PANTOMORUS OF AMERICA NORTH OF MEXICO 15 
width and distinctness, and often partially interrupted here and there by scaly 
patches; laterad of the black stripe is a broad stripe of whitish scales covering 
interval 7 throughout, covering 8 from base to middle or beyond, and 6 from 
apex to about apical third. Body beneath scaly and setose; abdomen transversely 
aciculate, very sparsely punctulate medially, scaly and setose on sides of sternites 
1 to 4, setose only in a broad, median stripe and on most of sternite 5, intercoxal 
piece about seven-ninths as wide as a hind coxa; metasternum very short, dis- 
tance between hind and midcoxae hardly greater than half width of midcoxa. 
Legs with rather dense, chiefly prostrate setae but also with a few slender 
seales and some inclined bristlelike setae; fore tibia with short, blunt denticula- 
tions which are shorter than in Jeucoloma; corbel plate narrow, poorly defined, 
not scaly but often with a few short, stout spinules, dorsal comb a little shorter 
than distal. Asin /ewcoloma, the stylus of one or both coxites is sometimes absent. 
Type locality——Mississippi (Gulfport). 
Distribution —Mississipp1 (Gulfport, Saucier, Landon, McHenry). 
Type.—Female (September 3, 1937, Gladney and Padgett) and 169 
paratypes, Cat. No. 52355, United States National Museum. 
Described from 170 specimens, most of them collected at Gulfport, 
Miss., on September 3, 1937, by Gladney and Padgett, or at Saucier, 
September 8, 1937, by Dopson, Padgett, and Baker. Pantomorus 
peregrinus is probably indigenous to South America, but it does not 
seem to agree with any of the numerous descriptions examined by the 
writer. As far as known, it was first found in the United States at 
Gulfport, Miss., August 22, 1937, by H. Gladney. It resembles /ewco- 
Joma in a general way and its habits are probably similar. All speci- 
mens at hand are females and it is reasonably certain that peregrinus, 
like Zeucoloma, is parthenogenetic. 
In addition to the differences already noted, peregrinus and leuco- 
loma differ in some relative and average characteristics that are 
obvious when the two species are compared. Such differences are the 
following: 
P. peregrinus. Average length about 8.5 mm.; body stouter, head thicker; 
rostrum shorter, its median groove less widened anteriorly, subapical area more 
feebly impressed; eye shorter and a trifle more convex; scape reaching farther 
past eye, funicular segment 2 relatively shorter; pronotal punctures finer; black 
stripe bordering inner margin of white stripe usually conspicuous; longer 
elytral setae darker, fine but rigid, and not kinky at tips; blackish subglabrous 
area along middle of abdomen conspicuous; ridge on posterior face of hind tibia 
feebler to obsolescent. 
P. leucoloma. Average length about 9.5 mm; body less stout, head not so 
thick; rostrum longer, its median: groove considerably widened anteriorly, sub- 
apical area more strongly impressed; eye longer, less convex; scape relatively 
shorter, funicular segment 2 relatively longer; pronotal punctures coarser; 
elytral black stripe rarely conspicuous; longer elytral setae usually white, 
their tips very fine and often somewhat kinky; blackish median area on abdo- 
men less distinct; ridge on posterior face of hind tibia more prominent. 
ATRICHONOTUS, new subgenus 
Seales dense, setae prostrate. Head not constricted, interocular distance 
greater than length of rostrum (about 5 to 4) ; eye distinctly elliptical; rostrum 
slightly tapering, nasal plate feeble, mandibles thick, not, or feebly, subangulate 
on mesal edge above, support slightly elevated, scar facing forward or somewhat 
laterad; scape slightly exceeding eye, funicular segment 1 at least as long as 2. 
Prothorax broadly rounded laterally, hind angles in side view feeble; pronotum 
even, fore margin rounded, basal margin subtruncate, sometimes faintly promi- 
nent laterally, vestiture on median portion directed caudad, on sides directed 
transversely. Scutellum small, glabrous. Elytra with puncture row 10 obso- 
lescent medially, humeri subobsolete, basal margin of conjoined elytra broadly 
and feebly emarginate, not prominent. Body beneath and legs scaly and setose,
