There is a small triangular dark fuscous spot on the middle of the costa and a suffused triangular dark fuscous blotch extending along the apical third of the costa, the costal edge between this and the preceding spot whitish. There is also a terminal series of elongate blackish dots. The hindwings are ochreous-yellow, the dorsal two-fifths grey.
