PANTOMORUS OF AMERICA NORTH OF MEXICO 31 
The eye in viridis varies considerably in shape and in degree of 
convexity. It is rounded to slightly elliptical in both sexes, and 
usually is a little larger, more convex, and more elliptical in the male. 
The narrowing of the head behind the eyes is usually perceptible, 
and in general better developed than in any of the other forms 
of elegans. A marked convexity of the pronotum in profile is one 
of the distinctive features of viridis, though sometimes the pronotum 
is no more convex than in certain specimens referred to pallidulus. 
The prothorax of the male, as is often the case in other species of 
Phacepholis, is larger, compared with the elytra, than in the female. 
Pantomorus viridis usually can be told by the broad and laterally 
rounded elytra, the strong convexity of the pronotum and elytra in 
profile, and the strongly convex eyes.

Length 4.75-6.5 mm. Stout, elytra feebly rounded laterally. Usually gray, 
brownish gray, or brown, with or without evident metallic tinge, sometimes 
greenish gray to green with distinct metallic tinge, a narrow vitta usually 
present on lateral interval of elytron. An extremely variable color pattern 
sometimes present as follows: Prothorax with a pale, greenish or coppery lateral 
vitta opposite eye and a similarly colored, curved, vague, and incomplete dorsal 
vitta each side of middle; elytron with interval 3 pale at base and sometimes 
nearly throughout, interval 2 occasionally pale for a greater or less distance 
basally, intervals 7 and 8 in apical half to three-fourths and intervals 9 and 10 
in basal fourth also pale; greenish specimens sometimes with a common, cop- 
pery vitta on intervals 9 and 10 in apical half. The above markings occur in 
various combinations on different specimens. A few specimens, including the 
type series, are a nearly unicolorous gray. 
Head not, or slightly, narrowed behind eyes, eyes rounded to elliptical, moder- 
ately to strongly convex; rostrum usually subplanate above, sometimes slightly 
impressed, scape exceeding eye, funicular segments 1 and 2 subequal or 2 
slightly to moderately longer than 1. Prothorax distinctly narrowed basally, 
basal angles usually projecting slightly; pronotum scarcely to distinctly eonvex 
longitudinally in profile, basal margin subtruncate to feebly bisinuate, median 
groove obsolete or nearly so, at most feebly defined, surface rugo-punctate, scales 
smaller at middle than, on either side, often forming fairly distinct radial 
clusters on the elevations. Elytron in most females feebly declivous basally, 
more strongly so in most males, intervals subplanate to slightly convex, scales 
small and in general not overlapping, setae blunt and short, in about three ir- 
regular rows on each interval. Abdominal sternite 5 of female short, sternite 2 
of male usually without denticles, rarely with minute ones, sometimes with a 
curved, transverse ridge as in elegans. Legs a little stouter, and denticulations 
on fore tibia a little longer, than in the other varieties of this group. 
Type locality —Texas (Corpus Christi). 
Distribution—Texas (Victoria, Beeville, Gregory, Sharpsburg, 
Sinton, Wades, Brownsville). 
Type—Female, May 17, 1905. No. 13123, United States National 
Museum. 
Reported on cotton at Corpus Christi, Victoria, Sinton, and Kings- 
ville; on Leucasyris spinosa at Gregory; feeding on sugar beets at 
Brownsville. Most of the 32 specimens were collected in May, a few 
in March, April, and June and 2 from Brownsville in January. 
In its typical form, pallidulus is recognizable by its small size, 
stout form, predominantly gray or brown color, feeble convexity of
