lateral calli lacking; hairs cinereous, rather short, inconspicuous on 
disk, notably longer and more conspicuous on sides. 
Elytra slightly wider than pronotum, about 1.19 times as long as 
wide; sides nearly straight and subparallel on anterior two-thirds, 
broadly rounded behind; surface shining; striae moderately narrow, 
deeply impressed, punctures rather small, rather deep, moderately 
close; interspaces much wider than striae, not uniform in width, first 
much wider behind, finely granulate-punctate, with larger asperities 
confused near base, becoming uniseriate farther back on disk and 
sides; vestiture of moderately abundant, short, fine hairs on anterior 
part, becoming stouter and more conspicuous behind. Declivity (pl. 
88, figs. 3, 3a) with first and third interspaces moderately strongly 
convex, each with a row of rather sparse, moderately large, sharp, 
recurved serrations, and with numerous small, close, deep punctures; 
second interspace nearly flat, shining, narrowed posteriorly, with fine, 
rather rough punctures; fifth, seventh, and ninth interspaces each 
with a few small serrations and small punctures; vestiture consisting 
of a few slender setae from bases of serrations and many stout, flat- 
tened or scalelike hairs. Anterior face of mesosternum somewhat 
obliquely declivitous. 
Female.—Similar to male in habitus, frons wider between eyes, 
frontal rectangle about 0.7 as long as wide; finely granulate-punctate 
at sides, punctured above, broadly transversely impressed, with a dis- 
tinct elevated median carina, vestiture of moderately short, slender 
hairs‘; elytral declivity similar to that of the male in general fea- 
tures, but with serrations notably smaller, punctures denser, and 
vestiture much more abundant. 
Type locality —Rialto, Calif. 
Host.—Cupressus arizonica Greene. 
Type material—Holotype and allotype, U.S.N.M. No. 58820. 
Remarks—The foregoing descriptions were prepared from the 
holotype and allotype in the United States National Museum. The 
material was collected by H. E. Burke. Four other specimens col- 
lected by Burke at the same location and from the same host were also 
studied.

Phloeosinus setosus Bruck, Can. Ent., vol. 65, p. 54, 1933.—W. J. CHAMBER- 
LIN, Bark and timber beetles of North America, p. 172, 1939. 
Male.—Black, with elytra reddish brown to piceous; 1.5-2.5 mm. 
long, about 1.94 times as long as wide. 
4 Not ‘densely clothed with short, scale-like hairs,’ as described by Bruck. The apparent 
scalelike structures are fragments of frass adhering to the surface at bases of hairs.
