The upper forewing has a small white spot at the end of the cell, a complete series of equal sized marginal white spots in regular row and a terminal series of spots decreasing in size towards the apex. The upper hindwing has a discal series of arrow shaped white spots. It also has a submarginal series of elongated white crescent shaped markings. There is a white fringe between the veins. The outer halves of wings have a dusting of yellowish brown scales.
