sal line of pupa again rises to segment 7 which is about the highest point; 

 the lateral outline also increases from shoulders to middle of: pupa though 

 there is no lateral constriction at all ; the dorsal constriction is broad and 

 gradual. The spiracles of segment '2 are considerably raised, oval and 

 light pinkish-yellow ; the others flush, lighter, small, oval, iiuiface of pupa 

 more or less dull, covered all over with erect, nearly white (some tinged 

 brownish especially at bases), long, slightly curved hairs ; these hairs 

 seeTiingly with many joints each, about as long as one-third the breadth 

 of pupa at middle (or a little less) and not very dense, most numerous at 

 both ends of the body ; the ventrum naked ; the anal end is nearly 

 hemisperically rounded and there are no conspicuous glands — or 12th 

 segment organ-scars. Colour : translucent light yell6w ; abdomen 

 suffused narrowly along the segment-margins with pinkish brown ; segments 

 1-4 and wings spotted with brown-reddish, dorsal line on posterior half of 

 thorax black as well as the lateral corners of segment 5 ; a dorsal, longi- 

 tudinal pinkish-brown line from end to end. Sometimes the pupa is 

 pinkish, the wings, thorax, head and segment 2 soiled whitish-yellow.

Hahits. — The eggs are laid singly in the axils of the leaf-venation 

 on the "underside. The little larva eats out of the egg irregularly 

 uear the top, but does not eat the shell as a rule. It lies at first in 

 the axils ot the veins of the young leaf where it is born and eats 

 the epidermis ; later on eats through the substance but always feeds 

 on 3'^oung leaves, never upon the old ones. It is never at any 

 stage much attended by ants. When very small it lies amongst 

 the fluff of the young leaf-surface which is very densely i softly 

 woolly-hairy. When about to pupate the larva turns pinkish brown 

 and the simple hairs — also some of the flattened ones.^turn dark 

 golden brown ; it settles down very flattened, in some convenient 

 curve of a young or old leaf, often along a midrib acd turns into the 

 pupa, fixed in the usual manner by tlie tail and a bodj^-band tightly 

 against the surface. The butterflies are most niTmerous at the 

 times of young leaf from the month of July to the cold weather in 

 south of the Bombay Presidency. The imago appears within 

 aboiat a week after the pupation has taken place and, generally, 

 eclosion takes place about 10 o'clock in the morning, later on very 

 dull days. The newly emerged insect walks about, slowly for a bit 

 before flying and, at first, only takes very short exercises in the 

 air a few yards or so, settling again to repeat its walking 

 bouts. As a rule it never makes long excursions and never flies 

 high but always keeps to the lower regions of the air not far from 

 the surface of the ground: although its foodplant is a high-climbing 

 species often extending over fairly high trees. The butterfly is fond 

 of settling on bare, more or less dead or dry twigs and is then a 

 fairly conspicuous object, with its wings joined over its back, 

 wliite with lai*ge black blotches. It is not, on the whole, fond of 

 the sunlight arid might be called a species of heavj- jungle and 

 shade, like its congener, Castalius elhion. It has a wet-season and 

 dry-sea3on brood ; really it has broods one after anothu' through
