Upper side : primaries bright yellow, with a large deep-orange patch on the 
disk, which reaches neither the costa nor the base, and occupies about one-half the 
space inside the border ; the border is broad, black, crossed by the yellow nervures 
nearly or quite to the margin, and resembles C. Eurytlieme in the outline of its 
inner edge ; discal spot small and black ; edge of costa rose-red. 
Secondaries lemon-yellow with a pale orange patch which is confined to the 
outer limb, reaching neither the costa nor abdominal margin ; the border narrow, 
with a very even inner edge, also crossed by the yellow nervures; discal spot large’ 
deep-orange ; fringe of both wings long, rose-red. 
Under side : primaries same yellow, the basal half pale-orange ; costal mar- 
gin sprinkled with fine black scales ; between the nervules three or four sub-mar- 
ginal brown points or clusters of scales ; discal spot as above. 
Secondaries more greenish, covered uniformly with fine black scales ; an ob- 
solete sub-marginal row of brown points ; discal spot small, round, silver-white, in 
a reddish-brown circlet about which are a few scales of same color ; a few rosy 
scales at the base ; fringe and costal edge of each wing rose-red : palpi pale yellow ; 
legs and antennae rosy ; club blackish. 
In three specimens out of four there were no traces of the sub-marginal points.
