PHLOEOSINUS FULGENS Swaine 
PLATE 38, FiGuRE 8 
Phloeosinus fulgens Swatne, 1924, Can. Ent., vol. 56, p. 147, 1924.—W. J. CHam- 
BERLIN, Bark and timber beetles of North America, p. 178, 1939. 
Male.—Black throughout except antenna and tarsi, brightly shin- 
ing; 2.0 to 2.71 mm. long, about 2.07 times as long as wide. 
Frons moderately wide between eyes, frontal rectangle about 0.72 
as long as wide, epistomal lobe short; surface moderately shining, 
strongly granulate-punctate throughout, broadly, moderately shal- 
lowly concave, with little indication of a median carina except for a 
small tubercle just above epistomal margin; hairs short and fine. 
Kye about three times as long as wide, more than half divided by 
a moderately wide U-shaped emargination. Antenna with club 
about twice as long as wide, all sutures distinctly oblique. 
Pronotum about 1.09 times as wide as long, widest on posterior 
third, sides nearly straight and subparallel on posterior third, then 
strongly, arcuately narrowed, constricted just behind moderately 
broadly rounded front margin; surface shining, transversely im- 
pressed just behind anterior margin; with dense, deep, moderate- 
sized punctures, finer and even more dense near front margin, punc- 
tate-granulate at sides; median line indistinct, lateral calli usually 
lacking; hairs very short and fine. 
Elytra wider than pronotum, about 1.34 times as long as wide, 
widest across basal serrations; sides nearly straight and subparallel, 
broadly rounded behind; surface shining; striae on disk moderately 
narrow, strongly impressed, punctures of moderate size, shallow, 
longer than wide, distinct; striae slightly wider and punctures slightly 
larger on sides; interspaces wider than striae, weakly convex, very 
densely, confusedly, rather coarsely granulate-punctate, granules 
not becoming uniseriate on disk; appearing glabrous, but with minute, 
very inconspicuous hairs, to be seen only in profile. Declivity 
(pl. 38, fig. 8) brightly shining, striae deeply impressed and strial 
punctures distinct; first and third interspaces strongly convex, each 
with a few, rather small, indistinct granules, and fine, indistinct 
punctures; second interspace more weakly convex, as wide as others, 
brightly polished, devoid of serrations or granules, with a few, very 
fine, obsolescent punctures; hairs sparse and minute. Anterior coxae 
moderately widely separated, anterior face of mesosternum oblique. 
Female.—Similar to male, but with frons wider and shorter, 
frontal rectangle about 0.69 as long as wide, convex; arcuate, trans- 
verse impression variable but usually strong, median carina sharply 
elevated on lower half; elytral declivity similar to that of male, the 
hairs slightly larger and more numerous but still short and fine.
