AN AX, Leach. 



This genus differs from all other members of the 

 Alschninss in the male having the anal angles of the 

 hind wings rounded. The species are very large and 

 their flight is strong. A. Junius is an exceedingly 

 abundant form in all parts of the state. A. longipes 

 has never been taken in Ohio, but Mr. Charles Dury is 

 confident he identified the species on the wing at Cin- 

 cinnati in May 1898. 



The following table will serve to separate these two 

 species : 



1. Front above with a fuscous spot surrounded by green and the 

 whole by blue .Junius. 



2. No markings on front above longipes.
