The markings are blackish, consisting of a somewhat irregular streak along the costa from the base to four-fifths and a semi-oval spot on the inner margin at one-third, beyond which the inner margin is ochreous yellow.

The hindwings are ochreous yellow with a dark fuscous irregular fascia from the apex towards two-thirds of the inner margin.
