The forewing has a broad, angled medial band, with a pale area basal to it, with a similar, but more sinuous band on the hindwing. The hindwing postmedial is fine, pale, shallowly but regularly curved. Translucent areas occur in the centre of both fore- and hindwings just interior to the postmedials.
