PHLOEOSINUS NITIDUS Swaine 
Phloeosinus nitidus Swaine, Can. Ent., vol. 56, p. 145, 1924—W. J. CHAMBER- 
LIn, Bark and timber beetles of North America, p. 177, 19389. 
Male.—Piceous black, with elytra reddish brown; 2.5 to 3.4 mm. 
Jong, about 2.08 times as long as wide. Closely related to Phloeosinus 
cupressi Hopkins. 
Frons moderately wide between eyes, slightly narrower than in 
cupressi, frontal rectangle about 0.73 as long as wide, epistomal lobe 
short; surface piceous, finely, densely granulate-punctate at sides, 
more sparsely punctured, not granulate above in median fifth, entire 
median area brightly shining; moderately deeply, not broadly con- 
cave between eyes, concavity smooth and impunctate above, very finely 
subgranulate-punctate on epistoma, with a rather broad, blunt median 
carina on lower half; hairs short, fine, and inconspicuous. Eye about 
3.4 times as long as wide, more than half divided by a rather wide 
U-shaped emargination. Antenna with club less than twice as long 
as wide; first two sutures distinctly oblique, third suture more strongly 
oblique. 
Pronotum about 1.1 times as wide as long, widest at posterior angles; 
sides nearly regularly, convergently arcuate, only slightly constricted 
just back of the moderately broadly rounded front margin; surface 
piceous, shining; finely, rather closely, very deeply, somewhat roughly 
punctured on disk; very finely and densely punctured near anterior 
margin; sides subgranulately punctured; lateral calli small but dis- 
tinct; median line scarcely elevated on posterior fifth; surface indefi- 
nitely impressed at each side near posterior border; hairs fine and 
inconspicuous (much shorter than in cupressi), hairs just anterior to 
lateral calli notably longer. 
Elytra slightly wider than pronotum, about 1.28 times as long as 
wide, usually slightly wider at base; sides nearly straight (feebly 
sinuate) and subparallel on anterior two-thirds, very broadly rounded 
behind; surface shining, striae deeply impressed, more than half as 
wide as interspaces, strial punctures large, shallow, close; interspaces 
on disk rugose-granulate, with fine, sparse punctures, convex granules 
confused on anterior portion, tending to become uniseriate posteri- 
orly; on sides interspaces little wider than striae, nearly smooth, with 
granules and rugosities only on posterior portion; hairs short and 
fine, not abundant. Declivity similar to that of cupressi with de- 
clivital serrations coarse and dark; first interspace convex and with
