There is an indistinct dark fuscous dot beneath the costa before the middle and a small subquadrate discal spot obscurely outlined with cloudy blackish beyond the middle. There is also a hind-marginal row of cloudy blackish dots. The hindwings are pale greyish-ochreous, irregularly irrorated with fuscous. There is an obscure fuscous discal dot.
