HygTOC8leuthu3 latipas Lnrw. 



The figure in I.oew's monograph ( \. .\. Dij^lera II. pi. iii, 1) in- 

 correctly represents the middle tarsi of the male as being flattened, 

 instead of compressed; the first joint of the antenna, also, is more 

 hairy than shown, and the face of the female does not reach the in- 

 ferior corner of the eye. In the description (p. 18), line 10, ''tibiae" 

 should read "femora." The first joint of the antenna is not at all 

 blackened in most of my specimens; the thickening of the costa is pe- 

 culiar to the males. 



Numerous specimens. Brookings, S. I), (common in September); 

 ^^'yoming: Connecticut. 



Hyg-roceleuthus crenatus ( ). .s. 



Numerous specimens from California, and two from Washington. 

 Osten Sacken's material was not sufficient to enable him to discover 

 one very interesting fact concerning the tegular cilia of this species 

 and afflictiis. In the male they are light yellow, fine and delicate; in 

 the female they are of ordinary size and black, except a few of the 

 smaller ones above and below, which are yellow. 



A single male from Washington differs from the rest in having the 

 antennae slightly longer, blacker, and more hairy; and the arista 

 shorter and more densely hairy (see figure). These differences in a 

 single specimen do not justify the erection of a new species. 



Hygrcceleuthus afflictus O. S. 



One male and two females, California (Coquillett). The male is 

 easily distinguished bv the bunch of vellow hair on each side of the
