    The adult moths are brown, with a dark mark near the middle of the inner margin, and sometimes yellow markings at the tornus of each forewing. The wingtips are hooked and the inner margin recurved, of each forewing. The hindwings are plain brown, fading toward the bases. The females are more brightly coloured than the males. The wingspan is about 4 cms.
