FLIES OF GENUS CONOPS — CAMRAS 171 



C. aurafus was used by Krober for connectens, and gracilis was used 

 for this spppies. Recognition of connecfevs, and the distinction of 

 townsendi (= auratus) from rufus should clear up the confusion of names. 



Range: Texas, New Mexico, Arizona, California.

This species belongs to a well define(] group characterized by a very 

 distinct uninterrupted postvertical pollinose stripe connecting the 

 postorbitals. The group includes townsendi, connectens, and parsonsi, 

 all of which replace each othei- in range. Some of the other species of 

 the subgenus, especially hulhirostri-^ and costaricensis, nicy have a very 

 distinct postvertical stripe, but i( is usually interrupted in the center. 



Range: New York to Florida, \vest to Colorado and Oklahoma.
