in the middle posteriorly. Elytra rather broad, venation distinct, 

 similar to that ot^ floridana ; female less reticulate. 



Color; vertex and face pale yellow, finely irrorate with brown, 

 the frontal sutures including the ocelli, a basal median line and an 

 irregular wedge on anterior half, fuscous. Pronotum olive gray- 

 ish, a row of submarginal creamy spots sometimes extending back 

 onto the disc as pale lines. Scutellum pale impressed line, spots 

 inside basal angles and a pair on anterior disc, dark. Elytra cin- 

 ereous or sometimes greenish, nervures pale. The male sometimes 

 darkened up to a slaty brown. Below pale, margins of abdomen 

 often red. 



Genitalia; female segment half longer than the penultimate, pos- 

 terior margin nearly truncate, a somewhat variable obtuse, median 

 tooth. Male valve almost concealed, plates stout, coriaceous, 

 scarcely longer than the ultimate segment, their apices bluntly 

 pointed, upturned, whole genitalia reddish. 



Described from eighteen specimens from La Salle and 

 Fort Collins, Col. The first specimens were collected by 

 Professor Gillette.

Small, moderately stont, vertex blunt, shorter than 

 pronotum. Elytra densely reticulated before the apex. 

 Green with the head pale, washed with reddish. Length, 

 9 5.5 mm., s 4-5 mm. 



Vertex bluntly conical, nearly right angled, two-thirds the 

 length of the pronotum, ocelli large. Face in profile convex. The 

 clypeus slightly elevated, front broad rounding with the vertex. 

 Pronotum rather long, strongly emarginate on the median third 

 posteriorly. Elytra as xu^mollipes, but with the reticulations more 

 numerous, much more numerous than in the two preceding species. 



Color; vertex and face pale, finely irrorate with brown and 

 washed with reddish orange, a pair of spots against the ocelli on 

 the inside and a marginal line sometimes emphasized in the spots 

 at the apex, creamj-; ocelli shining black; anterior margin of pro- 

 notum and the scutellum pale yellow; disc of pronotum and elytra 

 green or grayish green; nervures and margin pale, distinct. Legs 

 and below pale yellow, margins of the abdominal sternites in the 

 female reddish. 



Genitalia; female segment half longer than the penultimate, pos- 

 terior margin truncate, the median half roundingly produced. Male 

 valve short, nearly as wide as the plates at base, plates long, 

 acutely triangular, slightly longer than the ultimate segment.
