REVISION OF THE GENUS PHLOEOSINUS—BLACKMAN 409 
epistomal margin and a small, indistinct, post-marginal callosity on 
each side, the median epistomal process small, but semicircular and 
emarginate; (in male the front is coarsely granulate-punctate, with 
a large, deep, subcordate impression occupying more than half the 
space between the eyes, and a strong median carina extending from 
the depth of the impression to the epistomal margin; the median 
epistomal process minute, lunar and entire); the antennal club 
elongate-oval, the ‘sutures’ bisinuate, subtransverse on the outer half, 
strongly recurved toward the base on the inner third. 
“Pronotum: In the female slightly longer than wide, 2.5:2, rather 
strongly constricted in front on the sides, the constriction continued 
across the dorsum as a strong postmarginal impression, the puncta- 
tion close, moderate, and subgranular, coarser than pini, with a 
smooth median line very narrow and incomplete; (in male decidedly 
wider than long, 2.2: 1.5, strongly constricted in front, with the median 
line more distinct). 
“The elytra are stout, longer than wide, 4:3; scutellum depressed, 
striae narrow and impressed, strial punctures narrow, elongate and 
deep; interspaces moderately convex, with coarse and fine granules, 
the coarser nearly uniseriate on the disc, uniseriate, sparser, and acute 
on the declivity, closer and more numerous near the base, 2nd inter- 
space wider, elevated and densely granulate near base. The declivity 
in the female with interspaces convex, 2nd not perceptibly narrower 
or less elevated than Ist and 8rd, with a single row of acute granules; 
(in the male 1st and 8rd interspaces slightly more strongly convex, 
the 3rd with distinctly coarse granules). 
“The venter is sparsely punctate, the mesosternum precipitous in 
front, elevated at the anterior angle into a short compressed process 
between the coxae, perpendicular in the female, narrower and less 
ridge-like than in pini.
