than the anterior ; this stripe is also dotted and streaked 
with white ; an oblique stripe of the same colour springs 
from the spiracular region of the eighth segment, and 
runs into the ninth segment, as far as the base of the 
subdorsal spine ; a triangular blotch of the same hue on 
the tenth segment ; these stripes, besides being dotted, 
are more more or less bordered with white; there are 
some conspicuous black dots upon the lower part of the 
thirteenth segment, and a smoky V-shaped mark upon 
the anal flap; there is a subdorsal row of blunt fleshy 
spines, orange, except upon the ninth, tenth, and eleventh 
segments, where they are black; upon third, fourth, and 
fifth segments there are additional spines below the sub- 
dorsal row, and some minute fleshy points near the 
dorsal line ; head smoky black, with a white V-shaped 
mark upon the face; legs smoky ; prolegs, subspiracular 
and ventral area, from seventh segment to anal claspers, 
glossy white. 
When irritated these larve have the power of emitting 
two long carmine-coloured nuchal tentacles from a trans- 
verse, valve-like aperture, situated upon the crown of the 
second segment, just behind the head, and while the ten- 
tacles are exposed a disagreable odour of rotten oranges 
is distinctly perceptible. The larvae feed only by day, 
remaining perfectly quiescent throughout the night. 
- When within a couple of days of being full-grown it 
loses its power of exhibiting the carmine tentacles, but 
if annoyed, sways itself from side to side with a tremu- 
lous motion. Upon becoming full-grown it ceases to 
feed, remains in one position for several hours, and 
voids the contents of its intestinal canal, the ‘“ frass”’ 
becoming more and more liquified, until the larva finally 
passes a few drops of a clear, greenish, oil-like fluid. 
Shortly after this it commences to wander about search- 
ing for a suitable place to fix itself for its next change, 
and when it has chosen a spot it again remains quiet 
for an hour or two, and then begins to spin silk up and 
down the branch it has selected, taking care to lay it on 
thickest at the point which is to receive the terminal 
hooks of the chrysalis. The last thing it does is to 
spin the thread which girts the chrysalis, and this 
appears to be composed of a stronger material than that 
which is used for covering the branch with, although it 
may poss:bly be several threads united (as I know is the
