Miskin's original description:

Upperside: pearly white, with slightly opalescent hues. Primaries: With costa, apex and outer margin widely dark brown; small black transverse line at termination of cell. Secondaries: with the veins brown; outer margin narrowly bordered with brown, gradually decreasing to apex; a submarginal line of white from apical to anal angle; second and third median branches terminating in well developed tails; the first median and submedian forming points but not extended; between the two tails a large crescent of orange surmounting black border, and in the angle a patch of orange; between the orange patches black crowned with white, and above all a faint margin of brown.

Underside: greyish-white. Primaries: with outer edge of Aving dark brown; a marginal band of pale brown or fawn colour; an inner line of faint brown; a transverse interrupted streak of dark brown; three short discal streaks within cell. Secondaries: With edge, band, and transverse streak, as in primaries, the latter being elbowed twice, opposite the tails; a dark speck near base; a short dark streak in cell, one near costa, a longer one at termination of cell; orange spots as on upper side, but rather larger.
