This streak has parallel and straight edges, and is limited on both sides by a narrow edging of pure white scales. Beyond the end of the cell is a large ill-defined ashy brown shade, limited basally by a line of unmottled white and reaching nearly to the terminal edge: beyond it is a short oblique whitish fascia across the tip of the wing. Extreme apex ashy brown. Cilia white with dark fuscous tips. Hind wings light whitish fuscous on the upper side, faintly showing the ornamentation of the under side, which is whitish with dark fuscous transverse lines. Abdomen and legs ochreous white, slightly dusted with light fuscous."
