Forewing: veins black apex and termen black, the inner margin of that colour extended in an irregular curve from middle of costa to base of terminal third of vein 4, thence continued obliquely outwards to the tornal angle interspaces 6 and 9 with short narrow greyish-white streaks of the ground colour that stretch into the black apical area but do not reach the margin a short black subterminal bar between veins 3 and 4 and another, less clearly defined, between veins 1 and 2. Hindwing: veins 4 to 7 with outwardly dilated broad black edgings that coalesce sometimes and form an anterior, irregular, black, terminal margin to the wing. Underside, forewing: white, the veins broadly margined on both sides by dusky black costal margin broadly and apex suffused with yellow subterminal black bars between veins 1 and 2, and 3, and 4 as on the upperside but less clearly defined. Hindwing entirely suffused with yellow, the veins diffusely bordered with black a more or less incomplete, subterminal series of dusky spots in interspaces 1 to 6 more often than not, the spot in 5 is absent a conspicuous chrome-yellow spot on the precostal area.
