Elytra distinctly wider than pronotum, about 1.82 times as long as 
wide, widest behind middle; sides feebly arcuate, subparallel, semi- 
circularly rounded behind; surface reddish brown, shining; striae 
moderately wide and distinctly impressed on disk, with punctures 
moderately small and close (striae distinctly wider and punctures 
coarser than in dentatus), striae notably wider and punctures coarser 
on sides; interspaces about twice as wide as striae, feebly convex on 
disk, densely granulate-punctate, with many fine and fewer coarse 
granules, confused on most of disk, but coarser granules becoming 
uniseriate toward declivity, interspaces narrower on sides, with gran- 
ules less numerous; hairs short, fine, inconspicuous (much less num- 
erous and smaller than in dentatus). Declivity with first and third 
interspaces elevated; the first with numerous large, dark, sharp ser- 
rations, some obsolescent, others obsolete, finely and closely punc- 
tured; third interspace with more numerous, somewhat smaller serra- 
tions, with fewer punctures; second interspace shining, nearly fiat, 
about as wide as first, wider than third, finely, moderately sparsely 
punctured, with only one or two small serrations near apex; fifth and 
seventh interspaces convex, each with four or five small serrations and 
only a few punctures; all declivital interspaces with moderately sparse, 
short, yellowish hairs, some of them scalelike. Anterior face of 
mesosternum short, moderately oblique. 
Female.—Similar to male in habitus; frons very wide between eyes, 
frontal rectangle about 0.68 as long as wide, convex, with wide, 
shallow postepistomal impression, densely, coarsely granulate- 
punctate, median carina obsolescent; elytral declivity with serrations 
similar in arrangement to those of male, but much smaller, second 
interspace often with several small serrations, sometimes with only 
one at apex, punctures close and fine throughout; entire declivity 
rather densely clothed with numerous, yellowish, flattened, scalelike 
hairs, with a few fine, rather short, erect setae from bases of serrations. 
Phlocosinus juniperi was described from specimens taken by Hop- 
ping, Scaffold Meadow, Tulare County, Calif. No host was men- 
tioned. The writer has studied more than 90 specimens, including 
4 from the type locality collected by Hopping and J. M. Miller. 
Other specimens were taken at Yosemite National Park and Willow 
Ranch, Calif.; Prineville, Beatty, Klamath Fails, and Redmond, 
reg.; and Northport, Wash. The hosts cited are Juniperus occi- 
dentalis Hook. or Juniperus sp.
