sutures of the antennal club \ery strongly angulate at the middle; 

 the pubescence of the front close, long and erect. 



The pronotum is distinctly longer than wide, widest at the 

 base, with the sides slightly arcuately narrowed for two-thirds 

 the length, then strongh- narrowed to the narrow but broadly 

 rounded front margin; subconcentrically, not \ery densely asperate 

 in front; the pubescence abundant and long about the sides and 

 in front; closely, rather coarsel\- and deeph- punctured behind, 

 more closeh^ on the sides. 



The elytra are as wide as the pronotum, with the stride strongly 

 impressed on the disc, distinctly impressed on the sides; the sutural 

 stria^ deep and Avide, deepened towards the base, and widened 

 behind; the strial punctures coarse, close, deep and quadrate, 

 smaller near the declivity, the discal interspaces strongly convex 

 and coarsely roughly punctured, not closely near the base, densely 

 and confused on more than the caudal half, and granulate about 

 the declivity; the lateral interspaces with the punctures less coarse 

 but very densely confused throughout; the first interspace closely 

 confusedly punctured and uniseriately granulate; the second 

 interspace the widest, sparsely punctured in front, closely, con- 

 fusedly granulate-punctate on more than the caudal half and with 

 a row of acute granules terminating in the first declivital tooth, 

 ivhich is much closer to the second tooth than to the suture; the de- 

 clivital teeth otherwise nearh- as in confusus, but distinctly coarser, 

 the 2nd tooth conical acute, with its caudal margin sinuate and 

 nearly vertical, close to the 3rd, which is stout, subcapitate and 

 curved downwards, the 4th and 5th conical, on the margin of the 

 declivity between the 3rd and the narrow, strongly produced 

 apical margin; the concavit>' denseh'. deeply, rather finely punc- 

 tured, and densely clothed throughout with long slender pale 

 hairs; the elytra densely clothed with long hairs, more sparsely 

 on the disc. 



The female has the frontal tubercle of the male represented 

 by a slight median episternal carina, followed by a median shining 

 impressed area, and the declivital teeth less strongly developed. 



The species occurs in Sitka spruce and western white pine 

 on Vancouver Island and the coast of British Columbia; it occurs
