REVISION OF THE GENUS PHLOEOSINUS—BLACKMAN 439 
broadly rounded front margin; surface piceous, brightly shining, 
rather closely, deeply, coarsely punctured on disk (more coarsely 
than in bawmanni), very finely and densely near anterior margin; 
lateral calli better developed than in bawmanni; hairs moderately 
short and fine, more conspicuous than in bawmanni, much longer and 
more conspicuous on a considerable area at each side anterior to 
lateral calli. 
Elytra only feebly wider than pronotum, about 1.2 times as long 
as wide, widest at base; sides nearly straight and subparallel on 
anterior two-thirds, very broadly rounded behind; surface piceous, 
shining; striae distinctly but weakly impressed, strial punctures very 
coarse (even coarser than in bawmanni), very closely placed; inter- 
spaces no wider than striae midway on disk, very strongly, rather 
coarsely rugose and strongly granulate-punctate (sculpture distinctly 
coarser than in dawmanni), with granules coarse, confused anteriorly 
on disk, becoming uniseriate posteriorly; hairs more abundant, 
longer and more conspicuous than in bawmanni. Declivity (pl. 39, 
figs. 15, 15a) very abrupt, serrations coarse, blunt, and black, first 
interspace with two to five large, black serrations at summit of 
declivity, with apical five-sixths broad, nearly flat, shining, roughly, 
rather coarsely punctured, rarely with one or two rather small, vestig- 
ial serrations; second interspace much narrower than first or third, 
widened at apex, shining, punctured; third interspace strongly 
elevated, with very coarse, closely placed, black serrations; fifth, 
seventh, and ninth interspaces elevated, each with several rather 
coarse, black serrations; declivital interspaces all sparsely clothed 
with small scalelike hairs, with a few slender hairs at bases of 
serrations. Mesosternum slightly oblique in front. 
Female.—Similar in habitus to male; frons wider between eyes than. 
in male, frontal rectangle about 0.64 as long as wide, weakly convex, 
transversely impressed between eyes, densely granulate-punctate ex- 
cept in median line above; median carina much stronger than in 
baumanni; finely, sharply elevated, toothlike on epistoma; elytral 
declivity (pl. 39, figs. 14, 14a) with first and third interspaces 
strongly elevated and with coarse, black serrations (stronger than in 
baumannt), second interspace very narrow but widened near apex; 
first three interspaces moderately clothed with numerous short scales 
and with a few hairlike setae.
