The wingspan is 33–35 mm. The forewings are dark purplish fuscous, irregularly strewn with whitish-ochreous scales and with small indistinct cloudy dark fuscous spots in the disc at one-fifth, and before and beyond the middle. There is a cloudy spot of pale irroration (sprinkling) on the costa at three-fifths and a terminal series of pale ochreous connected lunulate marks alternating with cloudy dark fuscous dots. The hindwings are dark fuscous, rather lighter anteriorly.[2]
