Imago. — Male. Upperside blackish-brown, with a distiuct yellowish tinge, the 

 markings on both wings dark chrome-yellow. Forewing with two streaks in the cell 

 near its end, the lower one on the lower side, about one-third the length of the cell, 

 the upper one short (almost a spot) attached to its upper outer end, two sub-apical 

 spots, the upper one minute, two sub-quadrate discal spots, obliquely placed, close 

 together, near the bases of the median interspaces, separated from each other by the 

 second median nervule, all these spots semi-transparent ; an indistinct dull streak 

 along the basal half of the costa, another in the basal third of the interno-median 

 iuter.space, and another on the basal half of the hinder margin. Hindwing with a 

 discal j^atch of streaks, one in each of the median interspaces, occupying more than 

 half their length, and a long streak in interspace 4, which runs well into the cell, all 

 three streaks merely divided from each other by the blackish-brown veins, and between 

 this patch of streaks and the abdominal fold the wing is covered with long, dull, chrome- 

 yellow hairs forming two obscure streaks ; there is also a chrome-yellow spot above the 

 cell end. Cilia of both wings cinereous. Underside. Foreicing with the upper half 

 more or less smeared with chrome-yellow, the lower half blackish, the spots as on the 

 upperside ; a sub-marginal series of pale yellowish spots from the apex to the first 

 median interspace. Hindwing entirely dull, pale chrome-yellow, the outer margin with 

 some grey spots ; the costa with some grey scales, and a few indistinct grey dots in 

 some of the interspaces. Antennae black, club white on the underside, orange-red at 

 the tip ; palpi, head and body above concolorous with the wings ; head and shoulders 

 with some yellowish hairs, a thin yellowish collar, abdomen with whitish hairs ; on the 

 underside the palpi and pectus are yellowish-white, thorax and abdomen yellowish- 

 grey ; legs brown above, yellowish beneath. 



Female. Upperside blackish-brown, with the same yellowish tinge. Forewing 

 with the spots semi-hyaline and of a chrome-yellow colour, but paler than they are in 

 the male, and similarly placed with the exception of the cell spots, there being only one 

 near the upper end of the cell, the lower streak being absent, and there is an extra spot 

 in a line with the discal pair, on the middle of the sub-median vein, all the yellow 

 streaks entirely absent. Hindwing without marking.s. Underside. The chrome-yellow 

 on both wings is replaced by a yellowish-rufous colour. Forewing with the spots as 

 on the upperside. Hindwing with four pale sub-costal spots, a discal, nearly straight
