The Genus Pyrrhocalles Mabille with the 



Description of a New Form Lepidoptera, 



Hesperidae. J 



By Henry Skinner, Philadelphia. 



The genus Pyrrhocalles was described in the Genera In- 

 sectorum (Hesperidae) in 1904. The only species mentioned 

 is Pamphila antiqua Herrich-Schaffer and the localities given 

 are the islands of Cuba and Haiti in the West Indies. We 

 have in the collection of The Academy of Natural Sciences of 

 Philadelphia three forms: one from Haiti and San Domingo, 

 one from Cuba, and one from Jamaica. The insect from 

 Jamaica was described by J\lr. William Schaus as Phemiades 

 jamaicensis* 



This is a perfectly good species and shows no tendency to 

 gradation. We have four specimens of a Pyrrhocalles from 

 eastern Cuba which I have always taken to be antiqua Herr.-
