REVISION OF THE GENUS PHLOEOSINUS—BLACKMAN 423 
Frons broad between eyes, frontal rectangle about 0.72 as long as 
wide, epistomal lobe short; moderately broadly, not deeply concave 
between eyes, with a very strongly elevated median carina on more 
than the lower half; surface shining, black, finely and closely punc- 
tate-granulate at sides, roughly punctured in median area above con- 
cavity, granules finer in concavity; vestiture of fine, short, inconspicu- 
ous hairs. Eye more than three times as long as wide, more than 
half divided by a very broad emargination. Antenna with club about 
1.6 times as long as wide, first two sutures slightly oblique, third 
suture strongly oblique. 
Pronotum about 1.20 times as wide as long, widest at posterior 
angles, sides nearly regularly arcuate from base to lateral constric- 
tion just behind moderately rounded front margin; surface black, 
moderately shining, broadly, transversely impressed in anterior third, 
with very deep, close, moderate-sized punctures on disk, anterior 
portion more closely punctured and subgranulate, sides roughly, sub- 
granulately punctured; median line not elevated; lateral calli very 
small or lacking; vestiture rather short and fine, somewhat longer 
at sides. 
Klytra wider than pronotum, about 1.24 times as long as wide; 
sides nearly straight and subparallel on anterior two-thirds, broadly 
rounded behind; surface brightly shining, reddish brown to 
nearly black; striae very deep, more than half as wide as interspaces, 
punctures of moderate size, rather deep, separated by more than own 
diameters; interspaces convex, confusedly granulate-punctate on an- 
terior third of disk, strongly rugose and uniseriately asperate behind, 
asperities transverse, with one, two, or more punctures at posterior 
base of each, each giving rise to an erect, rather short seta, punctures 
and setae more numerous on sutural interspaces behind middle of 
disk. Declivity with first and third interspaces strongly convex, 
sparsely asperate, densely and finely punctured, with erect setae as 
on disk and with more numerous, flat, scalelike, nearly white hairs, 
very numerous on first interspace, forming a white stripe, less numer- 
ous on third interspace, second interspace weakly convex, with surface 
brightly polished and bare, devoid of serrations but with a few 
minute, obsolescent punctures; more lateral interspaces all finely as- 
perate, with less numerous hairs. Anterior face of mesosternum 
steep. 
Female.—Similar to male in size and general appearance; frons 
very wide between eyes, frontal rectangle about 0.66 as long as wide, 
coarsely, densely granulate-punctate, broadly, transversely impressed, 
median carina less strongly elevated than in male; elytral declivity 
similar to that of male but with serrations slightly smaller.
