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. 
(i) Plestia dorus, Edwards, Plate 
XLV, Fig. ii, $ (The Short-tailed Ari¬ 
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.
