subniarginal spots and a paler central belt across the under 

 surface of the secondaries than exist in P. locusta from 

 Bogota ; the female also, from which the figure is taken, and 

 that in the Hewitson collection both have the white area on 

 the primaries somewhat yellower than in that sex of P. locust'x 

 or than in my type. I am afraid that none of these slight 

 differences will prove to be even locally constant, but in the 

 absence of positive proof I temporarily retain the two forms 

 as possibly separate.

Southeni States of N. America, the West Indies, Central 

 America, and a great part of the Southern continent. 



With so wide a range it is naturally extremely variable, a 

 perfect series of gradations existing between typical P. phileta 

 and the feebly bordered P. automate ; these variations may 

 be somewhat arbitrarily divided into seven grades, none of 

 them apparently being confined to any particular region. 



The species has hitherto stood in collections as P. monuste 

 of Linnteus, with which some of the older authors were the 

 first to confound it ; but the description in the ' Museum 

 LudovicEe Ulrica ' cannot refer to this butterfly, inasmuch as, 

 in the first place, no mention is made of the dentated character 

 of the inner edge of the outer border of primaries, but, on the 

 contrary, that of the secondaries is specially described as 

 " denticulato-fuscus " ; in the second place, no mention is 

 made of the elongate subapical white spots on the primaries ; 

 and, lastly, the wings below are said to be concolorous, ex-
