Genus APHARETRA Grote 



This is a small genus, the species of which have been 

 separated from Apatela, in which they have been formerly 

 placed. We give figures of both species known to occur within 

 our territory. They have been drawn from the types, and will 

 suffice for the identification of the perfect insects. Nothing is as
