Genus Plestia 



upon leguminous plants, especially upon the Wistaria and various 

 species of Clitoria (Butterfly-pea). It makes a rude nest for 

 itself by drawing two of the leaves together with strands of silk. 

 The species is tropical and is found all over the tropics and 

 subtropical regions of the New World, but ranges northward 

 along the Atlantic sea-coast, being occasionally found as far north 

 as New York City, where it has been taken in Central Park. 



Genus PLESTIA, Mabille 



Butterfly. The club of the antennae is flattened, sickle-shaped, 

 terminating in a fine point. The male has a costal fold upon the 

 fore wing. The lower radial is nearer to the upper radial than 



to the third median nervule. The hind 

 wing is produced into a short tail. The 

 fifth vein is wanting. 



Early Stages. Unknown. 

 This genus is peculiar to Mexico and 

 Central America. But one species is found 

 within our limits, and is confined to Ari- 

 zona.

Antenna, magnified 2 diam- XLV, Fig. II, 3 (The Short-tailed Ad- 

 eters. Neuration. c , \ 



zona Skipper). 



Butterfly. The upper side is accurately depicted in the plate. 

 On the under side the wings are hoary. The spots of the upper 

 side reappear, the lower spots of the primaries being partially 

 lost in the broad honey-yellow tint which covers the inner mar- 

 gin of that wing. The secondaries are crossed by obscure dark- 

 brown basal, median, and postmedian bands, portions of which 

 are annular, or composed of ring-like spots. The anal angle is 

 clouded with dark brown. Expanse, 1.50-1.60 inch. 



Early Stages. Unknown. 



The species has been taken in considerable numbers in Ari- 

 zona, and ranges thence southward into Mexico. 



Genus EPARGYREUS, Hubner 



Butterfly. The antennae have the club stout, gradually thick- 

 ened, tapering to a fine point, and abruptly bent into a hook.
