NORTH AMERICAN COLEOPTERA. 303 



impression opposite the fourth stria, surface more distinctly punctate than the 

 head and more decidedly alutaceous. Elytra finely striate on the disc, more dis- 

 tinctly impressed at sides and apex, the tenth stria wanting, striae finely punctate 

 on the disc, more coarsely and closely at sides, intervals flat, alutaceous, not dis- 

 tinctly punctate. Body beneath opaque black, nietasternal area shining, punc- 

 tate. Prosternum distinctly carinate, mesosternal elevation very narrowly oval, 

 punctulate. Legs rufo-testaceous. Length .06 inch. ; 1.5 mm. 



This species resembles granarius in having the elytral strise entire, 

 but differs in its opaque surface and the presence of an apical pale 

 spot. In the last two characters it resembles tristis, which has very 

 fine strise, not distinct at apex. 



Specimens in my cabinet from Nevada have the striae of the disc 

 somewhat more distinct, and consequently more distinctly punctate 

 than those from Canada oi- others from Sweden, but I can find no 

 reason for separating them as a distinct species. 



Occurs in our fauna in Canada and New England States to Mary- 

 land, also in California and Nevada. It is widely spread in middle 

 and northern Europe, extending to Siberia. 



C!. tristis Illig. — Oval, convex, distinctly narrower behind, black, subopaque, 

 alutaceous ; elytra with an apical pale space. Antennse testaceous, with darker 

 club, palpi pale testaceous, the last joint piceous. Head shining, distinctly and 

 moderately closely punctate. Thorax piceous, shining; sides arcuately narrowed 

 from base to apex, basal marginal line and ante-basal impressions wanting; sur- 

 face relatively coarsely punctate, a little closer at middle than at the sides. 

 Elytra distinctly alutaceous and subopaque, the strife replaced by rows of fine 

 punctures not closely placed, which are almost entirely obliterated at the sides 

 and apex, intervals flat, obsoletely punctulate near the base only. Body beneath 

 opaque black ; metasternal area shining, sparsely punctate. Prosternum dis- 

 tinctly carinate, mesosternal elevation lanceolate, with a distinctly punctate 

 surface. Legs rufo-testaceous. Length .06 inch. ; 1.5 mm. 



The difference between this species and lugubrls have already been 

 referred to. In addition, it will be observed that the mesosternal 

 elevation presents a rather larger ai-ea than in either that species or 

 granarius. The pale space at the apex of the elytra is not strongly 

 defined and extends along the side nearly to base. The epipleurae 

 are pale in all three species. 



Specimens are known to me from Ohio and Michigan, westward to 

 Iowa, Dakota, California, Washington and Nevada. In the eastern 

 hemisphere it occurs from northern Europe to Siberia. 



C. liori«lamiS n. sp. — Oval, slightly more narrowed behind, convex, head 

 vertical, piceous black shining; elytra with a well defined apical pale space, 

 which extends narrowly along the side to the humerus. Antennse rufo-testace-
