The forewings are dark fuscous, variably marked white and brassy-yellow, especially a number of irregular confluent markings occupying the dorsal area beneath the fold, and a dark blotch on the costa at one-third, more or less outlined by irregular markings, but all very variable. There are three or four white marks posteriorly converging to a small black subapical spot edged anteriorly and above with silvery. The hindwings are light grey.
