Forewing with a somewhat broad straight discal deep ferruginous band from the costa almost reaching the sub-median nervure, its outer edge very even, its inner edge a little irregular. Hindwing with a similar discal band, but posteriorly curved up to the abdominal margin; the anal lobe black, a deep ferruginous spot in the first median interpace on the margin, with some indistinct white speckles between, the discal band also bordered with white on both sides above the anal lobe.[4]
