narrower on declivity and with asperities more prominent; disk subglabrous, but 
with more numerous, short, fine, rather inconspicuous hairs on sides and declivity. 
Mesosternum with anterior face precipitous between the middle legs; first and 
last abdominal sternites subequal, and each about as long as middle three ecom- 
bined; last sternite ascending posteriorly, convex in section, rather narrowly 
rounded behind, roughly, rather finely punctured. 
Male.—Very similar to female, but with the pronotum slightly more slender 
(about 1.12 times as long as wide); last abdominal sternite somewhat more 
broadly rounded behind; ventral surface not impressed or ornamented with 
longer hairs in median line. 
Remarks.—The foregoing description of the female was prepared 
from one of the two cotypes before EKichhoff (Kichhoff and Schwarz 
1896, p. 607) when the original description was drawn up. The pres- 
ent writer also studied 11 additional specimens taken at several locali- 
ties in North Carolina and South Carolina and at Call, Tex. The host, 
when indicated, was longleaf pine (Pinus palustris Miller) and “pine.” 
As Eichhotf points out, scobinosus is closely allied to salebrosus, the 
two species being distinguished by him by the radically different shape 
of the pronotum. A re eading of the foregoing descriptions will indi- 
cate that other differences exist, although these are usually small. The 
short series of scobénosus shows comparatively little variation. Some 
of the specimens were taken from newly sawn lumber to which they, 
together with salebrosus, had been attracted; others were taken in 
pine bark unaccompanied by the latter.

Ent. Branch Bul. 14 (2) : 78, 79. 
Female.—Bright reddish brown, moderately shining, 4.4. mm. to 5.7 mm. 
long, about 2.9 times as long as wide. 
Irons distinctly convex, with the usual arcuate transverse impression scarcely 
indicated; only moderately wide between the eyes, frontal rectangle about 
1.17 times as long as wide; epistomal margin liplike, darker in color, epistomal 
lobe wide, concave at middle, distal end emarginate; epistoma lighter in color, 
moderately deeply and widely impressed at each side of the median carina, 
which is fine and acute on epistoma, slightly higher, rougher, and coarser above, 
ending opposite middle of eyes; surface shining, closely, moderately, rather 
roughly, subrugosely punctured, much more finely and closely on lower frons; 
pubescence short, fine, and inconspicuous. Eye rather long oval, about 2.3 
times as long as wide, definitely more slender than in allied species, only 
slightly wider above, rather finely granulate; inner line entire. Antenna with 
first segment of club slightly longer than the others combined. 
Pronotum about 1.07 times as long as wide, widest Slightly behind middle; 
posterior outline weakly arcuate; posterior angles rounded: sides distinctly 
arcuate, then moderately constricted to meet the rather broadly rounded ante- 
rior margin; surface shining, punctures of moderate size, rather close, very 
Shallow on disk, smaller and denser in front, smaller, closer, and slightly 
rugose at sides; median line somewhat elevated, wider in middle half. 
Elytra definitely wider than pronotum, almost exactly twice as long as wide; 
base truncate, with margin slightly elevated and rather feebly dentate; lateral 
angles rounded; sides subparallel for three-fourths of their length, then 
arcuately narrowed and feebly constricted, with the extreme apex very broadly 
rounded; surface moderately shining; striae scarcely impressed on disk, mod- 
erately so behind; punctures moderately coarse, very closely placed, only slightly 
smaller near base; interspaces slightly wider than striae, nearly flat on disk 
and sides, moderately convex behind and on declivity, moderately rugose-granu- 
late on disk; rugae often bridging striae in basal half. Declivity arcuate, 
sloping; interspaces distinctly convex, confusedly granulate-asperate; distinctly 
compressed at each side near apex, just above the strongly convex ninth inter- 
space. Pubescence yellowish red, short, fine, appressed, but little coarser and 
longer on declivity but more visible owing to angle of vision.
