near the lateral and basal margins, convex on the sides, the ninth strongly 

 convex. The declivity is very steep, the caudal margin broadly rounded, not 

 at all produced; the suture finely, feebly developed, faintly granulate; sulcate 

 and distinctly but not strongly retuse on each side; the sulcus impunctate except 

 at the apex, comprising the second interspace, slightly impressed, rather wide 

 but hardly widened behind, smooth and shining; the third interspace very 

 minutely uniseriately granulate on the convexity and* faintly convex below, 

 where it joins the convex ninth interspace; the narrowly curved elevation thus 

 produced forming the ventral margin of the lateral convexity; the strial rows 

 distinct on the declivity but the punctures very minute; the interstrial punctures 

 almost obsolete. The pubescence of the dorsal surface is minute, nearly obsolete. 

 The abdominal sternites subequal in length, the last broadly emarginate. I 

 have not yet isolated any secondary sexual characters. The front in some 

 individuals is much more coarsely punctured and is plainly somewhat flattened, 

 with the carnia nearly obsolete. 



The type is from Isle Perrot, Que., in twigs of living Pinus strobus; also 

 collected at Ste. Anne de Bellevue, Que., and Stony Creek, Ont. 



Pityophthorus intextus, n. sp. 



Description of male. The length is 1 8mm. ; the width slightly more 

 than one-third the length; the declivity sulcato-retuse, with long bristles, not 

 acuminate. 



The head has the front shining, coarsely punctured, a transverse impression 

 on the cephalic half bounded behind by a rough transverse carina; the longi- 

 tudinal median carina very faint ; with fine pubescence in front of the transverse 

 carina; the antennal club very wide with the sutures transverse, slightly arcuate. 



The pronotum is as long as wide, broadly rounded and margined behind; 

 the hind angles rounded; the sides arcuate on the hinder half, rather strongly 

 constricted in front of the middle and semicircularly rounded in front; the 

 cephalic margin very finely serrate, the serrations recurved; the cephalic half 

 finely concentrically asperate, the rows becoming irregular on the sides; behind 

 shining, sparsely punctured, the punctures rather coarse, hardly smaller on the 

 sides; with a smooth median space, wider behind and carinate towards the 

 summit. 



The elytra have the base truncate, narrower than the pronotum at the base, 

 but becoming of the same width towards the middle; the sides somewhat 

 arcuate, subparallel for two-thirds the length; broadly rounded behind as viewed 

 from above, with the suture raised above the outline at the middle; punctured 

 in fairly regular rows; the strise not impressed on the disc, except the sutural 

 stride, those near the sides irregularly impressed; the strial punctures coarse and 

 deep, so that the surface is strongly roughened; the interspaces with coarse, 

 deep, setigerous punctures, sparse and irregular on the disc, rather close and 

 uniseriate towards the declivity and near the side margin: the punctures 

 decidedly confused about the scutellum. The declivity is strongly sulcato-retuse, 

 with the apex moderately rounded on the ventral margin, not acuminate; the 

 sulcus deep, wide, smooth and shining, slightly wider behind; the suture feebly 

 developed, very finely uniseriately granulate and with a row of fine hairs; the 

 lateral convexities with the third interspaces there strongly, uniseriately, rather 

 sparsely granulate, each granule preceding a long stiff bristle-like hair, with a 

 few smaller granules and a few similar long hairs on the remaining interspaces 

 of the convexity, and more numerous long hairs about the margin. 



The female has the front coarsely punctured above and on a narrow 

 space in front of the eyes, with the lower half of the front covered by a sub- 

 circular patch, extremely finely, densely punctured and very densely clothed 

 with fine, short, erect, yellow hairs of equal length; the patch bounded in front
