Elytra scarcely wider than pronctum, about 1.28 times as long as 
wide; sides subparallel on anterior two-thirds, broadly rounded be- 
hind; surface reddish to piceous brown, moderately shining; striae 
narrow, moderately deeply impressed, strial punctures rather small, 
longer than wide, not closely spaced ; interspaces wide, convex, densely, 
finely punctate-granulate; hairs numerous, very short and fine, very 
inconspicuous. Declivity (pl. 40, fig. 17) moderately steep; first inter- 
space slightly convex, finely, deeply, closely punctured, devoid of ser- 
rations except a few minute ones at summit of declivity; second 
interspace scarcely convex, finely and closely punctured, without ser- 
rations, only slightly narrower than others; third interspace very 
strongly elevated, with coarse, closely placed, black, blunt serrations; 
fifth to ninth interspaces each with a few serrations, rather coarse 
and four to six in number on fifth and seventh, smaller and less 
numerous on others; first and second interspaces clothed with moder- 
ately abundant scalelike hairs, the others with less abundant scales. 
Mesosternum nearly flat, with anterior portion slightly oblique. 
Female.—Similar to male in general habitus, frons wider between 
eyes than in male, frontal rectangle about 0.61 as long as wide, convex, 
densely granulate-punctate at sides and on lower half, more coarsely 
punctate and scarcely granulate above, with a distinct, arcuate, trans- 
verse impression between eyes; median carina fine, sharply elevated, 
on lower half; elytral declivity (pl. 40, fig. 16) with first interspace 
slightly convex, with small, sometimes obsolescent serrations, closely 
punctured and clothed with numerous scales; second interspace nearly 
flat, closely punctured and clothed with scales; third interspace with 
a row of moderately coarse, black serrations, with spaces between cov- 
ered with scales; with smaller serrations on the more lateral interspaces. 
The type of Phloeosinus cristatus (eConte) is in the Ulke collection 
at the Carnegie Museum, Pittsburgh, Pa., and I have not seen it. 
About a hundred specimens have been studied from Cupressus sp. or 
C. macrocarpa Gordon taken at Placerville, Oroville, Reedley, Fresno, 
Sonora, Walnut Creek, and North Hollywood, Calif., and from C. 
glabra Sudworth, or “arborvitae,” and introduced varieties of Cup- 
ressus in the Gila Valley of Arizona. 
PHLOEOSINUS CHIRICAHUA, new species 
Male.—Black with elytra dark reddish brown to piceous; 2.77 to 
8.5 mm. long, holotype 3.0 mm. long, 1.93 times as long as wide; 
closely allied to eristatus (eConte). 
Frons very wide between eyes, frontal rectangle about 0.61 as long 
as wide, epistomal lobe very short; surface shining, densely, moder- 
ately finely granulate-punctate at sides and below, more coarsely and
