The fore-wings are nearly alike in both sexes, being but very 

 slightly emarginated in the male, with the tips acute ; wings rich yel- 

 low, with several livid or reddish patches near the base, followed by a 

 much-waved livid striga ; in the middle of the wing is a moderate- 

 sized ocellus, the centre vitreous, outwardly edged with black, sur- 

 rounded by a livid ring, and this by a white circle, outside of which 

 is a narrow purplish or reddish ring. Connected with the outer edge 

 of the ocellus is a slender, very strongly denticulated dark brown line ; 

 beyond this is a nearly straight purplish brown striga, extending from 

 the fore-margin, where it is rather angulated and extending to the 

 middle of the inner margin ; beyond this line the outer margin of the 

 wing is marked with confluent livid or reddish patches, the margin 

 itself being of the same colour except at the tip. 



The hind-wings are more or less tinged with red at the base, fol- 

 lowed by an angulated dark denticulated striga arising from the anal 

 margin. In the middle of the wing is a large brilliantly coloured 

 ocellus ; the pupil is black, with a slender vitreous line towards the 

 base ; the iris is livid, outwardly shaded to red, surrounded by a 

 slender white circle and this by a red ring. From the inner margin 

 of the eye runs a dentated brown line to the anal margin, and behind 

 it is a waved or dentated brown striga, the apical portion of the wing 

 being coloured as in the fore-wings. The thorax is yellow, with the 

 head, collar and legs livid brown. The wings are much less brilliantly 

 coloured on the underside, and the great ocellus of the hind-wings is 

 almost obliterated. The vitreous part of the ocellus of the fore-wings 

 is much smaller in the male than in the female; and the ocellus of the 

 hind-wings in the female is much more vividly coloured than in the 

 male. 



The antennae of the males are 32-jointed with forty-eight rays on 

 each side, the two apical rays of each joint being rather shorter than 

 the two basal ones. 



The palpi are short, but distinct and broad ; the basal joint with 

 scales extending beyond the second joint. The antennae of the female 

 are 37-jointed, the rays being about three times as long as the thick- 

 ness of the antennae, and the two apical rays of each joint being quite 

 short.
