I have compared this species carefully with the original 
description of Westwood and Rambur. I feel confident now 
that they pertain to the same species, and this one appears to

to the other. The males are considerably smaller and slenderer 
than the females, and as a usual thing the wings of that sex 
are paler.

This species is of the form and appearance of rufescens. It 
is smaller than specimens of that species usually are, and the 
wing markings are reduced. The type is in the Banks Collection.
