426 PROCEEDINGS OF THE NATIONAL MUSEUM VOL, 92 
piceous black, shining, punctures deep, somewhat sparser than usual, 
of moderate size; lateral calli lacking, the disk indefinitely impressed 
at each side of median line on posterior fourth; pubescence fine, short, 
and inconspicuous, only slightly longer at each side just anterior to 
position of lateral calli. 
Elytra wider than pronotum, about 1.35 times as long as wide; 
sides nearly straight and subparalle! on anterior two-thirds, broadly 
rounded behind; surface brightly shining, striae rather deeply im- 
pressed, much narrower than interspaces, strial punctures small, nar- 
row, and elongate, not very close; interspaces wide, convex, surface 
granulate—punctate, with granules sparse, confusedly asperate near 
base, rounded and confused on most of disk, becoming uniseriate on 
alternate interspaces posteriorly, punctures rather fine, with a few 
very fine, short hairs. Declivity with all of interspaces slightly 
convex, first and third scarcely more convex than second, surface 
nearly smooth, with asperities nearly obsolete, those on ninth inter- 
space slightly larger than on others, second interspace subequal to 
first, narrower than third. Anterior face of mesosternum moderately 
oblique. 
Female.—Similar to male in appearance, with frons convex, closely 
punctate-granulate below, more sparsely punctured above, with a 
fine, acute median carina on lower half, with frontal rectangle about 
0.70 as long as wide; elytral interspaces slightly more strongly (but 
still weakly) asperate on declivity than in male. 
Type locality —Fresno County, Calif. 
Host—“Cedar limbs.” 
Location of type-—Canadian National Collection No. 2178. 
Remarks—Numerous specimens in the United States National 
Museum were taken at various localities in California and southern 
Oregon, mostly from Lzbocedrus decurrens Torrey unc in one case 
from Thuja plicata D. Don. 
Phloeosinus russus was described by Swaine as of about the same 
size as, and closely allied to, vandykei Sw.; more teebiy shining, with 
short, easily seen pubescence; with elytral interspaces more convex, 
and with uniseriate asperities, large on disk and smaller on declivity. 
The species was described from a single female specimen labeled 
“S. B. Mts. (San Bernardino Mountains?), Cal. 7/19/92.” The de- 
scription is very brief, and, if I have interpreted it correctly, it 
apples very closely to several specimens selected from the rather 
long series of vandyket showing coarser elytral sculpture and more 
evident vestiture. It is believed that P. russus Swaine should be 
placed as a synonym of P. vandykei Swaine.
