Pantomorus (Phacepholis) nebraskensis Pierce, U. S. Natl. Mus. Proc. 45: 416, 
418, 1913. (New synonymy.) 
Length 5.7-8 mm. Light gray or grayish brown or occasionally dark brown, 
the pronotum usually without, sometimes with, a median and a lateral brown- 
ish stripe, the elytron of darker specimens occasionally with pale stripe on 
third, or on third and fifth, intervals. Seales dense, setae Sparse and short. 
Rostrum with subapical area impressed, latero-marginal carina moderate and 
intercarinal area subplanate (usually in female) or carina strong and inter- 
carinal area more or less concave (usually in male), median groove usually 
coarse and reaching or exceeding hind margin of eye; eye elliptical and feebly 
convex in male, a little more convex and more nearly circular in female; scape 
slightly exceeding eye, funicular segment 2 longer than 1. Prothorax wider 
than long, rather strongly angulate on hind margin opposite elytral humerus, 
not or slightly narrowed in basal half in female, more distinctly narrowed in 
male; pronotum feebly to moderately convex longitudinally, usually more con- 
vex in male, irregularly rugo-verrucose, scales forming radial clusters here 
and there, Median groove present, basal margin moderately bisinuate, basal 
transverse groove usually well impressed, hind angles acute and more or less 
projecting obliquely. Scutellum small to rather large, scaly. Elytron of male 
with basal margin somewhat thickened from scutellum to interval 5, not, or 
more feebly, thickened in female, humerus rounded or, especially in male, 
subangulate; intervals slightly to distinctly convex, the alternate (odd) ones 
sometimes more prominent than the even, interval 1 sometimes moderately 
prominent basally; setae often longer and a little more numerous on the odd 
intervals, especially on interval 1, but in general forming a subregular to stag- 
gered single row on each interval, the setae usually separated one from the 
other by more than the length of a seta. Abdomen beneath with vestiture 
finer and sparser medially in male, sometimes slightly finer and sparser medi- 
ally on sternites 3 to 5 in female; intercoxal piece considerably narrower than 
a hind coxa, sternite 5 with a broad, shallow emargination at apex in female, 
longer and with the apex broadly truncate to feebly emarginate in male, 
sternite 2 of male with three to seven or eight denticulations of variable sizes 
and prominence. Fore tibia with six or nine teeth, middle tibia of female with a 
few denticles, middle and hind tibia of male with a few short teeth or denticles. 
Median lobe rather abruptly widened basally (fig. 4, J). 
Type locality—Of candidus, Colorado to Kansas; of nebraskensis, 
Nebraska (Lincoln). 
Restricted type locality.—Colorado. 
Distribution—South Dakota (Fort Pierre, three females and one 
male from stomach of toad Bufo cognatus, No. 654, Biological Sur- 
vey); Nebraska (Lincoln, McCook); Kansas and western Kansas; 
Colorado (Grenada) ; Montana (Otter Creek, June 28, one head from 
stomach of toad, Bufo woodhousti, No. 165, Biological Survey) ; 
Wyoming (Newcastle). 
Lectotype-——A Colorado female in the Horn collection at Philadel- 
phia, marked “Lectotype 2834.” Type of nebraskensis, female, No. 
14650, in United States National Museum. 
The Montana record is based on a head of candidus taken from a 
toad’s stomach which contained also one fairly complete specimen 
of Pantomorus planitiatus. 
Horn described candidus from two specimens from Colorado and 
Kansas. The lectotype at Philadelphia undoubtedly is-Horn’s Colo-
