 MALE, TO SHOW Front wlth short black pile; first antennal joint 

 ^ ° of medium size, a little swollen, cinereous, with short 



black pile above, pale below; third joint rather large, kidney shaped, 

 its vertical diameter a little greater than that of the first joint; sides 

 of face with rather abundant whitish pile; palpi yellowish to red, 

 generally dark along lower edge, with pale hairs; proboscis short, 

 labella fleshy. Pile of mesonotum largely black, of remainder of body 

 mostly yellow, wings subhyaline, veins yellowish near base. 

 Length of male, 5^ mm. ; of female, 4f-5f mm. 

 Forty-five specimens, both sexes; collected about Pullman, Wash- 

 ington (type locaUty), and Moscow, Idaho, by Professor Melander and 

 myself; one is from Juliaetta, Idaho. 



The female appears to differ uniformly from pacTiyceras in having 

 pale halteres ; I find very little to separate the males.
