In a doubtful female the whole dorsum is of the same color as the head, the abdomen 
as before stated. The broader fore- wings are lighter at the front margin, plentifully 
sprinkled with uniform gray without the usual ocherous color in the middle, and the 
general ocherous tone of the whole. At the fold lies a black dot with a whitish border. 
Obliquely behind and over this dot there is no double spot, but a separate stronger 
deep-black ringlike dot, bright and strikingly inclosed. The cross-vein dot is smaller, 
but also black and similarly ringed with light color. Since the hind fringes are almost 
entirely broken off, I can not say further about the markings. The hind wings are 
sensibly broader than the fore-wings, and less finely pointed.
