male from El Yunque, c. 3000 ft., Puerto Rico, May, 1931

the genitalia, fails to show any differences of a specific 
nature.

This is known only from the male type, which was col-

americanus , although the amount of anastomosis is not 
indicated. According to his drawing, the hind wing is

Probably more closely allied to Dilar than to Nallachius. 
Female: Body structure essentially as in Dilar as far as
