NEW SPECIES OF BARK BEETLES—BLACKMAN 191 
rounded; sides nearly regularly arcuate from base to the moderate 
anterior lateral constriction, moderately broadly rounded in front, 
with anterior margin weakly serrate; dorsal contour even, without ele- 
vated summit or transverse impression; anterior area with close, low, 
irregularly arranged asperities, continued at sides well behind middle, 
with fine, short hairs; posterior area finely, shallowly punctured, usu- 
ally with lateral rim of each puncture elevated; median line slightly 
elevated and impunctate, extending from base nearly to middle. 
Elytra very slightly wider than pronotum, 1.60 times as long as 
wide, 1.52 times as long as pronotum; sides very feebly arcuate, 
broadly rounded behind, conjointly rounded at apex; surface smooth, 
brightly shining; strial rows fairly regular, only first stria impressed 
on disk and sides, punctures fine and very shallow; interspaces flat, 
finely regulose, impunctate on disk and sides, surface reticulate. 
Declivity moderate; suture wide, slightly elevated, devoid of granules; 
first stria weakly impressed, its punctures obsolete; lateral elevations 
low, scarcely higher than low sutures, devoid of granules; apical por- 
tion of declivity with a few fine, erect hairs. 
Male.—Similar to female in habitus; frons convex above, broadly, 
transversely impressed between eyes, brightly shining, with punctures 
sparser and not so fine as in female, median carina weakly developed. 
Type locality.—Paraiso, Panama Canal Zone. 
Host—Unknown. 
Type material_——Holotype and allotype, U.S.N.M. No. 56007. 
The holotype and allotype were collected at Paraiso, Canal Zone,

PLATE 20, Ficures 8, 9 
Female —Reddish brown, with elytra often darker, 1.51-1.91 mm. 
long; holotype 1.80 mm. long, 2.42 times as long as wide. 
Frons feebly shining, flattened from eye to eye, on nearly circular 
area, finety, moderately closely punctured, with hairs fine and rather 
short over most of surface, but with those on margin above level of 
eyes much. longer and slightly coarser, extending nearly to epistoma 
in a rather thin veil; median carina lacking. Eye very large, coarsely 
faceted, about one-third divided by emargination. Antenna (fig. 8) 
with club obovate, 1.86 times as long as wide, 1.80 times as long as 
funicle; first suture strongly arcuate, strongly, nearly completely 
septate, second and third more strongly arcuate, not septate, indicated 
by rows of setae. 
Pronotum 1.01 times as long as wide, widest through base, posterior 
outline feebly arcuate, posterior angles not rounded, sides with pos- 
terior half nearly straight and subparallel, then moderately, arcuately
