[Vol. II, No. 6, 
Color : dirty straw, marked with rusty brown and olive ; vertex with a 
shining black spot either side at the apex, extending equally on to the front, 
a pair of small, round spots midway to the ocelli just back of the margin and 
two pairs of widely separated, quadrate, rusty brown spots on the disc. 
Pronotum with six more or less irregular, brownish stripes ; scutellum with 
a pair of large spots at base and a pair of dots on disc. Elytra with the 
nervures broadly pale, narrowly margined with rusty brown in irregular 
bands ; usually a rather distinct, oblique one from before the middle of 
clavus to the outer apical margin. Abdomen above with four longitudinal 
stripes emphasized on their margins ; pygofers with a pair of black spots, 
larger in the male. Face pale, the sutures dark-lined and distinct, front 
irrorate or lined with olive fuscous ; legs pale, anterior and middle femora 
twice annulate, posterior femora lined with brown. 
Genitalia : female segment similar to colon , twice as long as the penulti- 
mate, the lateral angles acute, posterior margin slightly, angularly emargi- 
nate, the disc elevated so as to appear still more deeply notched. This 
einargination discloses a pointed lobe of another membrane which nearly 
equals the lateral angles ; pygofers short and stout ; male genitalia as in 
comma and in colon. 
Habitat : Colorado, where it is fairly common, locally, in the 
short-winged form. No long-winged specimens have been found. 
ATHYSANUS TEXANUS OSB. AND BALL. 
Athysaniis texanus Osb. and Ball. Proc. Dav. Acad. Nat. Sc.. VII. p. 92, 1898. 
Form elongate, parallel-margined ; vertex flat, less angled than in comma, 
anterior margin sharp. Color pale yellow, a pair of broad, parallel, red 
stripes extending from the anterior margin of vertex across the scutellum 
and three pairs of oblique ones on the elytra ; face dark. Length, 9 5 mm.; 
width, 1.75 mm. 
Vertex flat, but a trifle longer on middle than at eye, narrower than in 
comma, a transverse depression just before the sharp anterior margin ; face 
in profile sharply angled with vertex, in one broad, slight curve to apex of 
■clypeus ; front moderately broad, its margin at base approaching the eye, 
gradually narrowing to the straight clypeus, but slightly transversely con- 
vex. Pronotum strongly produced anteriorly between the eyes. Elytra 
long and narrow, venation distinct towards apex, somewhat similar to colon 
in pattern, the outer anteapical cell closed, long and curved, central ante- 
apical long, constricted, sometimes divided. 
Color : pale yellow above, a narrow line on anterior margin of vertex, a 
small spot either side of the tip, a curved mark on the costal margin of 
elytra behind the middle, a spot on second apical and the posterior margin 
of the central anteapical cell, black ; two broad stripes parallel across vertex, 
pronotum and scutellum and three pairs on the elytra parallel with the 
claval suture, the inner pair continuous with those from the scutellum, bright 
red. Face dark brown, shining.
