T. D. A. COCKERELL 27 



The Brunei" collection of Argentine bees was divided, a set 

 going to the U. S. National Museum, and one remaining at the 

 University of Nebraska. It is the National Museum set which 

 is here described, and I have added a certain number of other 

 neotropical forms, also in the National Museum, the types of all 

 the new species being in the collection of that institution. 



Dasiapis tropicalis new species 



Female. Length, 10 mm., anterior wing, 7.2 mm.; 0137)6118 black; man- 

 dibles largely creamy white; flagellum bright ferruginous beneath; mesothorax 

 and scutellum entirely dull; tegulae testaceous; wings dusky hyaline; ab- 

 domen covered with appressed pale ochraceous hair, margin of fifth segment 

 and apex with pale yellowish-ferruginous hair; scopa of hind legs very pale 

 ochreous; hind basitarsi with hair on inner side ferruginous. 



Pueblo Viejo, Vera Cruz, Mexico, Dec. 8, 1909 (F. C. Bishopp). 

 Differs from D. olivacea Cresson by being larger, and having 

 pale red hair (instead of fuscous) at apex of abdomen. "S'ery 

 close to D. ochracea Cockerell, but with shorter, dusky wings, 

 redder hair on tarsi; and abdomen not cjuite so densely' hairy. 

 The third and fourth joints of maxillary palpi are fringed with 

 long hair. It is possibly a subspecies of D. ochracea, but inter- 

 mediates are not at present known. 



Xenoglossa rhodophila new species 



Female. Length, 14 mm., anterior wing, 10.3 mm.; robust, black; eyes 

 dark bro\vn; facial quadrangle broader than long; mandibles simple, curved, 

 reddish at tip; clypeus densely rugosopunctate, elevated in middle; antennae 

 dark, joints six to eleven with suffused red spots or areas on outer side; third 

 antennal joint as long as next two combined; ocelli in a line; hair of head 

 white (very long on cheeks) except on vertex and front where it is thin and dark 

 grey; mesothorax shining, well punctured; scutellum with extremely dense small 

 punctures; hair of sides of thorax and metathorax white; dorsum of thorax 

 with a broad band of black hair across mesothorax, bounded in front and be- 

 hind by dull white; middleof scutellum with dark hair; tegulae piceous; wings 

 dusky subhyaline; first recurrent nervure joining second submarginal cell 

 near end; legs with pale hair, fuscous on inner side of tarsi; abdomen with 

 hind margins of segments testaceous (narrowly on first); first segment hairy 

 at base, Init otherwise bare; second bare, with minute punctures; remaining 

 segments covered with pale fulvous hair, the fourth with a beautiful golden 

 fringe. The type has collected a quant it y of deep red pollen. 



Mexico (Baker coll. 2386). Allied to A', fulviventris {Tetra- 

 lonia fulviventris Smith), but distinguished by the bare second 

 abdominal segment, white hair on head and thorax, etc. The 

 blade of maxilla is much larger than in fulviventris. The venation 

 is not that of typical Xenoglossa.
