PHLOECSINUS KEENI, new species 
Male—Piceous to black, with posterior elytra reddish to piceous 
brown; 2.15 to 2.8 mm. long, holotype 2.57 mm., about 2.04 times 
as long as wide. 
Frons wide between eyes, frontal rectangle about 0.70 as long as 
wide; epistomal margin slightly thickened, epistomal lobe moderately 
short; central area broadly, deeply concave, finely, closely granulate- 
punctate at sides and above, concavity shining and impunctate in 
median fourth, finely granulate-punctate on the slopes at sides and 
above, with a rather indistinct, not sharply elevated median carina 
in lower half of concavity; hairs moderately short, cinereous, incon- 
spicuous except in profile. Eye about 2.7 times as long as wide, 
more than half divided by a broad V-shaped emargination. An- 
tenna with club slightly less than twice as long as wide, first two 
sutures slightly but distinctly oblique, third suture strongly, sinu- 
ately oblique. 
Pronotum about 1.14 times as wide as long, widest just behind 
middle, sides feebly diverging to the widest point, then strongly, 
arcuately narrowed, constricted just back of the broadly rounded 
anterior margin; surface shining, transversely impressed behind 
front margin; disk with close, deep, moderately fine punctures, 
slightly rougher at sides; elevated median line lacking; lateral calli 
rather poorly developed, sometimes lacking; pubescence short and 
fine, inconspicuous except when seen in profile. 
Elytra wider than pronotum, nearly 1.30 times as long as wide, 
slightly wider at about middle; sides subparallel on anterior two- 
thirds, broadly rounded behind; surface moderately shining on disk; 
striae narrow, impressed on disk, wider behind and on sides, strial 
punctures small, rather close; interspaces several times as wide as 
striae, moderately finely, closely punctate-granulate, the granules con- 
fused on disk, with a uniseriate row of larger asperities on first, 
third, and alternating interspaces, starting near summit of declivity;
