REVISION OF THE GENUS PHLOEOSINUS—BLACKMAN 445 
sparsely punctured and subgranulate above; moderately deeply and 
widely concave between eyes, with a median carina on lower half, 
rather weakly elevated except just above epistomal margin, smooth 
above in median line; hairs short, fine, inconspicuous. Eyes more than 
three times as long as wide, about half divided by a U-shaped emargi- 
nation. Antenna with club nearly twice as long as wide, all sutures 
oblique and sinuate. 
Pronotum about 1.08 times as wide as long, widest near posterior 
angles; sides feebly arcuate and convergent on posterior two-thirds, 
then more rapidly narrowed, constricted just behind the broadly 
rounded front margin; surface shining, with close, deep, moderate- 
sized punctures on disk, which become smaller and denser near ante- 
rior margin, closer, rougher, and subgranulate on sides; lateral calli 
small; median line broadly, weakly elevated from posterior border to 
center of disk; hairs rather numerous, but short, inconspicuous except 
in profile, slightly longer at each side anterior to lateral calli. 
Elytra scarcely wider than pronotum, about 1.20 times as long as 
wide (slightly stouter than in cristatus) ; sides subparallel on ante- 
rior two-thirds, very broadly rounded behind; surface brightly shin- 
ing; striae moderately narrow, moderately strongly impressed, strial 
punctures moderately small, not longer than wide, separated by consid- 
erably more than own diameter; interspaces wide, convex, densely, 
finely punctate, with granules less numerous than in cristatus, confused 
in arrangement, with little tendency toward becoming uniseriate on 
disk; hairs numerous, short, and fine on anterior disk, becoming scale- 
like on posterior disk and declivity, inconspicuous except in profile. 
Declivity sloping as in cristatus,; first interspace narrower than on 
disk, weakly convex, finely, moderately closely punctured, devoid of 
serrations; second interspace wider than first, shining, finely, deeply, 
moderately closely punctured, without serrations; third interspace 
strongly elevated, with coarse, closely placed, dark-colored, blunt ser- 
rations, finely punctured; fifth and seventh interspaces each with four 
to eight smaller, sharper serrations; sixth and eighth interspaces with 
two to five small granules; declivity rather sparsely clothed (more 
sparsely than in ertstatus) with small scalelike hairs. Mesosternum 
flat, with anterior portion scarcely at all oblique. 
Female.—Similar to male in general habitus; frons wider between 
eyes than in male, frontal rectangle about 0.57 as long as wide; 
convex, indefinitely impressed between eyes, surface shining, rather 
finely, densely granulate-punctate except in median area above, 
median carina scarcely elevated on lower half, more or less broken 
up by granules but elevated into a small tooth on epistomal margin; 
elytra with interspaces on disk more strangly granulate than in male,
