ceropalinae: tribe ceropalini 



245 



This subspecies is the most widespread one in North America. It 

 differs from the subspecies caenosa in having a yellow apical band 

 on the third tergite, from rhodomerus in having the hind femur blackish 

 or brown rather than rufous, and from stretchii in the less extensive 

 yellow markings, having less than the apical third of the hind femur 

 marked with yellow, usually a median black stripe on the face and 

 clypeus of the female, and narrower yellow bands on the abdomen. 

 Intergrades and mixed populations with the other subspecies are 

 common.
