entirely colorless, but the apex and two 
spots on the inner margin are black, while 
the outer margin is marked with red. The 
membrane is marbled with fuscous, and 
the areoles are chiefly dark fuscous, with 
white veins at apices. The legs are marked 
much as in salicis, but the black color on 
the femora is irregularly broken by two or 
three large, and many small, white spots. 
Mave.—Length 5.20, width 1.90. Head 
width 1.00, vertex 0.26; frons with five or 
six oblique, reddish lines on either side of 
median line; base of tylus and spot on either 
side of basal half, dorsal margins of juga 
and lora, and slender median line on apical 
half of tylus, reddish. Rostrum, length 2.34, 
extending to fifth abdominal sternite. An- 
tennae, first segment, length 0.97, very dark 
brown, with several small, smooth white 
spots on dorsal aspect, spines pale; second,

third, 1.23, black, pale at base and at ex- 
treme tip; fourth, 0.91, black. Pronotum, 
length 0.84, width at base 1.50; propleura 
black; lower margin, and spot at top of 
coxal cleft, white; the white of lower mar- 
gin continued as a ray upon black sternum. 
Clothed with fuscous to black, simple pubes- 
cence intermixed with white, silky pubes- 
cence; more yellowish hairs on head and 
embolium than black ones. Genital claspers

This species is distinguished from allied 
ones by its general pale gray color, with a 
conspicuous black spot on the inner apical 
angle of the corium; it also is distinguished 
by the pale and black, unspotted, first an- 
tennal segment. The structure of the male 
genital claspers is distinctive, fig. 176; the 
genitalia are apparently nearest in form to 
those of buenoi Knight and schotti Knight. 
Mate.—Length 5.60, width 2.16. Head 
width 0.95, vertex 0.35; head white to yel- 
lowish, with incomplete lines on _ frons; 
marks on middle and on median line at apex, 
basal half of lora, and dorsal half -of buc- 
culae, reddish brown to fuscous; a pair of 
marks, beginning on collum and extending 
across collar and between calli, distinctly 
red orange. Rostrum, length 2.64, extend-

ing to sixth abdominal sternite. Antennae, 
first segment, length 1.16, tapering to be- 
come more slender on apical half, chiefly 
white, black on anterior aspect, with only 
one or two small, pallid spots cutting into 
edge of dark color, setae short, brownish; 
second, 2.51, chiefly yellowish brown, black 
at apex and next to pallid basal annulus; 
third, 1.34, yellowish, fuscous apically; 
fourth, 0.73. Pronotum, length 0.88, width 
at base 1.60; pale yellowish to dusky; calli 
pallid; lower margin of propleura and area 
on coxal cleft whitish, a black ray crossing 
lower margin of coxal cleft and flaring out 
at basal margin; basal edge of disk white, 
bordered by four black points which are 
often connected by dark color. Dorsum 
clothed with pale to brownish, simple pubes- 
cence sparsely intermixed with more re- 
cumbent, silvery, silky pubescence. Scutel- 
lum usually pale yellowish, sometimes 
dusky; a small fuscous spot indicated on 
either margin at middle of apical half. Hem- 
elytra dusky gray, with an irregular black 
area on middle of claval vein and a subtri- 
angular one on inner apical angle of corium; 
embolium uniformly yellowish gray, except 
for darkened extreme tip; cuneus with apex 
and spot on inner margin, and spot on inner 
margin of paracuneus, fuscous to black. 
Membrane uniformly pale fuscous, scarcely 
paler near apex of cuneus; cubitus white 
around apex of areoles, fuscous where it 
separates areoles. Legs pale yellowish, 
tibiae without dark bands; spines yellowish 
to dark brown; hind pair with black micro- 
setae; femora dark brown to black, with 
numerous, minute, pallid spots; hind pair 
with two rather distinct pallid bands on 
apical half; tarsi fuscous to black. Venter 
almost white to yellowish; lateral line fus- 
cous; sides of genital segment fuscous. Geni- 
tal claspers distinctive for species, fig. 176. 
FEMALE.—Length 5.60, width 2.16. Head 
width 0.99, vertex 0.41. Antennae, first seg- 
ment, length 1.21; second, 2.73; third, 1.55; 
fourth, 1.38. Pronotum, length 0.95, width 
at base 1.64. Very similar to male in color 
and pubescence, but light areas perhaps 
more extensive. 
Hasits.—Breeds on switch cane (Arun- 
dinaria tecta) ; doubtless predacious.
