HESPERIA. 
23 
I have adopted the last two genera of the Felders, not be¬ 
cause there are any structural differences sufficient to di¬ 
vide them from Eudamus, but because the eye, which is in 
many cases the best guide to the formation of genera, at 
once detects a distinctive character. 
Genus HESPERIA. 
1. Hesperia Eudega.

Upperside. Male. —Rufous-brown. Anterior wing 
with six transparent spots: three a little beyond the middle 
forming a triangle, and three before the apex: a band of grey

This species has a great resemblance to Ismene Benjaminii.
