LARVA! AND PUPA5 OF BUTTERFLIES. 363 



black soil. The larva may be distinguished from both the List by a 

 pinkish band encircling the body at the seventh segment, in which 

 ther< is an insular patch of the ground-colour on each side. The 

 ground-colour is richer than in 0. niinos, and the processes are all red. 

 The pupa is scarcely to be distinguished from that of /'. kedtor,

In these the form of the larva is well marked and easily recognis- 

 able. From the head, which is moderately large, the body increases in 

 thickness rapidly to the fourth or fifth segment, and then tapers more 

 gradually down to the tail. There are either three or four pairs of 

 short sharp spines, one on the second and one on the 4th segineut, 

 sometimes a minute pair between these on the third, and a pair en the 

 last segment. These spines are very prominent in the young larvae, 

 but decrease with each successive moult. There are no other irregu- 

 larities, and the whole body is soft and very smooth. The pupa is 

 smooth and regular, with the exception of a single frontal horn, or 

 to be more correct, pointed process, rising from the thorax above the 

 head. In habits these larvae are very different from those of the last 

 group. They are extremely shy and cautious, resting motionless 

 most of the day on the upper side of a leaf, along the midrib, with 

 their heads towards the stalk. The leaf on which they rest is usually 

 carpeted with silk. They cat little and grow slowly, which appears 

 to be generally a characteristic of the larvoeof those butterflies y\ bieh 

 have a stout thorax and strong flight.

 The form of the larva has already been described. It has four 

 pairs of spines. The colour is at first smoky-black, but at the lit 

 moult becomes a light, clear, green, faintly marked with wavy lines 

 of a darker shade. The pupa is normally of a pale watery-green, the 

 horn being broadly tipped with rusty-brown, which continues in an 

 irregular line along the outside edge of the wing-cases. The larva 

 feeds on the Custard Apple (Anoiia squamosa), the " Ramphul" ( I. 

 reUcutaia), and others of the genu-, and also on the "Ashok" {Goal 

 teria hngi/olia). It is often difficult to hud, and must be looked feu
