interspaces strongly convex, rather strongly imiseriately asperate and setose; 

 the scales of the elytra small and rather elongate, much smaller towards the 

 base, not very evident except on the sides and declivity where they are dense, 

 and variegated with a few light coloured patches. 



It differs from grandis in the slightly stouter form, the punctuation of the 

 front, pronotum and elytra, the finer elytral scales and deeper and wider elytral 

 striae, which are also deeper, and coarser than in tsugce. 



I have seen a few specimens through the kindness of Prof. H. F. Wilson, 

 labelled, "Santiam, N.F., Ore.; 8-21-14; Abies nobilis; W. J. Chamberlain, 

 collector; Or. Ex. Sta., No. 1428." 



Pseudohylesinus grandis, n. sp. 



Description of female. An elongate-oval species, rather stout, 3-5 mm. 

 long, and 1 -8 mm. wide; clothed with scales and short hairs, the elytra varigated, 

 distinctly stouter than nebulosus Lee. 



The head has the front convex above, the transverse impression wide, 

 straight and strongly margined in front, with a narrow, acute, medium carina 

 extending to the level of the anterior angle of the eyes; the front, vertex, and 

 genae closely, roughly, not very coarsely punctured, more densely on the vertex, 

 more sparsely on the epistoma; the front clothed with numerous short, stout, 

 erect hairs ; the vertex and a band behind the eyes with tufted hairs, the latter more 

 strongly and densely; the lateral margins of the epistoma acute and over-hanging 

 the deep antennal scrobes; the antennal club with the basal segment slightly 

 longer than the outer two which are subequal; the eyes elongate, slightly wider 

 above. 



The pronotum is distinctly narrower than the elytra, one-fourth wider than 

 long, the sides moderately arcuate, and narrowed towards the front oh the hinder 

 two-thirds, then moderately constricted; the front margin strongly rounded; 

 the disc transversely impressed in front; densely rather roughly not coarsely 

 punctured; the punctures shallow and irregular in size; with a narrow, shining 

 median carina; densely clothed above with fringed scales interspersed sparsely 

 with short suberect hairs, the scales passing into plumose hairs at the front and 

 hind margins, and the scales light coloured except in a large irregular patch on 

 each side the median line behind, on which they assume the ground colour; the 

 scales very easily removed. 



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

 longer than wide; strongly rounded at the base, and margined with close, wide 

 crescentic serrations; the sides parallel to the middle then strongly narrowed 

 and narrowly rounded behmd; the striae narrow, faintly impressed on the disc, 

 more strongly on the sides; the strial punctures small, shallow; the interspaces 

 wide, faintly convex, more noticeably behind; the first and third more strongly 

 on the declivity and the ninth carinate about the sides of the declivity as usual; 

 closely, finely punctured, with a somewhat regular row of subacute lunular 

 asperites becoming more numerous and confused near the base, the asperity 

 overhanging a larger puncture bearing a rather long slender hair, the smaller 

 punctures bearing short, wide, fringed scales which give the colour to the elytra; 

 the ground colour a deep rich brown to nearly black; with the scales on sections 

 of each interspace grey to yellowish, each interspace variegated individually; 

 the light patches forming a wide V-shaped marking about the middle of the 

 elytra; the interstrial asperities larger and more acute on the sides of the declivity 

 the ninth interspace carinate and dentate behind about the declivital margin. 



The prosternum is short, the process acute, the forecoxae narrowly separated; 

 the venter closely punctured, clothed with small light palmate scales; the 

 metasternum and base of the abdomen moderately inflated. 



The male differs in the shape of the pronotum, which is very much wider 

 than long, strongly rounded on the sides behind, very strongly constricted in
