The forewings are whitish-grey with scattered dark grey scales in the disc. The stigmata is indicated by dark grey dashes. The plical is rather obliquely before the first discal and there is a cloudy spot of dark grey suffusion on the base of the costa, an oblique spot at one-fourth and a semifusiform costal streak from one-third to three-fourth. There are also two or three fine dashes of blackish irroration towards the costa posteriorly, and some undefined dots on the termen. The hindwings are grey.
