-248 The Ohio Naturalist. [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 sfmilar to co/on, twice as long as the penulti- 

 mate, the lateral angles acute, posterior margin slightly, angularly emargi- 

 nate, the di.sc elevated so as to appear still more deeply notched. This 

 emargination 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 BAIvL. 



Atliysanus le.ratiiis 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.
