of two new Coleopterous Insects. 227 
(without including the large spines) 9§ lines ; the anterior and 
posterior margins are slightly waved, and the fore part is rather 
broader than the hinder; the lateral margins are each armed with 
three acutely angular projections, the points of these processes 
being directed outwards ; one is situated in front, one behind, and 
the third in the middle of the lateral margin ; of these the last- 
mentioned is the largest, and the posterior spine (which may be 
regarded as a produced hinder angle of the thorax) is the smallest ; 
the upper surface of the thorax is very delicately punctured, but 
to the naked eye appears smooth. The prosternum is greatly 
produced downwards on the hinder part, and the fore-legs are 
joined to this produced portion ; between the bases of these legs 
is a narrow process of the prosternum, which, as it were, folds 
over the coxae, its apex (which is obtuse) being directed back- 
wards and upwards. The mesosternum has an obtuse process in 
front, the point of which is inserted under the process of the 
prosternum just described. The elytra are broadest at the base, 
attenuated behind, and very slightly dilated in the middle ; the 
shoulders, or outer anterior angle, is slightly produced, they are 
covered with numerous minute, irregular rugae, and these for the 
most part have a longitudinal direction ; on each elytron are two, 
somewhat indistinct, elevated longitudinal striae. The antennae, 
if extended backwards, would reach rather beyond the middle of 
the elytra. The legs are moderately long and compressed ; and 
on the underside of each of the femora are two longitudinal rows 
of minute pointed tubercles ; on the four posterior femora, the 
space between these tubercles is concave, on the anterior femora 
it is flat. The tibiae are furnished both on the upper and under 
sides with thickly-set minute tubercles. The tarsi are rather 
broad, especially those of the anterior pair of legs. The scutel- 
lum is of moderate size, rounded behind, and pointed in front.

I now proceed to the second insect, — one whose place in the 
system I find it difficult to determine. Its somewhat broad form 
and short antennae led me at first to suppose it might be allied to 
some of those genera which in most classifications follow the 
Prionidce — Pcccilosoma, Megaderus, See . — in the structure of its
