fuscus, tho anal angular area greyish-white and containing two black 
marginal spots, separated by the first median nervule, a smaller spot at

with dark medial lines. A large cupshaped depression on the disc, 
below the inner margin, shining and very conspicuous in certain lights. 
Underside. Forewing pale reddish ochraceous with the area beneath the 
median nervure and first median nervule greyish. A small grey cavity in 
the middle of the inner margin of the forewing bearing a tuft of orange
