PITYOPHTHORUS HIDALGOENSIS, new species 
PLATE 23, FiaurE 45 
Female.—Piceous-brown, with posterior part of elytra reddish 
brown, 1.57-1.85 mm. long; holotype 1.80 mm. long, about 2.74 times 
as long as wide; allied to hubbardi Blackman, but stouter and usually 
smaller. 
Frons flattened on a nearly circular area with impressed margin, 
extending from eye to eye, with central half feebly concave, finely and 
closely punctured, with numerous rather fine, yellowish hairs of mod- 
erate length, those at periphery longer and incurved. Eye moderately 
finely faceted, less than half divided by a rather narrow, angular 
emargination. Antenna (fig. 45) testaceous, with club oval, first and 
second sutures weakly arcuate, partially septate, third suture strongly 
arcuate, without septum. 
Pronotum about 1.05 times as long as wide, widest near base, pos- 
terior margin nearly straight, posterior angles somewhat rounded, 
sides nearly straight (very feebly arcuate) and subparallel on pos- 
terior half, slightly constricted before middle, moderately broadly 
rounded in front; anterior margin with nunmerous rather broad, low 
serrations; anterior area with rather low asperities in irregular con- 
centric rows; summit moderately high, at center of disk, distinctly, 
broadly impressed behind it; posterior area with small, rather deep 
punctures; median line not elevated, rather wide (wider than in 
hubbardi) ; surface usually moderately shining. 
Elytra slightly wider than pronotum, about 1.69 as long as wide; 
sides subparallel on anterior two-thirds, rather narrowly rounded be- 
hind; surface moderately shining, indistinctly reticulate; strial punc- 
tures rather close, of moderate size, in regular rows, only first striae 
impressed ; interspaces nearly impunctate anteriorly on disk, subglab- 
rous. Declivity rather sloping, brightly shining, suture normal, not 
granulate; sulcus rather shallow and narrow, punctures of first and 
second striae much reduced, obsolescent ; lateral elevations not strong, 
with several obsolescent granules on third interspace; hairs scanty and 
rather short. 
Male.——Similar to female in general habitus; frons transversely 
impressed above epistoma, transversely elevated (subcarinate) above, 
with faint median carina below, finely punctured, more sparsely than
