"Adults: Above, the male is mostly black but pale azure blue on the baso-dorsal area of the forewing and the whole of the hindwing minus the apical area. It has the appearance of a deep lustrous purple in a side light. The female is pale brown and has whitish tornal areas on the hindwings marked with black marginal spots. Beneath, both sexes are white with apical areas on both wings shaded ochreous brown, more broadly so on the forewings. The cell-end bars are darker ochreous brown, and each wing has a narrow post-discal line and an obscure submarginal line. Each hindwing has a small black spot at base of space 7, a large black spot in space 2 and another on the tornal lobe. There are two pairs of white tails with the pair at vein 1b rather long, about twice as long as the pair at vein 2."
