PHORODESMA BAJULARIA. 57 
Body flattened, attenuated towards the head, which 
is of the same colour as the body, reddish-brown. 
Dorsal line and wavy subdorsal line fuscous, a row 
of dark fuscous spots underneath the spiracles. On 
each segment from the fifth to the ninth (both in- 
clusive) is a pair of dark brown papille, one outside 
each subdorsal line, with a dark spot on the apex, 
furnished with a single hooked bristle (easily seen 
through a good glass), and also a pair on the twelfth 
segment, to which the gnawings are attached with 
silk. Being very curious to know how this was done, 
I put the half undressed individual just described into 
a box covered with glass, together with an oak bud 
just bursting into leaf. After surveying his new 
abode, previous to eating, he firmly fixed himself by 
his claspers (anal prolegs) to the bottom of the bud, 
took hold of one of the brown scales encasing the bud 
by the top with his jaws, and drew it with some force 
towards him, with the intention of pulling it off if 
loose (as some which he afterwards tried were); but 
as it was still firmly fixed at its base, after two or 
three strong pulls he began to gnaw it off at the base ; 
having effected which, he took it between his legs, 
turned it invariably with the convex side towards him, 
which he overlaid with silk, and then, taking it in his 
jaws, turned back his head and fixed it by the convex 
side to one of the naked papille, not contented with 
hooking it on, but winding silk about it at the point 
of connection. After putting on two or three pieces, 
he refreshed himself by eating for a few minutes. 
‘I'he new piece was not always put on a vacant papilla, 
but sometimes fastened with silk to another piece on 
a papilla already covered. The larva, at this stage of 
its existence, used almost exclusively the brown scales 
of the buds, probably as being so easily detached, but 
did not seem to care whether they were long or short, 
rounded or pointed; consequently the tout ensemble 
had certainly a ragged and untidy appearance, com- 
pared with the neatly cut and symmetrically arranged
