120 PACKARD, HUMBLE BEES, ETC. 



with sparse greyish-yellow hairs, being very thin between 

 the wings, and on the middle of the fourth joint of. the 

 abdomen ; beneath black. The abdomen is at the ex- 

 tremity a little broader and more incurved than in the 

 preceding species. My specimen is very pale greyish- 

 yellow, Mr. Cresson however describes it as " pale lemon 

 or greyish-yellow above and on the sides," and it is most 

 probable that the specimen before me is hardly mature. 

 Legs, outer half of tibiee, and tarsi fuscous. Length, .55 ; 

 breadth, .28 inch. (Mus. Comp. Zool., Mr. Norton.) 



Apathus elatus Cresson. 



Male. Yery closely resembling B.fervidus Fabr. The 

 head is black, rest of the body, except a black band 

 between the wings, and the black tip of the abdomen 

 deep lemon-yellow. Wings much darker than in the pre- 

 ceding species. Legs black, sometimes dark fuscous ; 

 femora clothed with yellowish hairs beneath. The extreme 

 tip of the abdomen has a few fulvous, or yellow hairs. 

 Distinguished from B. ferviclus chiefly by the black front. 

 Length, .55 — .85 ; breadth, .25 — .35 inch. 



Nephopteeyx Hiibner. 

 Nephopteryx Edmandsii nov. sp. 



Cinereous, with a decided purplish hue. Head, an- 

 tennae, thorax and abdomen rather pale cinereous, con- 

 colorous, without any dark scales ; palpi much darker at 

 the tips and on the outer side; within paler. Fore wings 

 with two transverse parallel lines ; the inner one a little 

 outside of the basal third of the wing ; blackish, diffuse, 

 angulated just before the costa, straight below ; a slight 

 blackish discal dot ; the outer sub-marginal line is situated 

 on the outer fourth of the wing ; it is dark within, the outer 

 half pale, straight, angulated acutely opposite the discal 

 dot ; not angulated in the costa ; just within this line and 

 in front of the discal clot there is a pale patch, free from 

 the dusky scales. An obscure marginal row of dots, the 

 apical one much larger than the others. Fringe pale cine- 

 reous. Secondaries, abdomen and legs uniform pale shiny
