 separated punctures, and a smooth median line; malar space 

 short, but distinct; process of labrum broadly truncate, with

 dark, not hairy, rather broad, reaching a little below level of 

 antennae ; cheeks very broad, with a little tubercle on hind

 long as next three together ; mesothorax and scutellum dull

 granular; tegulse piceous, with much red hair. Wings 

 dusky translucent, nervures and stigma reddish brown;

Hob. Jimtown, Colorado, at flowers of Therinopsis, June 7 

 [Cocherell). 



The specimen is stylopized, and perhaps somewhat altered, 

 but it appears to be a quite distinct species. It is very like 

 A. milwaukeensis, Graenicher, but differs by the light hair 

 on the face and pleura, the broad cheeks, &.c. There is 

 evident close affinity with A. ribesina, CUU., but the third 

 s.m. is very much broader above, the small joints of tarsi 

 are dark, the hair on the abdomen is differently coloured, 

 and the cheeks are broader and flatter. It is perhaps 

 possible that the insect is an extreme variety of A. ribesina. 

 ill the key in Proc. U.S. Nat. Mus. vol. xlviii. pp. 1-58, 

 it runs nearest to A. topazana, CklL, which is smaller and 

 otherwise distinct.
