The forewings are dark purplish-fuscous with a somewhat irregular straight transverse whitish-ochreous line at two-fifths, somewhat expanded on the costa. There is a small whitish-ochreous spot on the costa at four-fifths, where a fine somewhat curved line of scattered whitish-ochreous scales runs to the dorsum before the tornus. The hindwings are grey.
