LARV.E AND PUPsE OF BUTTERFLIES 353 



butterfly of the summer form. The rest came to grief. There were 

 a good many ants on the tree, which seemed to take the same interest 

 in the larvae as they take in Aphides of all sorts, and also on the 

 sacehariferous g-lands at the bases of leaves, but we could not see that 

 the larvae were in any way helped by the ants, or dependent on them. 



47. Tanccus theophrastus, Fabricms. 

 This also is carefully described by Mr. de Niceville. "We have 

 reared it in Bombay on Zizyphus jujuba, the "Bore" or "Bear" tree. 



48. Tarucus plinius, Fabricms. 



We saw this species in Bombay laying its eggs on a leguminous 

 plant with yellow flowers, which shoots up during the rains to the 

 height of six or seven feet and dies immediately after, and which Ave, 

 with sucli skill in botany as was at our command, identified as 

 Sesbania aculeatq. The leaves of this wretched plant wither ten 

 minutes after you pluck them, but we succeeded in rearing one cater- 

 pillar by keeping it in a small, air-tight box. It is described in our 

 notes as green, and of the usual wood-louse form, with a dorsal ridge 

 of minute protuberances. The pupa was greenish, smooth, not a 

 quarter of an inch long, and closely attached to the bottom of the box. 

 The pupa state lasted seven days. Seven, ten, and fourteen days 

 appear to be the commonest pupal periods. 



49. Cast alius decided, Hewitson. 

 This feeds on the tender leaves of the " Chorna" {Zizyphus rugosa), 

 and we reared a good many in September and October. The larva 

 is pale green, and of the usual wood-louse form, with the head concealed 

 under the second segment. The whole body is more or less pubescent, 

 and there is a fringe of longer hairs on each side. The pupa is short 

 and stout, constricted between the thorax and abdomen, clothed with 

 short hair, closely attached by tail and band to any convenient surface ; 

 colour ochreous, mottled with brown. 



50. Iraofa timokon, Stoll. 



We got five or six of these in September, feeding on the bark of 



Finis glomerata, and when that failed, on each other, for they are 



horrible cannibals. They never ate a leaf. The larva is very stout, 



but is much constricted in the middle, so that the circumference is
