and very small, the ninth rather larger, and the two last forming 
an ovate club. Prothorax finely punctured, a little longer than 
broad, sides rounded and strongly constricted behind; the base 
with an oblong fovea on each side, close to the angles, and con- 
nected by a transverse line, which is very deeply and broadly 
impressed in the centre; the basal margin with a faintly 
impressed line. Elytra broader than prothorax, finely and 
irregularly punctured; humeral prominences strongly marked ; 
sutural stria straight, effaced posteriorly. Length, 14 mm. 
Besides the difference in the number of the joints of the 
antenne, it may easily be distinguished from the two preceding 
species by its strongly constricted and proportionately longer 
prothorax, and by its having the lateral foveee almost contiguous 
to the margin, and the basal line strongly impressed in the 
centre. 
The only British specimen I have seen of this species, and 
from which I have taken the above description, is in the collection 
of Mr. Oliver E. Janson, who found it in July, 1869, crawling on 
a whitened wall, at the base of which was a quantity of decaying 
vegetable matter.

Or all the methods of collecting Coleoptera there is none 
perhaps that requires more labour than wood-collecting; at the 
same time there is none that better repays a collector, or pro- 
duces rarer species. Some beetles bore into the solid wood, and 
are therefore hard to obtain; but there are numbers that live 
between the bark and the wood, and these may be comparatively 
easily procured. ‘The use of the wood-boring beetles in Nature 
is obvious,—like the dung-beetles, they are scavengers; when a 
large tree falls in one of the virgin forests of the tropies, if it 
remained as it lay it would create a block in the vegetation 
around that would soon cause a vacant space, and in time the 
forests themselves would become nothing but a mass of prostrate
