CHARLES W. HOOKER. 99 



hind coxae and trochanters black, yellow at their junction, the base of 

 the hind femora and apices of the tibia and tarsi black. In most of 

 the specimens the hind femora and tibiae incline to fuscous or black, 

 perhaps owing to discoloration. 



I have not seen a specimen of this species, and can only 

 give Cameron's description. 



Types. — 9 and cf . Location unknown.* 

 Distribution. — The type was taken at Ciudad in Durango, 

 Mexico.
