Forewing with six transverse series of yellow-ringed black spots, each series curved, irregularly disposed and variable as to size and number, the postmedial series bifurcating towards the costa. Hindwings also scarlet with one black spot at end of cell, another spot at origin of vein 2, another spot at its middle, and a submarginal series. There is a few small spots on margin, all these being somewhat variable. Larva purple-black with a few dorsal hairs. Head and a lateral line from 4th to 10th somites are reddish.
