180 Mr. G. F. Mathew’s life-histories of 
extremity of the leaflet, which generally rests upon or 
overlaps another, spins the edges of the two together, 
and so forms a little tent, from which it issues forth 
from time to time to feed, usually eating the leaflet from 
its tip towards the base. As it increases in size it forms 
a larger domicile, fastening the edges of the leaves 
together by little cables of united strands of white silk 
fixed to pads of silk placed about half an inch apart. 
The full-grown larva is 40 mm. long, cylindrical, 
rather elongate and depressed, and tapering towards the 
head; head considerably larger than the second segment, 
flattened and porrected, and somewhat cordate, light 
pinkish grey, with black margins to face and a v-shaped 
mark in centre, and with a longitudinal black mark 
between mouth and base of y; general colour of larva 
transparent slaty greenish grey, anterior and posterior 
segments rather paler ; a darker pulsating dorsal vessel ; 
upon the tenth segment there are two golden-yellow 
spots, lying just beneath the skin, and showing through 
on each side of the dorsal vessel (these spots are caused 
by some internal organs) ; anal segments sparsely clothed 
with fine white bristles; spiracles pale yellow; whole 
surface more or less finely and transversely wrinkled ; 
lateral skinfold well-developed. Just before its final 
change it assumes a bluish green or leaden hue. _ When 
full-grown it spins the edges of the leaves more firmly 
together, constructs a light silken cocoon, and therein 
changes to a pale reddish-brown chrysalis, which is 
thickly powdered with a whitish-purple bloom. ‘This 
powder exudes from beneath the ninth, tenth, and 
eleventh segments of the larva as it lies quiescent pre- 
paratory to its next change. The chrysalis, which is at 
first somewhat transparent and pale greenish yellow, is 
from 25 to 80 mm. long, cylindrical, and tapers towards 
anal extremity; thorax much broader; head and eyes 
prominent; thinly clad with short pale reddish-brown 
and slightly-curved bristles, those upon the head and 
thorax pointing forwards, while those upon the abdomen 
point backwards ; just above and behind the eyes, upon 
the suture dividing the head from the thorax, there is a 
conspicuous oval reddish-brown tubercle; the sheath of 
the haustellum extends beyond the wing-cases as far as 
the base of the eleventh segment, and is faintly tinged 
with rosy. A day or two before the insect emerges the
