" Very abundant at the mouth of the Pic river, on the north 

 side of Lake Superior, under dried animal matter. This species 

 is broader and less convex than C. consobrinus, and is easily 

 known by the more distinct punctuation, and by the absence of 

 the transverse lines. The thorax is densely and finely punctulate ; 

 it is about twice as wide as its length, strongly narrowed in 

 front, rounded on the sides, especially anteriorly, slightly emar- 

 ginate at apex, truncate at base, and very slightly sinuate at the 

 posterior angles, which are scarcely perceptibly acute. The 

 anterior tarsi of the male > and the first joint of the middle tarsi, 

 are dilated *. ;>

Oblong-oval, nearly of the same size and form as C. alpinus, 

 brown, a little darker behind and on the middle of the thorax. 

 The antennae are longer than the head and thorax; the basal 

 joints (first, second, third, fourth and fifth) and the last joint are 

 ferruginous-yellow ; the seventh, eighth, ninth and tenth joints 

 blackish-brown ; first joint large, and longer than second ; second 

 thin and slender, a little longer than third ; third, fourth and fifth 

 thin and slender and very short, nearly all of equal length ; sixth 

 shorter than these, but rather broader ; seventh largest and 

 broadest of the whole ; eighth excessively minute ; ninth and 

 tenth of equal length and thickness, rather narrower than the 

 seventh, their sides more parallel than is the case in other spe- 

 cies; eleventh of the same breadth as the two preceding. Head
