COLEOPTEROUS INSECTS.

and there are two tubercles towards the middle, and 
two others, one on each side, near the margin. The 
elytra are of a dull greyish yellow thickly clouded 
with black, and marked with longitudinal lines or 
striae. The under parts of the body and legs are 
black, slightly tinged with a metallic lustre. The 
male has an elongate, slightly nutant, horn on the 
hinder part of the head ; the female has two ele- 
vated cross ridges, which are somewhat arched. The 
length of the insect is about three or three and a 
half lines. 
The next important genus that presents itself to 
our notice, was established by Mr Macleay in his 
valuable work on the lamellicorn Coleoptera, and is 
named 
PHANJEUS. 
It is distinguished from all the allied genera, ex- 
cept Onitis } by the structure of the antennae. These 
organs consist of nine joints, the three last forming 
a mass of which the basal joint (or the seventh of 
the whole) is excavated and receives the following 
one within it, which is partly concealed and nearly 
of the figure of a horse shoe ; the terminal one is 
small and in the form of a reversed cup. The ra- 
dical joint of the labial palpi is larger than the others, 
and dilated on its inner side. There is no apparent 
scutellum, but a small opening is perceptible at the 
base of the sutural line, indicating its place. The
