The forewings are pale violet-grey with whitish reflections, irrorated grey and with the costal edge pale grey-yellowish, near the base dark grey. The plical and second discal stigmata are small, cloudy and dark fuscous and there is an irregularly sinuate fuscous shade from beneath the costal edge at two-thirds, passing behind the second discal, obsolete towards the dorsum. There is a rather curved connected series of cloudy fuscous dots from the costa at four-fifths to the tornus, hardly sinuate near the costa. There is a marginal series of blackish dots around the apex and termen. The hindwings are pale whitish-yellowish, yellower
