PANTOMORUS OF AMERICA NORTH OF MEXICO ~ 33 
second funicular segment is shorter than in viridis and more as in 
typical eawimius. The body form is more slender than in either viridis 
or eximius, and here, as well as in its somewhat larger elytral scales, 
it resembles the variety elegans. On the strength of its setose corbel 
plate, the Cotulla male is tentatively referred to eximzus, though ex- 
cluded from the type series. 
The vestiture on the corbel plate appears to be a. dense mat of 
subprostrate setae agglutinated by a varnishlike substance. In one or 
two specimens some of the setae are fairly distinct, but in most cases 
the individual setae cannot be clearly detected even after treatment 
with potassium hydroxide. When picked apart with a needle, the mat 
of setae disintegrates into minute, flakelike pieces each of which may be 
a seta imbedded in the cementing agent. This vestiture, though its 
exact nature is doubtful, evidently is different from the coating of true 
scales that is found on the corbel plate of the other species and 
varieties of Phacepholis. 
Pantomorus eximius seems most closely related to viridis, but differs 
by having the eye decidedly less convex (except in the Cotulla male), 
the form less stout, the second funicular segment averaging shorter, 
the color usually duller, and the corbel plate setose. The denticles on 
male abdominal sternite 2 are larger than in any other variety of the 
elegans group. 
The convexity and shape of the eye vary considerably in different 
specimens of eavmius,; in general, the eye is longer and larger, but no 
more convex, in the male than in the female. 
The candidus group differs as a whole from the elegans group in 
having the general vestiture denser, the elytral scales larger and flat, 
the prothorax more distinctly produced forward above, the scutellum 
larger and usually densely scaly, the elytral intervals sometimes rather 
strongly convex, the denticles on abdominal sternite 2 of male larger, 
‘and the hind tibia usually with small but distinct denticulations in 
the male; the abdominal vestiture usually is finer and sparser medially 
in the male, sometimes a little sparser and finer medially on sternites 
3 to 5 in the female. 
KEY TO SPECIES OF THE CANDIDUS GROUP 
1. Funicular segment 2 almost twice as long as 1; setae rather fine, many 
of them tapering, those on even intervals of elytra uniseriate in gen- 
eral; about 15 spinules in distal comb. Texas. 
(11) teranellus, new name (p. 34). 
Funicular segment 2 relatively shorter, often subequal to 1; elytral setae, 
if fine and tapering, usually irregularly biseriate on some portions of 
even intervals. North of Texas (except obscurus)—----_---______-- 2 
2. Elytral setae sparser and, except some of those on interval 1, blunt, sub- 
parallel sided, those on even intervals uniseriate in general; funicular 
segment 2 longer than 1, usually considerably so; eye rather feebly 
convex and, in male, distinctly elliptical; distal comb with about 17 
Oreslsespimules = tS eee (12) candidus (Horn) (p. 35). 
Elytral setae longer and more abundant, fine, tapering, those on even 
intervals usually irregularly biseriate in general; funicular segment 2 
shorter, often subequal to 1, though sometimes slightly but plainly 
longer than 1; eye more strongly convex and more nearly circular in

3. Average length about 6 mm; median groove on pronotum usually present 
though often obscured by the scales; spines on fore tibia relatively 
shorter, often six or seven larger and several shorter ones (fig. 3, J) ; 
about 14-16 spinules in distal comb.
