The postmedian line is made up of three outward arcs, partially lined on the distal side by dark scales and on the proximal side by pale ones. The reniform is partially outlined with dark scales in a crescent. The terminal line is comprised of a series of fine dots between the veins. The hindwings are white, with the discal spot and veins faintly marked with darker scales. Sexes similar, the female slightly larger and with darker hindwings.
