and distinctly scalelike while in seguotae it is much scantier and 
for the most part hairlike. Swaine, in Canadian barkbeetles, page 70, 
does not distinguish this species from sequoiae, for in referring to 
seguoiae he considers it as “probably the common larger Phloeosiivus 
of British Columbia cedar.” This is really squamosus.

Male.—Piceous to black, with elytra reddish brown; 2.1 to 3.0 mm. 
long, about 2.0 times as long as wide; allied to dentatus (Say). 
Frons moderately wide between eyes, frontal rectangle about 0.76 
as long as wide, epistomal lobe short; surface piceous, densely, rather 
finely punctate-granulate at sides, middle third punctate, scarcely 
granulate above, shining and nearly impunctate below, moderately 
deeply, widely, transversely impressed in an arcuate area between 
eyes; median carina bisecting impression, usually moderately de- 
veloped; hairs short and fine, inconspicuous except in profile. Eye 
sightly more than three times as long as wide, more than half 
divided by a V-shaped emargination. Antenna with club 1.9 times 
as long as wide, sutures sinuate, first two distinctly oblique, third 
strongly oblique. 
Pronotum about 1.18 times as wide as long, widest near base; 
sides arcuate and converging on posterior two-thirds, strongly con- 
stricted in anterior third, broadly rounded in front, weakly im- 
pressed across dorsum in front; surface moderately shining, punc- 
tures moderately small, close, and very deep on disk (somewhat 
coarser and closer than in dentatus Say), finer and denser in front, 
roughened, subgranulate at sides; median line evident on pos- 
terior third, with surface indefinitely impressed at each side;
