follows : —two on the 2nd, four on the 3rd, and two on the 10th, 
segment. The legs are black, and the white on the body shows up 
distinctly in contrast with the black transverse lines. The 3rd and 
10th segments are almost entirely black. 
After the second moult two more long black hairs appear; they 
are situated on the 11th segment and incline backwards. The 
general appearance is much the same as after the first moult, black, 
however, predominating. The segments appear to be divided by 
transverse white lines when viewed laterally. 
After the third moult two more long hairs appear on the 12th 
segment, projecting over the anal portion like a pair of tails. There 
is a lateral row of eight or nine white spots from the 3rd to the 11th 
segments, those just over the first pair of abdominal legs being 
larger, those on the other segments being mere specks; these spots 
appear on all the larve after the third moult. There are also from 
two to four reddish spots on the 1st segment, which is otherwise 
black ; sometimes there is more of a pattern than decided spots. 
As will be seen from my illustrations, the larvee are apt 
to vary a good deal after the third and fourth moults. 
The body generally is black and white, but irregularly and 
differently placed in different larvee. Generally there is a transverse 
wavy black line about the middle of each segment edged with white 
anteriorly; sometimes there are irregular white areas edged with 
black, and occasionally the ground colour is greyish-lilac with broad 
black transverse lines, with white spots. The thoracic legs are 
yellowish-red, the same colour as the head, and the others whitish 
or flesh-coloured. The number of long black hairs on the body may 
differ in many larvee at the fourth moult ; two long hairs appear 
generally on each of the segments from the 4th to the 9th, hitherto 
only covered with a few fine hairs, in addition to the others on the 
other segments—these are straighter and finer and project laterally, 
the others are inclined to curl at the tips. 
PUPA. 
The pupa is light yellowish-brown, glossy, with black dots and 
lines ; the lines on the thorax just where the wings of the future 
insect are encased are in imitation of neuration marks. It lies inside 
a roomy cocoon of yellowish-red silk, which is like a network and 
through the meshes of which it can be seen. Two leaves of the creeper 
are fastened one above the other, and the cocoon formed between. 
The transformations from the egg to the imago occupy
