NEW SPECIES OF BARK BEETLES—BLACKMAN 189 
margin weakly serrate; dorsal contour evenly arcuate from base to 
apex, without elevated summit or posterior impression; anterior area 
with irregular, concentric rows of low, broad asperities, extending 
behind middle at sides; posterior area with surface subopaque to weakly 
shining, finely reticulate, punctures moderately fine and deep, with 
outer rim of more lateral punctures slightly elevated; median’ line 
impunctate, scarcely elevated. 
Elytra scarcely wider than pronotum, 1.55 times as long as wide, 
1.49 times as long as pronotum; sides straight and subparallel on slightly 
less than anterior two-thirds, then gradually, arcuately narrowed, with 
apex moderately broad ; surface moderately shining, finely, imperfectly 
reticulate, strial rows slightly irregular, punctures small, moderately 
shallow, only first striae impressed; interspaces flat, finely rugulose, 
with a few punctures, bearing fine, upright, light-colored hairs on disk; 
sides with strial rows still more irregular. Declivity originating well 
behind middle; first stria impressed, the others not impressed, suture 
slightly elevated, devoid of granules, lateral elevations not higher than 
suture, without granules; each of declivital interspaces with a few 
conspicuous, light-colored, erect, often stout hairs of moderate length.

versely impressed below, with fewer and shorter hairs and sparser 
punctures.

wide. 
Frons shining, convex above, broadly, transversely impressed be- 
low; punctures rather sparse, of moderate size above, smaller, finer, 
obsolescent below, with short, fine, inconspicuous hairs; median carina 
on lower half only, very weak. Eye large, coarsely faceted, less than 
one-third divided by emargination. Antenna (fig. 10) with club 
obovate, 1.28 times as long as wide; first suture notched at each side, 
arcuate, with incomplete septum; second suture indicated by row of 
setae and by notch on upper margin; third suture near distal margin
