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 PoUjgraphus 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.
