The forewings are ochreous-white, with some irregular fuscous sprinkling, especially beyond the cell. There is a slight dark fuscous mark on the base of the costa and the second discal stigma is blackish. There are three oblique blackish costal spots, the first at one-third, small, the second in the middle, moderate, the third at four-fifths, elongate-semi-oval, from the end of this a somewhat curved dentate fuscous shade near the termen to the tornus. There is also a marginal series of black dots around the apex and termen. The hindwings are light grey with the terminal edge suffused darker.
