THE CANADIAN ENTOMOLOGIST. 361 



fully chitinized) ; closely allied to septentrionis , but distinct in the 

 confused small punctures of the interspaces, and the more flattened 

 elytral declivity. 



The front is as in septentrionis; but more densely granulate 

 and hairy, with the postepistomal smooth space and median pit, 

 and finely carinate above. The pronotum is as in septentrionis, 

 but usually more densely punctured and more strongly granulate 

 behind on the sides; the median carina narrow, distinct behind. 

 The elytra are much as in septentrionis; but much more broadly 

 rounded behind and with the declivity very distinctly flattened 

 when viewed from above, though not so strongly as in confiisus 

 Swaine and betulcB Hopk.; with the striae only lightly and narrowly 

 impressed on the disc; the sutural stria? rather strongly impressed 

 on the basal third; the strial punctures small and moderately deep; 

 the interspaces wide and flat; the interstrial punctures smaller 

 than those of the striae and rather numerous, uniseriate on the 

 1st, 2nd and 4th' interspaces, on the 3rd and 5th and the outer 

 interspaces confused with usually smaller additional punctures; 

 the declivity shining, distinctly flattened with the first two striae 

 distinctly impressed, the 2nd interspace impressed at the tip, the 

 interspaces on the declivity uniseriately very finely and rather 

 closely granulate-punctate in both sexes. 



The male has the front very wide, nearly as hairy as in the 

 female, with the median area at the base of the epistoma widely 

 impressed and shining. 



Variations: The size is fairly constant, as represented in our 

 collection, the length varying from 4 mm. to 4.8 mm. The most 

 important variation is in the interstrial punctuation. The first, 

 second and fourth discal interstriae are usually uniseriately punc- 

 tured but often variably confused towards the base and declivity, 

 the other interspaces are usually decidedly confusedly punctured 

 from the base to the top of the declivity with punctures of large 

 and smaller size. 



It is apparently a good species, distinct from septentrionis by 

 its flattened declivity and confused interstrial punctures. 



It is very abundant on the coast of British Columbia in the 

 bark of Douglas fir, and probably occurs also in other conifers. 

 We have specimens from as far north as Inverness and Queen 

 Charlotte Islands.
