likely that the shore pine species is the true sericeus of Mannerheim. I have one 

 specimen of grandis taken from the surface of the bark of a Sitka spruce, and one 

 specimen from Queen Charlotte Islands where neither Douglas fir nor grand fir 

 have been found, nor, so far as we know, any other species of Abies. 



I have never taken any species of this genius from shore pine and am assuming 

 that Hopkin's species is the same as Leconte's first specimen, which, if from a tree 

 indigenous to the Alaskan coast, should be accepted as fixing the species. 



Pseudohylesinus obesus, n. sp. 



A stout species, gradually wider behind, the pubescence scale-like only on 

 the declivity; length 4-5 mm,; width, 2 mm. 



The head has the front shining, punctuation moderately close, not coarse; 

 the transverse impression deep, but narrow; the carina strong and acute; the 

 beak twice as wide as long, deeply impressed on each side of the carina in front; 

 the median lobe very large, excavated above as usual; clothed with short 

 slender reclining hairs. 



The pronotum is slightly wider than long, 17:14; the hind margin strongly 

 bisinuate; the sides subparallel, slightly convergent for over half the length, 

 then suddenly, strongly constricted, broadly rounded on the front margin; 

 the punctuation dense, shallow, smaller and large intermixed, somewhat granu- 

 late, sparsely asperate on the sides; the pubescence rather abundant, short, 

 slender, and reclining, somewhat tufted in front of the scutellum. 



The elytra are one-half longer than wide; strongly rounded and finely 

 crenulate at the base, more distinctly towards the sides; somewhat dilated 

 behind, widest behind the middle; rather narrowly rounded behind; the striae 

 very narrow and faintly impressed on the disc, distinctly impressed on the 

 sides, the strial punctures rather small, and very closely placed; the interspaces 

 very wide, faintly convex, the ninth carinate about the declivity as usual, and 

 the first and third distinctly convex near the tip, minutely, not roughly punc- 

 tured, rather finely asperate, uniseriately except near the base, and on the basal 

 half of the third and fifth; the pubescence very short and rather dense, in the 

 form of stout hairs on the disc, tufted on the sides, and elongate scales on the 

 declivity; the hairs from the asperate punctures present but very short and 

 indistinct. 



The type is from Inverness, B.C. It is apparently a rare species. 



Leperisinus cinereus, n. sp. 



This species is very closely allied to aculeatus, Say, but somewhat stouter 

 with the elytra more convex at the middle; the pronotum with elongate, trans- 

 verse asperities arranged much as in aculeatus, with the pronotal surface less 

 strongly rugose; the elytral stria3 wider and distinct, the interstrial asperities 

 much smaller than usually found in aculeatus, hardly distinct even on the 

 declivity; the vestiture of scales as in aculeatus, but the colour everywhere very 

 pale, cinerous, with the red surface showing at the margin of the pronotum and 

 about the bases of the elytra; very indistinctly marked with yellowish brown on 

 the usual diamond-shaped median stripe, and the irregular lateral stripe of 

 each side on the pronotum, with very indistinct traces of the same colour on 

 the elytra. In some specimens the colour is more distinct, and there is a 

 tendency towards two angulated transverse lines on the elytra. 



The species was found first among material of aculeatus taken from ash at 

 Hudson, Que. It is also represented from Cambridge, Roxbury, and Brookline, 

 Mass.
