between eyes, median carina represented by a small tubercle at episto- 
mal margin; elytral declivity similar to that of male but with smaller 
serrations on interspaces 1 and 3, second interspace not narrowed at 
apex, entirely without serrations, but rather closely, strongly punc- 
tured; vestiture more abundant than in male, with many hairs flat- 
tened and somewhat scalelike. 
This species is closely allied to canadensis but differs in that all 
sutures of the antennal club are oblique and the median line and lateral 
calli of the pronotum are more strongly developed. The female dif- 
fers from that of canadensis in having the second declivital interspace 
wide to the apex and in having more abundant, scalelike hairs on the 
declivity. 
Phioeosinus scopulorum Swaine was described from specimens taken 
from Juniperus scopulorum Sargent at Williams Lake, British Co- 
lumbia. 
Through the courtesy of W. J. Chamberlin, of Corvallis, Oreg., the 
writer has studied a female paratype in the preparation of the de- 
scription. Two additional specimens, a male and a female taken 
from J. scopulorum at Vantage Bridge, Wash., by J. A. Beal and F. P. 
Keen, were studied carefully and are the only other specimens seen.

ScHept, Anal. Escuela Nae. Ciene, Biol., voi. 1, p. 887, 1940. 
Male.—Black, the elytra reddish brown to piceous brown; 2.0 to 2.51 
mm. long, about 2.0 times as long as wide; allied to canadensis. 
Frons moderately wide between eyes, frontal rectangle about 0.78 
as long as wide, epistomal lobe short; surface black, shining, finely, 
closely granulate-punctate below and at sides, roughly punctured above 
in median area, broadly arcuately, transversely impressed, with an 
elevated median carina on lower half; hairs moderately short and 
fine. Eye three times as long as wide, more than half divided by a 
rather wide emargination. Antenna with club less than half as wide 
as long, all of sutures oblique. 
Pronotum about 1.22 times as wide as long, widest behind; sides 
straight and subparallel on posterior third, then strongly, arcuately 
narrowed to the lateral constriction just behind very broadly rounded 
front margin; surface black, broadly, transversely impressed on an- 
terior third; disk shining, smooth, with deep, close, moderate-sized 
punctures, finer and denser near anterior margin, closely, roughly, sub- 
eranulately punctured at sides; median line feebly elevated behind, 
punctured throughout; lateral calli lacking or nearly so; vestiture of 
short, fine hairs on disk, slightly longer in transverse impression, much 
longer on sides.
