Fore wing: a dusky brown lunular line on the discocellulars; two subcostal spots above the cell, one on either side of the discocellular lunule; a very strongly curved discal series of five spots, of which the posterior three are somewhat lunular in shape and placed obliquely en echelon, the next above these hook-shaped, the anterior spot round; both the subcostal spots and the spots of the discal series are black, each narrowly encircled with white; beyond these are inner and outer subterminal dusky lines, which anteriorly are continuous, posteriorly somewhat broken and macular, followed by a very conspicuous jet-black anticiliary slender line. Cilia greyish white, traversed by a medial transverse blackish-brown line. Hind wing: with the following small white-encircled black spots: a subbasal transverse series of three, followed by a highly curved series of eight spots, that curve across the disc of the wing to the costa and along the latter towards the base; discocellulars with a dusky short lunular line as on the fore wing; terminal markings and cilia similar, but the outer and broader subterminal line more broken and macular than on the fore wing.
