REVISION OF THE GENUS PHLOEOSINUS—BLACKMAN 441 
two to seven coarse serrations only at summit of declivity, with apical 
three-fourths to four-fifths flat, shining, finely, rather roughly punc- 
tured; second interspace very narrow, flat, shining, with a few 
punctures; third interspace elevated, with closely placed, dark serra- 
tions nearly as coarse as in cupressi,; fifth, seventh, and ninth moder- 
ately convex, each with a few, more widely spaced serrations, smaller 
than in third interspaces; hairs more numerous than on disk, 
short, rather fine, more numerous on first and third interspaces. 
Mesosternum nearly flat with anterior portion slightly oblique. 
female.—Similar to male in habitus; frons wider between eyes than 
in male, frontal rectangle 0.69 as long as wide, convex, densely granu- 
late-punctate, with an elevated, sharp median carina on lower half; 
elytra with discal interspaces notably wider and strial punctures 
smaller than in male; declivity with first and third interspaces ele- 
vated and regularly serrate but less so than in cupressi, second inter- 
space nearly flat, devoid of serrations, only shehtly narrower than 
third; fifth, sixth, seventh, and ninth with a few serrations; all inter- 
spaces from first to fourth on each side with numerous fine punctures 
and densely clothed with short, broad, cinereous, scalelike hairs and 
a few slender setae. 
Type locality.—Santian National Forest, Oreg. 
Host.—Not recorded. 
Location of type.—Canadian National Collection.

Male—Piceous with elytra reddish brown to piceous; 2.06 to 3.6 
mm. long, about 2.06 times as long as wide. 
Frons very wide between eyes, frontal rectangle about 0.68 as long

finely granulate-punctate at sides, roughly punctate, scarcely granulate 
above in median fifth; central area between eyes broadly, moderately 
deeply concave, finely punctate-granulate throughout except in median 
line; median carina nearly entirely lacking, appearing only as an in-

inconspicuous, scarcely visible except in profile. Eye about 3.16 times
