The elytra are slightly, distinctly wider than the pronotum, one-half longer 

 than wide, strongly arcuate individually at the base, acute and serrate; the 

 sides subparallel to the middle, then arcuately narrowed and narrowly rounded 

 ])ehind; the strise narrow, moderately impressed nearly to the base, more 

 strongly on the sides behind; outcurved at the base; the first stria and first 

 interspace rather strongly impressed behind the scutellum; the strial punctures 

 very small, deep and close, indistinct at the base; the interspaces wide, moder- 

 ately convex, more strongly behind; the first and third more stronglj^ elevated 

 on the declivity; the ninth carinate and more strongly asperate about the sides 

 of the declivity; the interspaces finely asperate, densely towards the base, 

 except the first, uniseriately behind; the pubescence of stout hairs at the base, 

 becoming short and scale-like on the declivity, with longer tufted hairs on the 

 sides; the second abdominal sternite nearly as long as the first and fifth. 



The type is from Stanley Park, Vancouver, B.C., in Tsuga heterophyUa; 

 widely distributed along the British Columbian coast. 



Pseudohylesinus sitchensis, n. sp. 



This species is barely distinct from grandis. The size and shape are 

 practically the same, slightly more slender; the front rather coarsely and 

 closely punctured, not so densely as in grandis; the transverse impression deeper 

 than usual. 



The pronotum is wider than long, 13:10; the sides strongly arcuate on the 

 caudal two-thirds, strongly constricted in front of the middle; broadly rounded 

 on the front margin; the median carina nearly obsolete; the punctuation small, 

 dense and finely granulate, with larger setose punctures intermixed, more 

 numerous on the sides; the pubescence on the disc of intermixed clavate setse 

 and very stout scale-like hairs, with greyish clavate setae and palmate or tufted 

 scales on the sides; sparsely, finely asperate on the sides. 



The elytra are one-half longer than wide, slightly narrower than in grandis; 

 the strige narrow, with small, close punctures, moderately impressed; the inter- 

 spaces wide, moderately convex, finely uniseriately asperate and setose as usual, 

 rather irregularly towards the base; the scales less dense than in grandis, and 

 elongate, becoming tufted behind the scutellum and notably so on the sides; 

 the marking of the grandis type, but more regular, an elongate whitish mark 

 behind the scutellum, followed by a dark and then by a light-coloured elongate 

 V-shaped marking, with the caudal third mottled in sections of the interspaces. 



This species appears to be distinct from grandis, particularly in the elongate 

 scales and the different shape of the pronotum. 



Our specimens are few in number; probably the species is rare. The type 

 is a male; the female has the pronotum less strongly constricted in front. 



Menzies Bay, B.C.; also Port Renfrew and Stanley Park, B.C. A rare 

 species, in Picea sitchensis. 



Pseudohylesinus nobilis, n. sp. 



Description of female. — Allied to grandis, but more coarsely punctured, 

 more deeply striate and somewhat stouter, with the scales almost obsolete 

 on the pronotum and small on the elytra; length, 3-9 mm.; width, 1-8 mm. 



The head has the front very coarsely, sparsely punctured on the disc, 

 moderately and more closely on the beak, finely and very densely on the vertex, 

 less roughened than usual; the antennal club as in grandis. 



The pronotum is rather stouter than in grandis, finely, very densely punctured 

 with larger punctures intermixed, and indistinctly asperate on the sides. 



The elytra have the general form of grandis; but with the striae deeper and 

 wider; the strial punctures rather coarse, slightly smaller on the sides, the
