Imago. —Male. Upperside black. Forewing with more or less indistinctly 
defined greyish-white scaled longitudinal streaks within the cell, these streaks in 
some specimens ending before its apex in a more or less apparent or well-defined 
whiter oblique bar; beyond is a discal transverse series of more or less defined 
whitish-grey scaled spots, the lowest being generalU elongated and divided by a 
black line, followed by a submarginal series of similar-scaled lanceolate spots. 
Hinchving with a more or less apparent whitish-grey scaled small divided spot, or a 
distinct short narrow streak before the apex of the cell, a discal series of white 
irregularly-quadrate shaped spots, and then a sub marginal row of broad lunularly- 
lanceolate spots ; base of abdominal margin broadly greyish-white, the anal area 
being broadly bright yellow ; the costal interspace also bright yellow. Underside. 
Foreivmg duller black, the white markings more prominent, the apical spots being 
yellow. Hindwing vinaceous-black, the broad cell-streak, basal costal spots, and 
submarginal spots bright yellow, the discal spots white, the three median being 
partly yellow and the anal border broadly yellow. 
Female. Upperside duller black. Forewing with markings similar to the 
male, except that they are less distinct, and the cell apical-bar only apparent. 
Hindwing also similar to the male, with an elongated cell-streak and full-sized 
discal spots, basal costal interspace paler, and the anal area much less suffused 
with pale yellow, or the cell-streak is short and apically restricted or more or less 
obsolete, the discal and submarginal spots smaller, and the anal area almost or quite 
white. Underside similar to the male. Occasionally a male occurs (see fig. 2), in 
which the basal costal interspace and the anal area of the upperside, and all the 
underside markings are red, and a female (fig. 2a) with dark ochreous-yellow basal 
costal interspace and whitish anal area of the hindwing on the upperside, and 
similar dark ochreous-yellow markings on the underside.
