NEW SPECIES OF BARK BEETLES—BLACKMAN 219 
Elytra slightly wider than pronotum, about 1.72 times as long as 
wide; sides nearly straight and subparallel on anterior three-fourths, 
then narrowed to the acuminate point, produced at sutural angles; 
surface feebly to moderately shining; strial punctures small, moder- 
ately shallow, in nearly regular strial rows, only first striae distinctly 
impressed; interspaces of moderate width, flat, distinctly rugulose, 
nearly impunctate except near declivity; disk nearly glabrous, sides 
with a few small hairs. Declivity with rather shallow sulci each side 
of the elevated, finely granulate suture; punctures of first and second 
striae obsolete; second interspace shining, impunctate; lateral con- 
vexities no higher than suture, with a few obsolescent granules in 
third interspace, hairs fine, erect, rather short. 
Male.—No unmistakable male of this species was seen, but several 
specimens that may possibly be males have the frontal vestiture 
shorter and the declivital vestiture considerably longer than in the 
female perotei. 
Type locality —FPerote, Veracruz, Mexico. 
Host.—Pinus teocote. 
Type material—Holotype and 14 paratypes, U.S.N.M. No. 55992. 
The type material was collected from Pinus teocote at Perote, Vera- 
cruz, New Mexico, by Donald DeLeon, February 9, 1936. 
PITYOPHTHORUS SPADIX, new species 
Female.—Dark reddish brown, 2.4-3.1 mm. long; holotype 2.80 mm. 
long, about 3.06 times as long as wide; allied to confertus Swaine. 
Frons flattened on a nearly circular area extending about three- 
fourths of distance between eyes, with an indented peripheral margin; 
finely and densely punctured, with numerous moderately long, fine 
hairs, those at periphery longer and incurved. Eye moderately 
faceted, about half divided by a deep, rather wide emargination. 
Antennal club oval, much longer than funicle, widest through second 
segment; first two sutures weakly arcuate, partially septate, third 
suture strongly arcuate, with septum entirely lacking. 
Pronotum about 1.12 times as long as wide, widest at posterior 
angles; posterior margin weakly arcuate, posterior angles rounded; 
sides nearly straight and feebly converging on posterior two-thirds, 
very feebly constricted in front of middle, very broadly rounded in 
front; anterior margin armed with 8 to 10 broad, low serrations; 
anterior area with irregular, concentric rows of broad, low asperities; 
summit moderate, with a distinct broad, transverse impression poste- 
rior to it; posterior area with deep, rather close, moderately coarse 
punctures, interstices reticulate; median line not wide, scarcely ele- 
vated behind, strongly elevated across transverse impression; disk 
weakly shining, appearing glabrous, sides with small, inconspicuous 
hairs.
