148 Mr. G. F. Mathew’s life-histories of 
for a considerable period, and wander to a great distance, 
for adult larve are found singly on bushes a long way 
apart. 
When full-grown the larva feeds perfectly exposed 
upon its food-plant, and is then a conspicuous object. 
It is from 52 to 55 mm. long, cylindrical, and tapers 
slightly towards the head, which is cordate, and notched 
on the crown, with a stiff branched spine springing from 
each lobe; cheeks, lower part of face and mouth, deep 
metallic blue, almost black; the second and third seg- 
ments much narrower than the head; whole of the 
dorsal and subdorsal area, as far as spiracular stripe, 
bluish or purplish, sometimes inclining to deep madder, 
and irrorated more or less with inconspicuous whitish 
dots; dorsal vessel interrupted, black; a subdorsal 
interrupted pale whitish stripe; an interrupted white 
spiracular stripe ; ventral area, legs, and prolegs smoky 
ereenish yellow; from fourth to tenth segments inclu- 
sive five, upon second and third four, upon twelfth six, 
and upon thirteenth four rigid, branched, blue-black 
spines, spring from a circular metallic blue-green base ; 
from fifth to twelfth segments inclusive, interrupting the 
white subspiracular stripe, a conspicuous orange-red 
cushion seated on the lateral skinfold, and from which 
spring yellow branched spines tipped with black ; 
Spiracles minute and black. 
When full-grown the larva spins a pad of silk to the 
underside of a leaf, attaches itself thereto, and becomes 
a smooth chrysalis of a reddish buff colour; a curved 
black line runs from the tail along the inner margin of 
the wing-cases to the eye, which makes it appear some- 
what boat-shaped; spiracles, and some subspiracular 
dots black, with a few black dashes and striz upon the 
wing-cases and abdomen. 
These larvee were taken between the 26th and 29th 
August at Aneiteum. They were very sluggish in their 
habits and flaccid to the touch, and were considerably 
infested by a dipterous parasite, and I lost several that 
were so attacked. The affected larve, when full-grown, 
ceased feeding, and remained stationary for two or three 
days, when they lost the power of holding on by their 
legs and anal claspers, and these two extremities falling, 
they were left suspended by their prolegs only, in a 
doubled-up position. Upon examination they were
