titan. It has also been found on Milhttia atropurpurea 

 Benth., Macuna pruriens DC, Dalbergia volubilis Roxb., 

 all large climbers, and on Cassia fistula Linn., the Indian 

 laburnum. The larva eats the cast skins after moulting. 

 The larval growth takes about a month and a half. 



This species is even more common than C. bilineata, and the 

 larvse are very plentiful during the monsoon months, usually 

 feeding on Xylia in jungle country and on Pongamia in open 

 country. The moth never comes to light, and we have 

 not observed it feeding. We have occasionally found moths 

 in the jungle, but always paired. Bred females attract wild 

 males readily, and we have bred several series from eggs 

 obtained thus. The only occasion on which we succeeded 

 in getting bred pairs to mate was when a whole brood of nearly 

 200 specimens from one female were kept together in a large 

 cage, and three or four pairs mated. The moths did not feed 

 before mating, but they flew about, the males flying a great 

 deal more than the females. The latter sat for days sometimes 

 without moving. The males are always smaller than the 

 females.

Imago. — <£?. Underside of femora, inner side of anterior 

 tibia and tarsus, upper side of mid- and hind tarsi and of 

 antenna pink, upperside of mid- tibia and outer side of all 

 tibiae blackish ; hind tibia of <$ longer than, of $ as long as, 

 the first tarsal segment ; spurs longer than in the other 

 species of Clanis, the short ones over half the length of the 

 long ones, those of the apical pair of hind tibia not so widely 

 different in length as in other species, the longer one more 

 than half the length of the first tarsal segment. Wings more 

 elongate than in any other species of this genus. Distal margin 

 of fore wing in $ longer, in $ very little shorter, than the inner 

 margin ; the lines of lunules of the fore wing on the whole 

 more strongly marked than in bilineata, with which the species 

 has been confused by Leech and Hampson : there are in some 

 specimens four such lines between the cell and the post- 

 discal line which begins at the apical patch ; the black area 

 of the hind wing is more extended than in bilineata. Expanse :
