The forewings are white with a violet-grey basal patch suffusedly spotted with dark fuscous occupying one-fourth of the wing, the edge slightly oblique and with two small cloudy fuscous spots on the dorsum towards the middle. There is a black dot on the lower angle of the cell, and a fuscous one on the upper, as well as a curved series of several small indistinct fuscous marks running from the costa beyond the middle to the dorsum before the tornus and a somewhat sinuate indistinct fuscous shade from five-sixths of the costa to the tornus. A cloudy dark fuscous spot is found on the apex and upper part of the termen. The hindwings are ochreous-grey-whitish
