Underside dark brown, with the veins and longitudinal streaks between them greyish green, the brown showing only along each side of the veins; posterior margin of forewing broadly pale vinaceous; exterior margin of both wings defined by a brown line. Third joint of palpi and edge of sides brown, the rest yellow. Thorax, legs and abdomen beneath orange yellow.

Female. Expanse 2.3 inches. Upperside very dark glossy bronzygreen, shading off into glossy indigo-blue at the apex and outer margin. Underside with the markings and ground-colour darker than in Sikkim males; forewing with a pale green spot in the second median interspace, with a larger one in the interspace below it, in the male these spots are merged in a large patch of the ochreous ground-colour from the inner margin. The green markings everywhere more restricted and of a darker shade than in the male.
