thorax, are always much broader than the others. Cameron 
writes to me that this is more especially the case in young 
examples; but this is contrary to my observation, which was, 
however, confined to a single young specimen. In the paler- 
coloured larve traces of a green dorsal vessel can be perceived 
through the skin. I conclude that the deep yellow larve are 
somewhat older than the paler individuals. The sutures of the 
head are marked out with brown; the jaws and the antenne are 
also generally pale brown (figs. 3 and 4). The thoracic legs are 
blunt, conical processes, and consist of two joints, the latter 
of which is very small and nipple-shaped, and without any trace 
of a claw (fig. 5); the middle legs are thick and very blunt 
(fig. 6), and the last pair is reduced to an oval blunt, wart-like 
prominence, having two brown oblong spots underneath (fig. 7). 
I was not able to count the middle legs. 
Before changing to a pupa the larva lies in the cocoon in a 
curved position, like the larve of the weevils, as represented at 
fig. 8 (the head is shown at fig. 9). It may here be remarked that 
figs. 8 and 9 were drawn at the end of March, and fig. 4 in the 
autumn; this may in some measure account for the difference 
in colour. Iam unable to say positively when fig. 8 was drawn, 
but I think in September. 
The pupa (fig. 10) shows very clearly the different divisions of 
the body, and gradually assumes the colouring of the perfect 
insect. 
Fig. 11 represents the imago, a female; it is small and 
rather broad. The head is unusually broad, and connected to the 
prothorax by a narrow neck; the eyes are very projecting. The 
general tint of the body is a somewhat metallic-black. The head - 
has two broad lines along the inner margin of the eyes, a spot 
between the antennz in the form of a horseshoe, the clypeus, 
the upper lip, the mandibles, the cheeks, and the palpi, white or 
yellowish white. The antenne, consisting of ten joints (see fig. 12), 
are brown, and are somewhat thickened towards the apex; the 
first two joints are black bordered with white. The posterior 
margin of the prothorax and the tegule are yellowish white ; 
the cenchri are greyish brown. The opening in the dorsum 
between the first and second segments of the abdomen is rather 
large, and on the bordered margin of each segment is a bluish 
white oval spot (fig. 13). The sheaths of the ovipositor are shining
