Black, moderately shining. Rostrum flat above, without triangular im- 

 pression at tip, obtusely carinate at middle, a slight perforation between the 

 eyes, surface coarsely punctured, sparsely pubescent. Thorax slightly 

 broader than long, sides arcuate, apex truncate, base feebly arcuate, surface 

 densely tuberculate and sparsely pubescent. Elytra regularly oval, finely 

 striate, striae coarsely punctured, intervals flat, slightly wrinkled and with 

 patches of scale-like hairs irregularly interspersed. Body beneath and

Oblong oval, black, shining. Rostrum above flat, sparsely punctured, 

 median line smooth, a puncture l)etween the eyes. Thorax longer than 

 wide, widest in front of middle, sides moderately arcuate and very slightly 

 sinuate near the base ; surface shining, finely and rather sparsely punc- 

 tured. Elytra regularly oval, surface not striate, but with moderate punc- 

 tures in indistinct rows, intervals irregularly bi seriately punctulate. Body 

 beneath black, shining, more rugulose than above. Femora unarmed. 

 Length .26-. 28 inch ; 6.5-7 mm. 



The tip of the rostrum on each side of the emargination is slightly pro- 

 longed in an obtusely conical process. The same may be seen though to a 

 much less extent in the other species. This species is easily known by its 

 smooth shining surface and sparsely punctured thorax. 



Occurs in Greenland.

 cavernous and of oval form. Antennae long, scape passing the anterior 

 margin of the thorax, rather slender, gradually thicker toward tip and 

 rather strongly arcuate ; funicle 7-jointed, the first two joints moderately 

 long, joints 3-7 obconical gradually shorter ; club elongate oval. Eyes 

 oval, slightly longitudinal. Thorax cylindrical, sides slightly arcuate. 

 Elytra rather broadly oval, moderately inflated. Scutellum wanting. 

 Metasternum very short. Intercoxal process of abdomen short, broad, 

 truncate in front, second segment but little longer than the third separated 

 from the first by a nearly straight suture. Cotyloid cavities of hind tibiae
