeira, Brazil, two, one the type (Mann A Baker). Also one from AbunA, Rio Madeira (Mum & Bale). Related to T. cluvipes {Fabr.), which it resembles a good deal in the markings of the head and thorax, but much larger, with longer wings, the scutellum wholly light, etc. It is one of the species placed in the subgenus Tetragons. Trigona rhodoptera ap. nov
Worher. Length about 7+ mm., the very ample wings a little over 8; head black, with the clypeus, supreclypeal area, and more than lower half of cheeka (except a band along orbits) ferruginous; hair of vertex and front dark fuscous; aides of fa* pale grayish poUhose; cheeks densely covered with a short pale yellowish tomen- turn; eyes ferruginous; mandibles quinquedentate, dark reddish, blBAish apically; matar space quite distinct; scape ferruginous, black above at apex; flngellum clear femughow beneath, black above, except at apex; thorax entirely bright ferrugi- nous red, with hair of the same color; t&<e red; wine very red, orange-hilvous, hems clear red; legs red, with the greatly broadened hind tibite mope or less infuscated, having especially a black patch covering the inner half (on both sib of the tibia) apically; middle and hind tarsi infuscated; long hair on margin of hind tibia; sooty; abdomen short, very shiny, &rk fuscous with the base pale rufotesteeeous.
Bab.-Type from Abun&, Rio Madeira, Brazil (Mann & Baker). Also one from Madeira-Mamore It, R. Co. Camp 41, Rio Madeira, Brazil (Mann & Baker).
Superficially not unlike T. manni, but
entirely different in the markings of head and thorax and charac- ter of the mandibles.
T. pallia Lair., also collected at AbunA, is much smaller, with differently colored wings. T. willianu Friese must be a similar insect, but it has ferruginous hairs on the hind

tibiae, and the margins of the wings broadly smoky: the head also must be different.
Trigona frontalis flavocincta subsp. nov. Worker. Like T. frontalw Friese, but the pale markings of the thorax light yel- low instead of white; all the femora and anterior and middle tibiae and tarsi, clear ferruginous. Length 3 mm.
Hab.-Independencia, Parahyba, Brazil (Mann & Heath). Friese described T. frontalis from Honduras, without citing any precise locality or collector. Professor C. F. Baker kindly sent me four which he collected at Chinandega, Nicaragua. Some of the same lot, he informed me, were determined by Friese. Trigona pellucida sp, nov.
Worker. Like T. amalthea (Oliv.) except that the wings are clear, somewhat milky, with the apex a little dusky, the stigma and nervures bright clear ferrugi- nous; abdomen sepia-brown basally; hind tibia reddish, but dark; small joints of tarsi deep ferruginous. Length 5i mm., anterior wings 5. Mandibles dentate, obscure reddish at apex.
Dorsal surface of abdomen distinctly keeled. Hab.-Porto Velho, RiaMadeira, Brazil, one (Mann & Baker). This seems to be related to T. amalthea as T. fiavipennis Friese is to T. ruficrus. Possibly both represent mutations. Trigona branneri sp. nov.
Worker. Length 6s mm., anterior wing 61; like T. guiance Ckll., but smaller, with the wings only very faintly dusky, with a yellow stain in the base of the mar- ginal cell and along the subcostal and basal nervures; abdomen shining black; short tomenturn of thorax above dark fuscous, hardly noticeable; mandibles dark castaneous, dentate.
The series of eight is quite uniform in appearance. Com- pared with T. mficrus, it is at once known by the pale wings, and the black hind legs; compared with T. amalthea, it is larger, with pale wings, and the scape and flagellum both chestnut red beneath. The wings, although pale, are dusky com- pared with those of T. pellucida. I might think T. branneri to be T. flavipennis Friese, but Friese says the posterior tibiae of his species are more or less fulvous, which is not true of ours. A species which superficially looks just like T. branneri is T. postica (Latr.), but postica has a dull abdomen (except the extreme bases of the segments), with two patches of light pubescence on the fifth segment, and also a finely rugose punctate mesothorax.

The scutellum shows no trace ot a keel. Hub.-Port0 Vdho, Rio Madeira, Brazil (Mann & Bdker).
Of the genus CoelkGa no less than 94 neotropical species have been described, but I cannot identify this with any of them. It appears to be close to C. lapmgdu Smith, from Pard, but the angular apex of the scutellum of our species can hardly be called "a broad spine," while the account of the abdominal banding does not at all agree. In Schrottky's table in his Catamarm paper (1909) C, ardes6en~ runs to edervM-a Schrottly, and agrees well in several

respects, but that species is evidently much more closely punctate, and the lateral spines of the sixth segment are said to be short. In Schrottky's table of Brazilian species it runs to the vicinity of C. agilis Sm., which is smaller, with no red on abdomen, and C. rufopicttz Sm., which is larger, with darkened wings in which are irregular transparent spaces. In Holmberg's table (1903) it runs out at 23, because the fourth ventral segment is perfectly simple, without any process or teeth. In Friese's Argentine table (1908) it runs to a species doubtfully determined by him as C. Szmillima Sm., but I have seen the type of sim?Zlima, and it has a dark stigma (cf. Trails. Am. Ent. Soc., XXXI, 335). Comparison with the various species not included in the tables does not indicate identity in any case. Among the northern species, our insect is to be compared with the Mexican C. otornHa Cresson, to which it must be closely allied, differing however in the abdominal banding,

up orbit; scape not enlarged, black with the basal two-thirds yellow in front; yellow markings of thorax nearly as in male, the two stripes on mesothorax well-developed, but the tubercles are entirely dark, the pleura has no yellow mark, the yellow band on scutellum is broadly notched behind, and the yellow of the metathorax is re- duced to an irregular mark shaped rather like an agaric, at each side of theenclosure; tegulae rufofuscous, with a very small yellowish spot; legs black, anterior pair with a yellow stripe from near middle of femora nearly to end of tibise; middle legs with a yellow patch on apex of femora and base of tibiae, hind legs with a yellow mark at end of femora; anterior and middle tarsi thick, with reddish hair; posterior knee-plate large, long-oval, covered with dark reddish hair; long hair of hind tibiae and basitarsi white on outer side, shining yellowish-white on inner side of tibiae, dark fuscous on inner side of basitarsi; both tibia1 spurs of hind legs large; apical plate of abdomen with fine concentric striae; apical hair chocolate, but ventral segments fringed with white hair; venter all black. Hob.-Independencia, Parahyba, Brazil, 2 males, 1 female (Mann & Heath). This is the third known species of Cmonomada. It is close to C. bruneri Ashm., but easily separated by the presence of large yellow stripes on the mesothorax in both sexes, and other details of the markings. From Ccenonomada pluricincta (Tetra- pedia pluricincta Vachal), from Goyaz, it is separated by the yellow markings of the thorax, the color of the legs, etc. Vachal suggests that ~picharii unicalcarata Ducke may also prove to belong to Ccenonomada. Vachal protests against the use of Ashmead's generic name Ccenonomada, on the ground that the description was insufficient, and the insect was placed in the wrong family. I believe, however, that Ccenonomada must be considered to have been established according to the rules, although one could wish it were possible to adopt instead Holmberg's Chacoana, which was well-defined and well understood by its author. Psaenythia canina sp. nov.
Male. Length about 8 mm.; black with bright lemon-yellow markings, no red on head, thorax or abdomen; head extremely broad, eyes diverging below; clypeus with long pointed lateral lobes; clypeus (except two dots and lower margin), a large quadrate area (twice as broad as long) on labrum, broad lateral face-marks shaped like the mainsail of a schooner, large dog-ear marks, and an elongated mark on upper part of cheeks, all yellow; supraclypeal area and scape entirely black; flagellum ferruginous beneath, darkened basally; mandibles long and slender, the basal half yellowish, the apical red; front rugose, cheeks shining; mesothorax shining, very finely and closely punctured; upper border of prothorax, tubercles and a spot behind them, a pair of oblique marks extending over axillae and side of scutellum, a stripe on postscutellum, and two marks near the middle of the base of meta-

thorax, all yellow; scutellum shining, the punctures larger and much less dense than on mesothorax; legs piceous, the small joints of tarsi light reddish-brown; a small spot on all the knees, stripe on anterior tibiae, and base of middle tibise above, yellow; hind tibiae with silvery-white hair; tegulae light fulvotestaceous; wings dusky; abdomen with bright yellow bands on first six segments, widely interrupted on second and third, with a linear interruption on the others; apical plate very large, obtusely emarginate, bulging laterally; genitalia ferruginous. Third s. m. unusually long.
Hab.-Independencia, Parahyba, Brazil (Mann & Heath). In the tables by Schrottky and Friese this runs to P. burmeisteri Gerst, which however is much larger, and otherwise different. From all the races of P. picta Gerst., it is known not only by the details of the markings, but also by the very much more finely punctured mesothorax. In the shape of the head, and in the face-markings, there is much resemblance to P. philanthoides Gerst., but the head is broader, and the colors are quite different. The name canina may be taken to refer to the bulldog-like head or to the well-developed dog-ear marks.
Megachile lenticula Vachal.
Female.
Length 10+13 mm.; black, including the legs, except that the hind coxae, trochanters and basal half of femora are ferruginous above; tegulae clear bright ferruginous, the anterior margin somewhat expanded; wings strongly dusky; hair of vertex, mesothorax and scutellum coarse and black, of sides of thorax fulvous above, whitish below, with a little black hair below the wings; metathorax with pale fulvous hair, and pale hair in scutello-mesothoracic suture; face and front with mixed cream-color and black hair; clypeus and supraclypical area bare, shining, with scattered punctures; middle of clypeus flattened, sides subrugose, lower margin thickened and broadly concave; mandibles quadridentate; abdomen with narrow entire pale fulvous bands on the second and following segments, and pale fulvous hair at extreme sides of first; basal part of abdomen red beneath; ventral scopa creamy-white, largely black at sides and apex. Hob.-Porto Velho, Rio Madeira, Brazil (Mann & Baker). Madeira-Mamore R. R. Co. Camp 43 (Mann & Baker). Male also at Porto Velho.
I had regarded the female as a new species, but it is evidently the undescribed sex of M. lenticula Vachal. The following table contrasts the female with some species which it resembles.

56 Psyche [April
HabTPorto Velho, Rio Madeira, Brazil (Mann & Baker). This little species resembles the Mexican M. bidentis Ckll., but differs in the color of the wings, dark fuscous nervures, and some- what larger head. They are however closely related. The color of the nervures and tegulse will also separate M. microsoma from the South American M. pilosa Sm.
Megachile permunda sp. nov.
Male.
Length about 9 mm.; black, the femora and tibiae a rather lively chest- nut red, all the tarsi light yellow; a short compact species, superficially like the Australian M. sequior Ckll.; eyes light green, the lower part tinged with red; man- dibles and antennae black, the flagellum very faintly reddish below; face densely covered with shining golden hair; lower part of cheeks, and under side of thorax, with pure white hair; the broad vertex, and thorax above, with long erect dark fuscous hairs, but mesothorax margined all round, and scutellum in front and behind, with dense fulvous tomentum, the edge of the fulvous area in front of mesothorax trilobed or tridentate posteriorly; abdomen with entire pale fulvous apical hair- bands, but band on fourth segment broadly interrupted, while fifth has no apical band, but its basal third or more is densely covered with appressed fulvous hair; sixth segment densely covered with creamy-white hair, except the projecting mar- gin, which is broadly emarginate, but otherwise simple; ventral segments with white hair-bands; apical antenna1 joint slightly broadened; mesothorax and scutellum dull, densely granular; tegulse dull ferruginous; wings dusky; anterior coxse with strong black spines; anterior tarsi hardly broadened, but with a long white fringe behind, on the inner side of the fringe is some black hair; middle tarsi posteriorly with extremely long white hair; hind tarsi with long white hairs in front; spurs yellowish-white.
Hob.-Natal, Brazil, two males (W. M. Mann). Except for
the almost simple anterior tarsi, this much resembles the Mexican M. veraecrucis Ckll.
Exomalopsis paraguayensis manni subsp. nov. Female.
Length about 8 mm. ; black, the mesothorax, scutellum and abdomen shining; agrees with the description of E. paraguayensis Schrottky, except as follows: mesothorax shining, not very densely punctured, the anterior third with scanty pale hair, the posterior part with very scanty black hair, easily overlooked; scopa of hind legs creamy-white, the basitarsi densely black-haired behind; wings dusky at apex; stigma large, amber-color, nervures more dusky; tegulse rufo- piceous. The head is broader than long, and the abdomen is elongate, not sub- globose as in many Exomalopsis.
The base of the metathorax is roughened. The
mandibles are black, with a bright red spot about the middle. The b. n. goes
basad of t. m., and second s. m. is very small.

Hob.-Natal, Brazil {W. M. Mann), Probably a distinct species, but agreeing so nearly with the description of D. para- guay-s that I leave it for the present as a subspecies. Tapinotaapia heathi a. sp.
Afofe. Length about 88 man., anterior wing nearly 8; shining black, the supra- dypeal region, front and abdomen very brilliant; pubescence mainly black, but dense and shining creamy-white on clypcus and sides of face, long silvery haira project below mandibles, the anterior half of pleura has long plumose white hair, anterior legs with white hair on outer side, hair on inner side of hind tibiee dull white, and on inner side of their tarsi pale fei~uginous; fourth abdominal segment with a tuft of white hair on each side, fifth and sixth with white hair at sides, and dorsally in the subapical region with glittering, pale, partly metallic hairs; under ride of abdomen with black hair-hands; hair of thorax above, and the very abundant hair of Middle legs, all black; malar space obsolete; supraclypeal area smooth and impuncttete; anteattse long and slender, scape black, flagellum ferruginous, pale beneath, the first joint largely dark, ih last three joints on wiw side, awi a square patch on apkd part of the OM before, shining wcns-TehIfe; mesothorax itucmcopically sculptured; anterior wings dark fuUginous, the apical field very large, nervures fag- cons, stigma, rather large, reddish; b. n. meeting t. m.; marginal cell obtusely pointed at apex, away from costa; first and second aubmitrghla about equal, third larger; second quadrate, narrowed about a third above, receiving first r. a. almost at its apex; third s. m. broader above than second, meiviag second r. n. a little beyond beginning of its last third; lower wings hyaline, darkened on costa and broadly so at apex, anal lobe very well developed; hind basitarsus nearly as long as tibia, produced at end into a thumb-like lobe which is largely red; first three abdominal segmenti without apical hair, except at sides; fourth with a short purplish-blaclr fringe, fifth and sixth with heavy black fringes; apical plate broadly truncate. The
elongate two ha1 joints of labial palpi are subequal, Hub.-Independencia, Parahyba, Brazil (Mann <!(å Heath). This may perhaps have been described as a Tetrapedia from the female, but if so, there is no way to ascertain the fact. It looks
like Tetrupedia diversipes Hug, except for the smaller size and the color of the hair on the hind legs.
The venation is however entirely
different from that of T. diversipes, and also very different from Emmalopsis, to which genus I next thought to refer it. The
reference to Tapino/mpis is unsatisfactory, because the second submarginal cell is not at all as in that genus, but it is possible that the definition of Tapinofaspis may be altered to include such forms as the present, Tapinoitospis is considered by Brethes a synonym of Tetrawiu, while a species was described by Friese as an Exo- m+&. It is probably a valid genus, or at any rate, the species

now described is generically distinct from both Tetrapedia and Exomalo psis.
Diadasia Patton.
The three bees described below are referred to Diadasia, which is probably distinguishable from Ancyloscelis. I have not been able to examine the type of Ancyloscelis (A. ursinus Hal.), but from what I can learn, I believe it is a Dipedia or Leptergatis. Holmberg's Leptometria and Teleutemnesta have been referred to Ancyloscelis, but they have an apparently valid character in the hind wings, pointed out by Holmberg; the separation of the discoidal and cubital nervures takes place about half way between the trans- verso medial and the transversocubital, instead of very much nearer the transversomedial as in Diadasia, etc. In this character the bees now described agree with Diadasia, and are readily separated from Leptometria and Teleutemnesta. The North American Dasiapis, which in some ways closely resembles Leptometria, has the Diadasia venation of the hind wings. Diadasia parahybensis sp. nov.
Male. Length about 6+ mm., the abdomen short and subglobose; black, wholly without light face-markings, the long tarsi, and apical spot on tibiae, fer- ruginous; eyes pale ochreous; facial quadrangle very much longer than broad; hair of head and thorax very pale ochreous, almost white, quite white below; on vertex the short hair is stained with brownish; flagellum ferruginous beneath; mesothorax shining, with rather dense strong punctures; tegulse dark reddish; wings strongly dusky; b. n. meeting t. m.; middle and hind femora incrassate, but not excessively so; hind spur of hind tibia considerately longer than the other; hind basitarsus gently curved; abdomen covered with a short felt-like reddish tomentum, the hind margins of the segments broadly pallid but also hairy. Hub.-Independencia, Parahyba, Brazil (Mann & Heath). In Friese's table of Ancyloscelis (Flora og Fauna, 1908, p. 51) this runs to 4, and runs out on account of its size, but really comes nearest to A. riparia Ducke, with which it agrees in the keeled sixth ventral segment of abdomen; it differs, however, by the dusky wings and the color of the hair of the head. In my table of North American species (Amer. Nat., XXXIX, p. 742) it runs to Dia- dasia diminuta (Cr.), from which it differs at once in the character of the abdominal hair, which in diminuta is long and loose.



================================================================================

CoclcereZZ-New Bees from Brazil
Diadasia murihirta sp. nov.
Male.
Length about 11 mm.; black, the head and thorax with rather dense hair, which is warm ochreous above (fuscous on scutellum, and slightly so on disc of mesothorax) and white below, the transition from one color to the other quite gradual; small joints of tarsi ferruginous; antennae short for a male, the flagellum obscurely reddish beneath; clypeus densely covered with light hair; mesothorax with small but strong and rather close punctures; hind femora incrassate but not at all subglobose; spurs piceous (in Dm parahybensis they are cream-color); hind basitarsus curved, red at apex but not prolonged; tegulae fuscoferruginous, pallid at sides; wings moderately dusky (not reddish as they are in D. sumichrasti vul- pihirta); abdomen with pale ochreous hair on first segment, the other segments with very short and thin black hair (obscure brown on basal half and sides of second), and broad dense apical ochreous hair-bands; sixth ventral with a large median hair-tuft.
Hub.-Independencia, Parahyba, Brazil, 2 males (Mann & Heath). In Friese's table runs to facialis Friese, differing in the total lack of light face-markings. In the North American table it runs to the Mexican D. sumichrasti (Cr.), but the hair is less brightly colored, while the second s. m., is broader above than in sumichrasti, and receives the first r. n. nearer the apex. Diadasia sumichrasti vulpihirta subsp. nov. Female. Exactly like D. sumichrasti (one of Cresson's cotypes compared) except that it is somewhat larger, the scape is largely red, and the flagellum is partly red beneath, the color especially bright on the second joint and apex of the first. There is a strong contrast between the bright fox-red hair of the mesothorax and region about the tubercles, and the grayish-white of pleura. The abdominal bands are broad and bright ochreous. The mouth-parts are as follows: maxillary palpi 6-jointed, joints measuring in p. (1.) 224 (2.) 416 (3.) 464 (4.) 272 (5.) 176 (6.) 176; apex of second joint, and all of third, with a dense brush of hair on one side; last joint very slender; blade of maxilla about 2400 P- long, about 160 broad near middle, and about 352 near base; maxillary comb very well developed, with about 23 sharp teeth; paraglossse linear, reaching to a little beyond middle of first joint of labial palpus; labial palpi with first joint about 1170 JJ. long and 192 broad, second 1010 long; third (arising laterally 160 ;J. from end of second) 176 long; fourth 160. Labrum about 1360 p. broad and 800 long, apex very obtusely angled, the apical margin with strongly fimbriate hairs. Hab.-Baixa Verde, Rio Grande do Norte, Brazil (Mann). Six females.
