under side bright yellow; rostrum black, reaching almost to the posterior 
coxae; antennae black at base. Pronotum banded on the anterior margin 
by a slender black line, and with five straighten and more slender lines 
which stop just short of the lateral margins, these lines feebly impressed 
and obsoletely, minutely scabrous, surface not wrinkled, almost smooth, 
moderately convex, deeply emarginated behind, the lateral margin nar- 
rowly produced as far as the outer line of the eyes; the humeral margin 
recurved, and with a small black dot before it. Scutellum pubescent, yel- 
low, transversely wrinkled, with a slender black line at base, and an inter- 
rupted one behind the middle. Hemelytra with short, remote, golden 
pubescence, coarsely punctate at base, more obsoletely so posteriorly; the 
inner and posterior margins, the suture between the corium and clavus, an 
oblique short streak on the disc, and a spot on the middle of the costa fus- 
cous: posterior margin of the corium with a sinuous brown band, the mem- 
brane and posterior one-third of the corium, and spot at base of costa pale 
brown; the bulla very prominent, black; under side yellow; the mesoste- 
thium, discs of the plural pieces, and middle line of genital segment pitch 
black Legs, yellow, the tibiae having a band below the knee, another on 
the middle, and a third at tip, and the spines of tibiae and tarsi, including 
the nails, dark piceous. 
Length to the tip of hemelytra, four and one-half mm., width of prono- 
tum, two mm. 
After a careful study of representatives from every state 
from which it has been reported so far, the following descrip- 
tion, embracing only characters of specific value was prepared. 
Size variable; color from yellow to black; front much inflated; two cir- 
cular yellow depressions on vertex near eyes; pronotum strongly, broadly 
wrinkled. 
Front rising abruptly from face at sides, meeting vertex in same plane 
above, outline a regular curve. Vertex very slightly transversely 
depressed; a distinct, circular, yellow depression midway between eye and 
ocellus on either side. Pronotum coarsely pubescent, strongly, transversely, 
wrinkled, about eight on the median line. Hemelytra coarsely pubescent; 
veins on clavus strongly raised; apical cells transversely compressed, third 
cell triangular, not reaching beyond angle of posterior marginal vein. 
Legs stout; spurs and spines strong; femur and tibia with dark lateral 
lines coalescing with two dark spots on outside of tibia. 
Sub. sp. I. lineata. Pronotum yellow, with five black bands. 
Var. a, Clavus with veins and margin yellow inclosing dark areas. 
b. Clavus entirely fuscous. 
Sub. sp. II. binotata. Pronotum entirely black. 
Habitat: Utah (Uhl), Cal. Col. and Ariz. 
This species is so widely variable that with only the extreme 
forms there would be no hesitancy in pronouncing them sepa- 
rate species, but with a large amount of material a series can 
be found which clearly establishes their relationship. Uhler’s 
description is an absolutelyperfect one for Sub. sp. lineata var.
