new Spectes of Histeride. 421 
Cylindrical, subelongate, truncate, brown and shining ; the 
head, surface with shallow punctures not densely set, but 
intermixed with fine points, forehead concave, with a strong 
lateral stria angulate in the middle, at the angle the canthus 
of the eye projects; the thorax is punctured somewhat simi- 
larly to that of the head, the marginal stria is very fine and 
continued along the base, at each of the anterior angles there 
is a well-marked inner stria and behind the head there is 
another detached stria which is somewhat crenulate and bent 
backwards at either end; the elytra, strie, inner humeral 
fine and complete, first dorsal is basal and anteriorly bent, 
second is straighter and a little longer, the sutural commences 
just behind the middle of the dorsum and continues along the 
base, and then turning backwards apparently represents a 
short third dorsal stria, the surface is sparingly punctulate 
posteriorly ; the pygidia are more distinctly punctured ; the 
prosternum, keel narrow and striate between the coxe; the 
mesosternum is markedly marginate, wider than long, and 
sinuous anteriorly ; the legs, anterior tibize are strongly angu- 
late at the base on the inner edge, and there is a groove and 
an overlapping edge in the femur to receive the projection 
on the outer edge, the tibize are 4-dentate, apical tooth being 
very robust, intermediate tibie 3—4-spinose, posterior without 
Spines except two at the tarsal end.

ad 
I have lately obtained Marseul’s type of Macrosternus 
Alluandi, and find it is identical with Pachycrerus latus, Lew. 
There is no doubt of its being a Pachycrerus, but Marseul’s 
specific name has priority to mine. 
Pachycrerus assinius. 
Macrosternus assinius, Mars. Bull. Soc. Ent. Fr. (6) viii. p. ix (1888). 
I have also acquired the type of this species; the thoracic 
fossettes are similar to those of Pachycrerus, and so are the 
general characters of the species, except that the anterior 
outline of the mesosternum “is nearly straight in front,’ as 
Marseul says, but I think this is only so on the surface. 
There is only one species at present properly placed in
