Imago. —Male. Upperside black or fuliginous-black ; cilia fuliginous. Forewing 
with pale fuliginous or greyish-fuliginous streaks bordering the outer veins, these 
streaks terminating uniformly at some distance before the exterior margin; similar 
pale short streaks also extending from within end of the cell. Hindwing with a 
lower-discal series of three, or four, white or oclireous-white spots, which are usually 
small and short and disposed in a curve at some distance beyond end of the cell ; at 
the anal angle between the lower median and submedian is a contiguous more or less 
irregular-shaped spot, this latter spot being more or less elongatedly-ocellate with a 
black centre and of a sullied-white or crimson colour, or is whitish anteriorly and 
crimson posteriorly; beyond is a submarginal series of five dusky-scaled lunules, 
which are either dull or bright crimson and sometimes dull oclireous. Underside. 
Morewing duller fuliginous-black; the vein-streaks much paler. Hindwing intense 
black ; the discal white spots as on upperside, and with six submarginal pale or 
bright crimson spots larger and broader than on upperside, the upper spot being 
placed in the costal interspace ; the anal spot also bright crimson. Thorax and 
abdomen above black; front of head, palpi, collar, sides of thorax beneath and 
abdomen bright crimson ; abdomen beneath with black segmental bands; antennae 
and legs black. 
Female. Upperside duller coloured. Forewing olivescent fuliginous-black ; the 
vein-streaks less prominent and duller fuliginous. Hindwing olivescent-fuliginous 
basally, black externally; the discal white spots, positioned as in the male, are 
similar in shape but somewhat larger and broader; the submarginal lunules also 
larger, paler and duller coloured. Underside similar to the male.
