188 THE CANADIAN ENTOMOLOGIST 



not densely, confusedly punctured, with numerous minute hairs, 

 thicker and longer near the margin and on the strongh' raised 

 suture; the declivital armiture nearly as in grandicollis EichhofT; 

 the first tooth small, acute, on the end of the second intci space; 

 the second, on the fourth interspace, large, acute, the apex directed 

 dorso-mesad with the caudal margin crenulate and nearly \ertical, 

 connected at its base with the third tooth, which is stouter and 

 longer, blunt and somewhat curved meso-caudad; the fourth and 

 fifth teeth smaller and acute, on the decli\ital margin between 

 the 3rd and the acute apical margin, which is narrow^ acute, and 

 raised almost to the level of the tips of the 4th and 5th teeth. 



The female is somewhat less coarsely sculptured on the front 

 and declivity. 



There is considerable variation in the punctuation, and the 

 discal stiia" of the elytra are frequently decidedly impressed, 

 with all the discal interspaces convex. The length \aries from 

 4 mm., to 5.2 mm. 



This species is distinct from 'grandicollis Eich. in the larger 

 size, stouter form, shorter pronotum, and confusedly punctured 

 interspaces near the declivity; from vancomeri and confusus by 

 the very sparse punctures on the basal half of the discal inter- 

 spaces. 



The species is abundant in Ontario and Quebec Provinces, 

 chiefly in Picea canadensis and Pinus strohus; it extends south- 

 wards into New York State. The type is from Montreal Island, 

 P. Q., collected by Mr. G. Chagnon, of Montreal, and is deposited 

 in the collection of the Entomological Branch, Ottawa. 



Ips vancouveri, n. sp. 



Description of the male — Allied to confusus Lee, but stouter, 

 densely hairy, and much more coarsely suclptured; length, 5 5 mm.; 

 colour, dark reddish brown. 



The head has the front evenly convex, coarsely rather sparsely 

 granulate, more finely and densely on the sides; the cpistoma 

 transversely impressed, with a narrow median emargination; with 

 a compressed, short, blunt median tubercle at the base of the 

 epistoma, followed by a small median impression, and the smooth 

 median line obsolete; the vertex shining and nearly smooth; the
