NO. 1G74. DESCRIPTIONS OF SOME BEES—COCKERELL. 419 



dense white loineiitiiiii; ycutelluiii with hiteral lobes, and postscu- 

 telhmi produced, exactly as in N. mutellaris Saiissure, from Madagas- 

 car; antemite black, the Hagellum stout, greyish-pruinose ; niesotliorax 

 with dense but rather shallow punctures ; scutelluin very densely punc- 

 tured; teguhc large; anterior wings fuscous-black, with violaceous 

 tints; posterior wings hyaline; legs black, the coarse scopa of hind 

 legs black; anterior and middle tibiae each with a large patch of white 

 hair on outer side, occupying all but apical part of anterior, but little 

 more than basal half of middle ones ; some white hair also behind the 

 hind knees. 



Habitat. — Jombene Eange, East Africa (Chanler-Hohnel Expedi- 

 tion). The specific name should apparently have been chanhri, not 

 chandleri The above description disagrees in some important par- 

 ticulars with Ashmead's brief account, and the type specimen bears a 

 specific name dedicating the insect to Doctor Abbott. It is, however, 

 the true (and unique) tyj^e, as Doctor Ashmead showed it to me when 

 I was in Washington some years ago, remarking that he had labeled 

 it under the imjDression that it was caught by Doctor Abbott, and 

 would have to change the name. The name C rocisasjndia may very 

 well be used in a subgeneric sense, for the species of the group of 

 Nomia scutellaris, namely : 



(1) N. scutellaris Saussure. Madagascar. With entire white 

 bands ; wangs not very dark. 



(2) N. maculata (Friese). Grotfontein, Southwest Africa; 

 Langenburg, Lake Nyassa. Abdominal segments one to four with 

 bluish-white spots on each side ; scopa white. 



(3) N". nigripes (Friese). Ondonga, Southwest Africa; Old 

 Calabar, West Africa; Chinchoxa, Africa; Togo, Africa. Much like 

 maculata^ but scopa black, etc. 



(4) N. amahilis Cockerell. Benguella. Similar in most respects 

 to chandleri^ but postscutellum without wdiite tomentum, and its lobes 

 nuich more pointed; while the abdominal markings are of quite a 

 ditferent tint, a clear blue with purplish shading, whereas in chaiid- 

 leri^ they are of a deeper and greenish-blue by compariso^i. 



(5) N. chandleri [cA/m^cW] (Ashmead). 



NOMIA (HOPLONOMIA) QUADRIFASCIATA (/ .imcad). 

 Hoplonomia quadrifasciata Ashmead, Journ. N, Y -^iit. Soc, XII, p. 4. 



I have examined the type; the abdomin?" oancls are green, tinged 

 w4th orange-vermilion. 



HALICTUS PHILIPPT . i>ISIS Ashmead. 

 Halictus 'i)MUpinnensis Asiimkad oc. U. S. Nat. Mns., XXVIII, p. 128. 



A species with the general .pect of H. pectoralis,' the hind spur of 

 hind tibia? long pectinate , third submarginal cell of the short type; 

 hair of abdomen at lateral bases of segments one and two, and across 

 on three and four.
