Original Description - Male: Joicey & Talbot - Entomologist lvi -1923 : "Upperside white. Fore wing with broad black apical area and costa narrowly black. Hind wing with broad black distal area, in cellules 2 and 3 with distinct triangular prolongations. The black dusting along the edge of the white area is more uniform but less strongly present than in isse echo. Underside with fuscous-black ground-colour. Fore wing with apical area somewhat as in echo but broader; proximal area pale yellow, paler still posteriorly. Five small submarginal spots in 3, 4, 5, 6 and 8, the two anterior ones the larger. Hind wing with a submarginal series of six yellow spots, the one in 6 the larger, the others uniform and somewhat linear. Base to near middle of cell and cellule 8 dusted with yellow, inner margin yellow."

Hill Mus. i, pt 2 - 1922 : "Upperside of fore wing with white area more extended than in echo, reaching the end of the cell, and curving outwards by the origin of vein 4 to the tornus. Hind wing with white basal half reaching beyond the cell. Underside of fore wing with sharply-defined yellowish-white areas as above. Five pale yellow submarginal dots, those in 2 and 4 farther from the margin than in echo. Hind wing with basal yellow area not well defined, but reaching base of vein 6. Submarginal series of yellow spots placed a little farther from the margin than in echo."
