REVISION OF THE GENUS PHLOEOSINUS—BLACKMAN 467 
Elytra wider than pronotum, about 1.34 times as long as wide; sides 
subparallel, very feebly sinuate, on anterior two-thirds, broadly 
rounded behind; surface moderately shining; striae on disk narrow, 
rather strongly impressed, punctures fine, elongate, rather close; striae 
on sides, slightly wider, shallower, with somewhat larger punctures; 
interspaces wide and flat, finely, densely, confusedly granulate-punc- 
tate, tending to become uniseriate behind; lateral interspaces narrower, 
slightly convex; vestiture consisting of short, rather numerous hairs, 
slender and rather sparse on anterior half, becoming more abundant 
and stouter behind. Declivity with first and third interspaces moder- 
ately convex, each with a row of rather small, granulelike serrations, 
very finely and closely punctured; second interspace nearly flat, nearly 
as wide as others, closely, finely punctured, devoid of serrations; in- 
terspaces laterad of fourth all finely serrate and punctate; all inter- 
spaces with rather abundant, small, more or less scalelike hairs and 
with a few slender hairs. Anterior face of mesosternum moderately 
precipitous. 
Female.—Similar to male in general habitus, with frons wider be- 
tween eyes, frontal rectangle about 0.71 as long as wide, convex, feebly 
impressed in median area, finely, densely granulate-punctate, with a 
fine, rather indistinct median carina on lower half; elytral declivity 
similar to that of male but with smaller serrations on first and third 
interspaces; second interspace punctured and without serrations as in 
male; vestiture consisting of a few slender hairs and many flattened, 
widened, scalelike hairs. 
Type locality —Tacubaya, D. F., Mexico. 
Host.—Cupressus. 
Type material—Female type and five paratypes, U.S.N.M. 
No. 7516. 
Remarks.—The female type and five paratypes (male type ap- 
parently lost) were taken from Cupressus at Tacubaya, D. F., Mexico, 
by E. Bowmann, February 1903. In addition nine specimens taken 
from Cupressus benthami Endl. at Chapultepec August 1927, and 
nine specimens collected from Cupressus near pyramids of San Juan, 
Teotihuacan, Mexico, by D. DeLeon were studied by the writer.
