Females have wider, more rounded forewings. The Wings are brown/black. The underside (ventral) contains two rows of small white spots near the apex and a row of bright yellow spots in the submarginal-marginal regions. Females may have an extra spot band along the wing margin. The forewing above (dorsal) has a bright yellow rounded cell spot and a straight band of submarginal yellow spots near the apex. The hindwing below is black with a marginal frosting of violet-white and a bold white spot along the upper margin. The upperside of the hindwing is black with a yellow border. The antennal clubs are bent near the tip.
