C, aoris and C. olivacea are distinguished from all the other Indian species by their large 

 size, and by the males as well as the females having the apex of the forewing distinctly truncated. 

 The females too are more widely different in both than in the remaining Indian species of this 

 genus. They are confined to North-Eastern India and Burma.

Description : Male. Upperside, both -winos bright fulvous, powdered with dusky 

 at the base. Forr.oing with the apex strongly truncated, the outer margin slightly emargi- 

 nate and sinuous; the disco-cellular nervules slightly defined with dusky on either side ; 

 a very irregular and somewhat indistinct discal fuscous line, beyond which are a series 

 of diffused, very indistinct, often obsolete fuscous rounded spots between the nervules, 

 the margin narrowly black, widely black at the apex, two submarginal lunular black lines, 

 of which the outer one is the more prominent and becomes merged in the black apex. Hind- 

 ■wing with a very irregular discal black line, with the usual whitish spot on the middle of 

 the costa ; a discal series of six round black spots one in each interspace except the discoidal ; 

 two deeply engrailed submarginal lines, the outer one the darker, a marginal narrow nearly 

 straight black line : all the veins defined with black on the disc. Underside, both wings 

 much paler, all the markings of the upperside more or less obliterated ; a common 

 discal whitish fascia, narrowest in the middle of each wing, its outer edge very straight 

 and even, its inner edge irregular, defined by a pair of dark lines enclosing a pale yellow line ; 

 submarginal and marginal yellow lunular lines, divided and inwardly bounded by whitish 

 lunules ; a pale brown subbasal streak. Forewing with a whitish patch at the apex. Hindxving 

 with the six round black spots of the upperside but smaller. Female much darker, the 

 ground-colour of the upperside ochreous, thickly irrorated throughout with fuscous scales. 

 Markings as in the male, but heavier and darker throughout. Underside pale buff, washed 

 throughout with obscure violaceous ; the markings of the outer half more obscure, of the inner 

 half more prominent and wider than above, the discal fascia less distinct, almost concolourous
