PHLOEOSINUS PINI Swaine 
Phloeosinus pint SwAINE, Can. Ent., vol. 47, p. 362, 1915; Canada Dept. Agr., Ent., 
Branch, Bull. 14, pt. 2, pp. 67, 69, 1918.—W. J. CHAMBERLIN, Bark and timber 
beetles of North America, p. 175, 1939. 
Male—Piceous-brown to black, with elytra reddish brown to piceous- 
brown; 2.1-2.5 mm. long, about ® 1.92 times as long as wide. 
Frons moderately wide between eyes, frontal rectangle about equal 
in length and width; epistomal lobe longer than usual for genus, with 
free end emarginate; surface black, subopaque, densely granulate- 
punctate; central area with a moderately deep, subcircular concavity 
slightly less than half as wide as distance between eyes, with a fine, 
rather weakly elevated, often distinct, median carina on its lower 
half; hairs fine and moderately short, inconspicuous. Eye about three 
times as long as wide, more than half divided by an emargination. 
Antenna with club about 1.7 times as long as wide, first two sutures 
slightly oblique, partly septate; third rather strongly oblique. 
8 The use of the limiting term “about” in this and all other descriptions does not indicate 
that the measurements were guessed at or carelessly taken. The measurements and compu- 
tations were very carefully made and, it is believed, apply with exactness to the specimens 
measured. However, there is a small amount of individual variation, and for that reason 
the limiting term “about’’ was inserted.
