NATURAL HISTORY OF 
the base. The elytra are scarcely wider tnan the 
base of the thorax, deeply grooved near the suture, 
and marked with punctured lines on the sides, each 
of them with two narrow lines of reddish yellow. 
The anterior thighs are furnished with a small tooth 
on the under side. Like all the other species of the 
genus, this insect lives under bark, and is often found 
on the stems of old trees congregated in hundreds.

culio barbirostris, Fair . 
The species given as an example of this genus — 
which may be briefly characterised by the elongate 
shape of the terminal joint of the antennae, and the 
length of the fore legs — is found at the Cape of 
Good Hope. It is entirely of a black colour, ex- 
cept the hairs on the rostrum, which are reddish 
yellow. The rostrum or snout is longer than the 
thorax, trifid at the point, and tuberculated above. 
The thorax is rough with deeply impressed punc- 
tures, and bears yellowish hairs on the sides and 
beneath. The elytra are marked with closely placed 
lines of deep square punctures, the spaces between 
which have a few short hairs. The anterior legs 
are much longer than the others, and all the tibiae 
are armed with a few remote spines.
