Description. 
I add the following to supplement the description of the 
various stages of this insect given on pp. 68-69 of Jnjurious 
Insects. 
Larva.—The larva when quite small is elongate, never 
curved, white in colour with soft yellowish head and mandibles 
and twelve segments of nearly equal size. As it increases in size 
the head becomes yellowish brown, the: mandibles large, 
powerful and black, and the body-segments roundish, wrinkled 
and thick, the hind ones tapering slightly, the prothoracic one 
being the largest and hardest. Length 2} to 3 inches. _

beetle ; the elytra, however, are soft, white and curled down on 
to the breast, the antennz are held pressed over the back and 
the legs are pressed against the sides. The eyes are large, 
prominent and black, the tips of the mandibles also black and 
the jointed palpi prominent. Length 14 inch. 
_ Cocoon.—The pupa lies free in a curious, calcareous whitish 
cocoon, which to some extent resembles a pigeon’s egg. These 
cocoons are to be found lying at the ends of the larval tunnels 
in the wood of infested trees, 
The deetle is chestnut-brown in colour above and lighter- 
coloured below, the legs and antenna being of the same colour 
as the upper surface ; the head, upper and lower edges of thorax 
and outer and inner edges of elytra black. The head slopes for-

off from the inner angle of the eye; the first joint of the
