This, in form, size, and general appearance, resembles C. canaliculatus, but the mentum is of a different 
form, and on comparison many other differences may be seen. From C, Schawmit Lee. (Proc. Acad. Nat. Soe. 
vi. 231) it differs by the smaller size, less rounded sides, but more acute angles of the thorax, and by the 
posterior angles being separated by a small but deep oblique impression: near the margin of the elytra may be 
seen a few whitish transverse undulated lines. The head is covered with minute rugose punctures, the disc 
rather circular and flat. The punctures on the thorax and elytra are of nearly equal size and form, irregular, 
numerous, very rarely confluent, each with the centre slightly raised, and emitting a minute seta; the pygidium 
is covered with rather large round punctures, The body beneath is glossy, with much fewer and smaller 
punctures ; the abdomen on the under side has a scarcely visible depression in the middle of the second segment. 
Mr. I. K. Lord, who collected several specimens of this species, informs me that it was taken at Colville, 
and is found all along the course of the Columbia river, as well as in Vancouver’s Island. Its habit is to 
frequent the roots, and to hide in the fallen leaves of the wild sage bushes (Artemisia), that grow on the sandy 
plains of the Columbia. Mr. Higgins has recently received this species from Japan: an interesting fact in the 
geographical distribution of the group. 
Species 12 (98)—CREMASTOCHEILUS PILOSICOLLIS. 
‘Black opaque; head convex coarsely punctured, and clothed with long erect black hairs; thorax 
moderately convex, densely and coarsely punctured, and clothed with long black erect hairs; anterior margin 
truncate at middle, rather suddenly sinuate within the anterior angles, which are moderately prominent ; sides 
rounded and slightly sinuate near the hind angles, which are moderately prominent, acute, and limited within 
by a faint groove. Elytra slightly convex, parallel, surface with coarse deeply impressed punctures, and sparsely 
pilose. Last spiracles moderately prominent. Pygidium convex, with coarse foveew and long hairs. Body 
beneath coarsely punctured, and sparsely hairy ; mentum with an obtuse point behind. 
‘Length,’ 44 inch.=11 millim. 
‘This species greatly resembles Cr. angularis, but is more convex and clothed with much longer hairs. The 
main difference between the two species is in the form of the tarsi and tibia, of which mention has already been 
made. 
‘One specimen from North Western California, collected by Mr. Gabb.’

viso; 2c, mento oblique et e prosterno viso). Wariat (in Mus. Leconte) colore piceo rufo.’
