The forewings are grey-whitish with the costa narrowly grey from the base to four-fifths, darker towards the base. There is a spot of grey suffusion below the middle of the disc, one on the upper angle of the cell, and two small ones towards the lower angle, as well as a rather broad subterminal fascia of grey suffusion, interrupted on the veins. There are some cloudy dark fuscous marginal dots around the apex and termen. The hindwings are grey.
