368 THE CANADIAN ENTOMOLOGIST. 



sides, subparallel for three-fourths the length, then strongly nar- 

 rowed and rather distinctly constricted; the front margin moder- 

 ately rounded; considerably narrower than the elytra; the punc- 

 tures rather small and close on the disc, dense and somewhat 

 rugose on the sides, smaller, closer and somewhat rugose in front; 

 the smooth median line slightly elevated throughout, slightly 

 widest at the middle; the pronotum not acutely margined on the 

 sides behind. 



The elytra are twice as wide as long; moderately wider than 

 the pronotum, 13 to 10.5; the base truncate, acute; the humeral 

 angles rounded; the sides subparallel for nearly three-fourths the 

 length, then strongly arcuately narrowed and semicircularly 

 rounded behind as viewed from above, with the side margin bisinu- 

 ate behind; very narrowly rounded at the apex; the striae very 

 narrow and but faintly impressed upon the disc and sides; dis- 

 tinctly impressed on the declivity; the strial punctures small, not 

 larger than those of the pronotum, closely placed, deep and bordered 

 with black, of about the same size throughout; the interspaces 

 flat upon the disc and sides, faintly convex behind on the disc and 

 upon the declivity; densely, and rather coarsely granulate upon 

 the disc, becoming finely asperate upon the declivity and confused 

 throughout; the sides of the declivity impressed before the tip; 

 the pubescence minute, reddish and moderately distinct upon the 

 declivity; the basal third of the first three discal interspaces with 

 the strial septa and interstrial transverse roughenings strongly 

 oblique. 



The venter has the last segment densely punctured, very 

 broadly rounded behind, and moderately convex throughout: the 

 prothorax below closely punctured and rugulose with the punctures 

 more distinct than usual. There appears to be no sexual difference 

 in the few specimens available ; probably only one sex is represented. 



This species is related to macer Lee, and differs in the distinctly 

 stouter form; shorter and stouter pronotum, rugose on the sides 

 and in front; and the striae much less distinctly impressed. 



Type number, 2310a. 



The type is from Golden, B. C; also taken in the Creighton 

 Valley, B. C, in bark of dying Douglas fir.
