femur. Tarsus about two thirds the length of the tibia ; first joint elongate, cylindric, 

 slightly curved, one half longer than the rest combined ; second, third, and fourth transverse, 

 progressively shorter ; all these armed at the apex on each side with a stout spine ; fifth joint 

 small, not transverse, unarmed. 

 Middle and Posterior Legs with the femora and tibiaa of about ecmal length, the latter very spiny ; 

 the spurs distinct, moderately long. Tarsi nearly as long as the tibiae, very spiny both above 

 and below ; the lateral spines longest, those on the soles arranged in two or three rows ; all the 

 joints nearly of equal thickness, and cylindrical. Claws long, but little curved, lobed at the 

 base, grooved below. Paronychia and pulvilli rudimentary, or entirely wanting. 

 Abdomen not so long as the inner margin of the posterior wings. 



Larva cylindric, armed with long, ciliated spines. 

 Pupa angular, tuberculated. 



Agraulis resembles the preceding genus in the simple structure of its claws ; but may be at once distinguished by 

 its more elongate wings, which are fulvous, banded or spotted with black on both surfaces, and splashed with silver 

 below. In many respects, especially in the form of the wings, it approaches Cohenis more closely than the preceding- 

 genus. It is closely allied to Argynnis and Cirrochroa. 



The Larva of Agraulis Vanillic differs but little in form from that of the European species of Argynnis, being 

 cylindrical and set with numerous ciliated spines. It, is brown, with darker longitudinal stripes. It feeds on various 

 species of passion-flower, but not, I believe, on the plant after which it has been named. In East Florida I have found 

 the larva in profusion in the spring on Passiflora incarnata. It changes to an angular or rather tuberculated pupa 

 with a large prominence on the back. After seven or eight days the butterfly makes its appearance. 



The flight of the Perfect Insect is graceful, and at times rapid ; it is fond of alighting on the flowers of the 

 Passiflora, and is then by no means difficult to capture. In many respects its habits resemble those of our own Argynnis 

 Paphia. Its ordinary time for appearance is May and June; but I saw a very perfect specimen on the 21st of 

 December, 1837, at the little village of Mandarin on the St. John's River, East Florida. 



This species has a wide Geographical Range, extending from Georgia to the South of Brazil. The two other species 

 of the genus appear to have a more limited one, especially Agraulis Moneta.
