56 THE CANADIAN ENTOMOLOGIST. 
received a specimen of that insect from Dr. Harris, in which its charac- 
ters were all preserved, I am induced to describe C. agreste as a distinct 
species. 
_ It differs from C. rusticwm in being smaller, of a darker brown, with- 
out a tint of red; and in having more gloss. The prothorax has three 
deep round impressions, while in the insect last named, the impressions 
are slight, and the two anterior ones oblong: the elevated lines of the 
elytra are more prominent and become visibly confluent towards the apex, 
where they form several reticulations’: the underside of the body is much 
more thickly covered with hairs, which are hoary instead of yellowish, 
those on the breast being longer than those on the abdomen. In other 
respcts these two insects resemble each other. [Included in the genus 
Criocephalus Muls. Taken throughout Ontario and at Lake Superior. | 
[171.] 226. CaLtipium striatum Linn.—Length of body 5% lines. 
A single specimen taken in Lat. 65°. ; 
Body linear, black, thickly punctured, underneath with a few hairs, 
glossy ; above without any hairs or gloss. Antenne a little longer than. 
the prothorax: prothorax suborbicular, covered thickly with minute 
granules, with an elevated tubercle in its disk: elytra most minutely and 
thickly granulated, with four longitudinal slight furrows occupying the half 
adjoining the suture, the alternate interstices being most elevated : tarsi 
rufo-piceous. [Synonymous with Asemum mestum Hald. Taken through- 
out Ontario. | 
227. CALLIDIUM COLLARE A7zrby.—Length of body 5 lines. A single 
specimen taken in Lat. 54°. 
Body linear, black, hairy with whitish scattered hairs. Head thickly 
punctured ; antennæ shorter than the body, rather hairy, piceous, scape 
black: prothorax rufous, with a few scattered punctures, glossy, project- 
ing on each side into an angle or short spine: elytra very thickly and con- 
fluently punctured: body underneath glossy, slightly punctured: anterior 
part of antepectus rufous: tarsi piceous, first joint of nearly equal length 
in all the legs. [North Shore of Lake Superior, Agassiz’s Expedition. ]

of body 5—8¥ lines. Taken abundantly especially in Lat. 65° 
Body black, minutely punctured, hairy with longish hoary hairs, especi- 
ally underneath. Nose with a deeply ploughed transverse furrow ; front
