A2 
minutes. The female moth lives longer than the male; the latter dies after copula- 
tion, which takes place more than once if he is disturbed at first. The females begin 
to drop their eggs the second or third day after birth, often before impregnation, and 
die after all are laid, z.e. in five or six days. 
“On the 17th of June the first batch of worms made their appearance, and on 
being placed on the young leaves of the Badaam or country almond (Zerminalia 
catappa), began to feed greedily. The leaves are changed every morning, and kept in 
a tumbler of water or damp mould, placed inside a gauze-covered box. Care had to 
be taken, when the worms got large, to keep them supplied twice a day with fresh 
leaves, morning and evening, and not to put too many together. I lost a large 
number, more than half-grown, from overcrowding. The heat thus generated caused 
them to get quite putrid, and one dead one in this state, unless speedily removed, will 
cause quite an epidemic amongst the rest. 
“ June 17. The tusseh worm when born is about one-fourth of an inch in length; 
body hairy and of a chrome-yellow colour; head and tail black, a tuft of black hair 
on the neck, just behind the head, and another smaller tuft of the same colour near the 
tail; a row of minute black spots down the middle of the back connects these two; 
there is also a row of similar black spots down either side above the legs. Head and 
body fringed with yellow hairs. Head black and shining, and large in proportion to 
body. 
“June 21. The worms born on the 17th are now nearly an inch long, and have 
lost the brownish tinge they had when first born. The colour is now a light green, 
covered with little light green spines, each spine terminating in a tuft of light- 
coloured hair. The head at first is black; behind it, and separated from it by a little 
green band, is another patch of black; there are two little black spots or spines on the 
second segment, and one on the anal segment; these spines are tufted with black hair. 
The row of black spots down the back are of a bluish tinge, and those down the sides 
appear to be the spiracles. 
“June 21. (Second stage). The ground colour of the worm is now a bright 
yellowish green; he is still about an inch in length, but thicker and broader, especially 
about the head and shoulders. The black spots down the centre of the back have 
entirely disappeared ; instead, on either side of where they were, are two rows of yellow 
spines or dots, light yellow at the base, orange-yellow at the tips, and surmounted by 
star-shaped tufts of black hair, the pair on the second segment the largest. The head 
and prolegs brown. Four separated black spots, in place of the black patch on the head. 
The row of spiracles is scarcely visible; on each side of them a row of yellow spines 
has appeared, making, with those on the back, altogether six rows of these spines from 
head to tail parallel with each other, and covered with tufts of hair. A brownish tinge 
on last pair of legs and lower part of anal segment, the latter covered with hairs. 
“ June 25. (Third stage). The caterpillar is now a little more than 13 inch long, of 
a beautiful light green colour, with a yellow stripe down each side from the third seg- 
ment to the tail, which has a brown triangular patch on each side, edged with light 
yellow. The spots on the rows of spines on the back have changed to a glittering 
golden yellow colour, the pair on the second segment surmounted by a star of black 
hairs. The spots on the two rows down each side have also changed; they are now 
orange at base and sky-blue at tips. Prolegs and head light brown, as also are the 
hind legs, with small black spots and hairs above them. A yellowish collar of skin 
round the head, with its attendant spines, which are yellow on the capital segment,
