The forewings are dark red brown, suffusedly mixed with dark purplish fuscous and with a short indistinct light reddish-ochreous transverse mark from the costa almost at the base. The plical and second discal stigmata are small, indistinct and blackish and there is a small indistinct spot of ochreous suffusion on the costa at three-fourths. The hindwings are rather dark grey.[4] Adults are on wing from October to May and in August.
