THECLA. 17 



Though evidently allied to the preceding species, the males having the pouch on the 

 secondaries beneath near the median nervure, T. nepia is undoubtedly distinct ; the 

 silvery hue of the wings above and of the inner portion of the primaries beneath alone 

 serve to separate it. Three male specimens are all that we have yet been able to 

 obtain. Dr. Staudinger has one, also a male, in his collection from Chiriqui. Our 

 figure represents a male from the Polochic valley.

A close ally of T. lisus (Cr.), differing in the underside of the wings being brown, and 

 in the innermost of the transverse bands of the primaries being more oblique and further 

 from the apex of the wing. Of this species but very few specimens have come under 

 our notice ; these are from widely different localities. The figures represent a male from 

 Central Guatemala and a female from Costa Eica.
