interspaces each with a few smaller serrations and fine punctures; 
vestiture more abundant than on disk, consisting of a few slender 
setae from bases of serrations and much more numerous flattened 
scalelike hairs. Mesosternum with anterior face steep. 
Female.—Similar to male in habitus; frons wider between eyes 
than in male, frontal rectangle about 0.71 as long as wide, convex, 
finely, densely punctate-granulate, arcuately impressed, with a fine, 
distinct median carina; elytral declivity similar to that of male, but 
with serrations smaller and scales much more abundant. 
This species was described by Swaine from specimens taken from 
“cedar limbs” in California by R. Hopping. 
The specimens that I studied came from various localities in Cali- 
fornia, as follows: General Grant National Park, Sequoia National 
Park, Yosemite National Park, Giant Forest, Wawona, Bass Lake, 
Milford, Millwood, Pinecrest, Fallen Leaf Lake, Ellis Meadow, 
Miami, Mount St. Helena, and Monterey. The hosts cited include 
Libocedrus decurrens Torr., Juniperus occidentalis Hook., and 
Cupressus macrocarpa Gordon.

PLATE 38, FIGURE 2 
Male.—Black, with elytra piceous to reddish brown; 1.75-2.385 mm. 
long, holotype 2.10 mm. long, about 2.13 times as long as wide; 
closely allied to hoppingi Swaine. 
Frons wide between eyes, frontal rectangle about 0.79 as long as 
wide, epistomal lobe rather short; surface piceous black, moderately 
shining, finely, closely granulate-punctate at sides, punctured and 
subgranulate above; deeply and broadly concave, concavity extend- 
ing from level of top of eye to epistomal margin, finely punctured 
except at center, median carina lacking except for a small carinal 
tooth on epistomal margin; vestiture consisting of short, slender 
hairs. Eye three times as long as wide, about half divided by a 
moderately wide U-shaped emargination. Antenna with club about 
1.8 times as long as wide, first two sutures feebly oblique, third suture 
more strongly oblique. 
Pronotum about 1.20 times as wide as long, widest through pos- 
terior third; sides strongly arcuate on posterior two-thirds, con- 
stricted just behind broadly rounded front margin; surface shining, 
black with anterior margin piceous, transversely impressed across 
dorsum in anterior fourth; disk with very deep, rather close, mod- 
erately large punctures (slightly larger and closer than in 
hoppingi), interstices not granulate, closer and slightly finer near 
anterior margin, sides with punctures larger, close, subgranulate; 
median line feebly elevated on posterior fourth only; lateral calli
