HYLASTES WEBBI, new species’ 
Female.—Dark reddish brown, 5.04 mm. long, about 2.85 times as long as 
wide. 
Frons broad between the eyes, frontal rectangle 1.05 times as long as wide; 
dark reddish brown above, light brownish red below and on epistoma, with 
epistomal margin piceous, thickened, and liplike, its median lobe short, wide, 
and weakly emarginate at end; epistoma moderately deeply and broadly im- 
pressed at each side, divided by the median carina, which is rather wide, low, 
and coriarious below, finer and Sharper above, ending in the moderately deep 
and wide, arcuate transverse impression; surface subopaque, finely, closely, 
rather shallowly punctured, subgranulate; hairs fine, short, recumbent, incon- 
spicuous, slightly longer and directed downward on epistoma, with a group 
of two much longer hairs, symmetrically placed at each side of epistomal lobe. 
Hye finely granulate, about twice as long as wide, widest above, inner margin 
entire. Antenna with first joint of club slightly longer than other three com- 
bined. 
Pronotum distinctly narrower than elytra, about 1.19 times as long as wide, 
widest at or slightly behind middle; posterior outline feebly arcuate, posterior 
angles rounded, sides moderately, almost evenly arcuate, but very feebly con- 
stricted in anterior fourth, rather broadly rounded in front; surface shining; 
punctures moderately coarse, close, often in small irregular lines of from two 
to eight punctures with the intervening partitions lacking or very fine and low, 
the interstices elsewhere wider, higher, and brightly shining; punctures closer 
and much smaller in front; sides densely and finely asperate-punctate; median 
line moderately narrow, slightly elevated, lacking on anterior fourth; hairs 
minute, scarcely extending beyond rim of punctures on disk, slightly larger on 
sides and behind. 
Elytra distinctly wider than pronotum, about 1.92 times as long as wide: 
sides subparallel on anterior two-thirds, then gradually narrowed, with the 
apex narrowly rounded; surface moderately shining; striae moderately im- 
pressed on disk, more strongly on sides and declivity; punctures coarse, moder- 
ately close, slightly less so than in nigrinus; interspaces slightly narrower than 
striae, rather strongly convex, more strongiy on sides and declivity, finely, 
confusedly punctured and confusedly, moderately granulate; disk appearing 
glabrous, but with a few minute, irregularly arranged hairs, more abundant, 
coarser, and longer on declivity, and to a less extent on sides. Declivity slop- 
ing, interspaces more strongly convex, first and third somewhat more strongly 
elevated, granules slightly coarser than on disk, not uniseriate; ninth interspace 
wide, moderately elevated behind. 
Last sternite of abdomen moderately rounded, strongly convex near base, less 
so toward tip; punctures of moderate size, finer, closer, and rougher near apex; 
hairs minute, appressed, inconspicuous. 
Male.—Similar to female in size and proportions, slightly more coarsely punc- 
tured: last abdominal sternite shorter, very broadly rounded, subtruncate 
behind, moderately punctured near base, finely and densely at tip, impressed 
in median line behind, and ornamented with longer and more numerous hairs 
in groove. 
Type locality—Elmore, 8. Dak. 
Additional locality—Kalispell, Mont. 
Host—Not definitely known, probably Pinus ponderosa Laws. 
Holotype, allotype, and four paratypes.—U. S. National Museum 
No. 54033.
