Pronotum about 1.22 times as wide as long, widest near middle; pos- 
terior angles rounded; sides nearly straight and feebly divergent on 
posterior third, strongly, arcuately narrowed on middle third, con- 
stricted just behind broadly rounded anterior margin; surface piceous 
to black, rather feebly shining, impressed across dorsum back of anter- 
ior margin, finely, closely punctured and finely granulate on disk and 
sides; median line elevated on posterior half but punctured as on rest | 
of disk; with a small callus at each side; vestiture of fine, moderately 
short hairs, distinctly coarser and longer at sides. | 
Elytra wider than pronotum, about 1.8 times as long as wide; sides 
nearly straight and subparallel, moderately rounded behind; surface 
rather feebly shining; striae rather narrow, strongly impressed, with 
strial punctures small and rather inconspicuous; interspaces very wide, 
second widened at base, all moderately convex, densely granulate- 
punctate, with rather numerous larger asperities, usually confusedly 
arranged, but showing some tendency to a uniseriate arrangement near 
declivity ; vestiture rather abundant, of short, slender hairs, becoming 
stouter posteriorly on disk and sides. Declivity with all interspaces 
convex and rather sparsely subequally asperate, first and third inter- 
spaces slightly more convex than second, but with asperities about 
equal in number and size on all; vestiture consisting of a few fine, erect 
hairs arising from bases of asperities, and of more numerous stouter 
and shorter hairs, many of them scalelike, from surface of interspaces. 
Mesosternum precipitous and protuberant in front between coaxae. 
Female.—Similar to male in habitus, but wider between eyes, frontal 
rectangle about 0.9 as long as wide, densely coarsely granulate-punc- 
tate, median carina faint, often lacking except for a small epistomal 
tubercle; elytral declivity similar to that of male, but with more 
numerous scalelike hairs. 
Type locality —Riding Mountains, Manitoba, Canada. 
Host.—Pinus banksiana Lambert. 
Location of type.—Canadian National Collection. 
I have studied a series of 15 specimens collected and reared from the 
top of a small white pine by W. F. Fiske, on Grand Island, Mich., and 
recorded under Hopkins, U. 8S. Nos. 3775 and 3775a. 
PHLOEOSINUS PICEAE Swaine 
Phloeosinus piceae SwAINE, Can. Ent., vol. 66, p. 205, 1984—W. J. CHAMBERLIN,

“Length 2.2 mm.; width 1.3 mm. Black with short erect reddish 
pubescence, antennae and tarsi reddish; closely allied to pine Sw. 
“Head: In the female the front is subplanate with a feeble arcuate 
transverse impression, closely rather coarsely granulate, punctation 
indistinct, pubescence very fine, with a very fine median carina on
