The plical stigma is blackish and there is a triangular brown patch resting on the termen from near the apex to the tornus and its apex reaching in the disc to the end of the cell, the upper part yellow brown and edged posteriorly with some dark fuscous scales and anteriorly with a semi-oval blackish spot, preceding its apex a dark fuscous dot in the disc. There are three or four indistinct dots of dark fuscous irroration just beneath the costa towards the apex. The hindwings are ochreous whitish with a short dark grey almost marginal streak around the apex.
