REVISION OF THE GENUS PHLOEOSINUS—BLACKMAN 447 
with punctures somewhat larger and sparser, subgranulate above; 
impressed to shallowly concave between eyes, with an indistinct, 
feebly elevated median carina on lower half; hairs short, fine, and 
inconspicuous. Eye more than three times as long as wide, more 
than half divided by a broad U-shaped emargination. Antenna with 
club about twice as long as wide, first two sutures slightly oblique, 
third strongly oblique. 
Pronotum about 1.09 times as wide as long, widest at posterior 
angles; sides nearly straight and very feebly convergent on posterior 
half, then strongly arcuately convergent, constricted just behind 
the broadly rounded anterior margin; surface brightly shining, with 
deep punctures of moderate size and density (slightly finer and 
sparser than in cristatus), closer and finer near anterior margin, 
rougher and subgranulate on sides; lateral calli small, almost lack- 
ing; median line feebly elevated only on posterior eighth; hairs very 
fine and short, very inconspicuous, surface appearing glabrous. 
Elytra scarcely wider than pronotum, about 1.40 times as long 
as wide; sides subparallel on anterior two-thirds, very broadly 
rounded behind; surface brightly shining; striae narrow, distinctly 
impressed, strial punctures fine, not close; interspaces wide, moder- 
ately convex, with rugae and low, transverse granules, very fine 
punctures bearing minute hairs. Declivity (pl. 40, figs. 19, 19a) 
steep, brightly shining; first interspace feebly convex, devoid of 
serrations, with only a few, fine, obsolescent punctures; second in- 
terspace flat, brightly shining, narrowed posteriorly and becoming 
obsolete on apical sixth, with no serrations and only a few obso- 
lescent punctures; third interspace very strongly elevated, with very 
coarse, black serrations; fifth, seventh, and ninth interspaces each 
with a few moderately coarse, black serrations; sixth and eighth 
interspaces each with a few granules or small serrations; declivity 
nearly glabrous with only a few small hairs on the more lateral inter- 
spaces. Mesosternum with anterior portion somewhat oblique. 
Female——Similar to male in general habitus; frontal rectangle 
about 0.65 as long as wide; convex, impressed between eyes, with 
median carina elevated and distinct on lower half, densely granulate- 
punctate at sides, more coarsely punctured and subgranulate above; 
elytral declivity (pl. 40, figs. 18, 18a) shining, first interspace moder- 
ately elevated, with a few granulelike serrations and a few very 
small punctures; second interspace narrowed behind, becoming ob- 
solete on posterior eighth, devoid of serrations and with a few very 
fine punctures; third interspace strongly elevated, with a row of 
black, moderately coarse serrations; lateral interspaces with a few 
moderate serrations on fifth, seventh, and ninth, and with small
