granules on the suture and along the region of the third interspace; the whole 

 declivity smooth and brightly shining, with the punctures extremely minute, 

 hardly visible except towards the sides. The disc and the declivity are almost 

 glabrous, with only minute very sparse pubescence; the pubescence about the 

 lateral margins very short but distinct. The last sternite is rather deeply, 

 broadly emarginate. 



The male has the front flattened as before, but coarsely, fairly closely 

 punctured with a well-developed median carina, and the pubescence almost 

 invisible, the last ventral is emarginate as in the female. 



Described from Quebec Province, Tullochgoram; Picea canadensis. Other 

 localities: Ste. Anne de Bellevue, Que.; Truro, N.S. 



About fifty specimens were received from the bark of a section of a dead 

 white spruce trunk, collected by Mr. Johansen at "Camp creek," below Sandstone 

 rapids, Coppermine river, Northwest Territories, February 15, 1915, in associa- 

 tion with Polygraphus rufipennis Ky., page 



The Coppermine specimens are constantly somewhat larger than the 

 typical form and the elytral striae are usually more finely punctured, but they 

 are left for the present under nitidus Sw.
