Under-surface with white fascia distinct across forewings and forming a costal spot on hindwings. The larva is pale ochreous-yellowish; 3-12 with broad dull red transverse bands, on 3 and 4 somewhat interrupted; head yellow-brown; plate of 2 yellow-brown, posteriorly blackish-marked [2] [3] [4] [5] Adults are on wing in July.
