The hindwings are orange with a postmedian transverse crenulate dark band beyond which is a similar lunate one. Females have chocolate-rufous-brown forewings with yellow nervures and a round white spot below the cell in the basal one-third of the wing. There is a slightly curved median darker chocolate band and a postdiscal row of eight intranervular wedge-shaped white patches. The hindwing ground colour and median band are similar, but with a postdiscal row of wedge-shaped golden-yellow patches.
