Notes         :
The largest member of the group, easily distinguishable by the yellow markings on the underside.

Male: Upperside creamy-white. Fore wing with narrow black (sometimes white-dusted) apical area, which extends as a narrow marginal border from vein 4 to vein 2. Three white subapical spots in cellules 5,6 and 8, the lower one being within the black border. Two white spots close to the margin in 3 and 4. Some grey-black dusting at the base. Hind wing with a shadowy grey-black marginal border from the anal angle to vein 5. Some grey-black basal dusting.

Underside fuscous-black. Fore wing with proximal half of cell tinged with yellow, the submedian area grey-white. A white discocellular spot. Three subapical spots as above, yellow or white, the two lower ones with distal prolongations. Four small white submarginal spots in 1b,2-4, each touching the margin by a distal prolongation. Hind wing with yellow costal margin. A large yellow median patch, broad on the inner margin and becoming narrower to vein 4, not entering the cell. Proximal area dusted with yellow. Six submarginal spots, the two anterior ones yellow, the others white, of triangular form with their apices touching the margin.

Fringe of both wings white.

Female: Upperside black with creamy-white submarginal spots, and grey proximal dusting. Fore wing with six spots placed as in the male but with their apices not usually touching the margin; two marginal dots in 1b and 1c. Hind wing with six spots formed as in the male. The inner margin is greyish-white.

Underside fuscous black. Fore wing marked as in the male, but the submarginal spots are farther from the margin and larger than on the upperside. Hind wing with a yellow median patch which is narrower and less distinct than in the male and is merged with the basal yellow dusting. the submarginal spots are much larger and more sharply defined than above; the four posterior ones are deeply toothed on the proximal edge, and are usually tinged with yellow.

Fringe of both wings white between the veins, and fuscous at the veins.
