Elongate-oval, pale green, bald, and polished. Apex of the head 

 tumidly conical ; cranium minutely, obsoletely jmnctate on the sides ; 

 the cranial shield triangular in front, so caused by the converging of the 

 lateral carinpe ; central carina high and thick, the lateral ones very high 

 and divaricating anteriorly 5 the front oblique, depressed, banded twice 

 with orange or rufous; the pair of central carinse high, curving apart, 

 abbreviated before the epistoma ; the e])istoma piceous or rulb-piceous at 

 base ; rostrum yellowish, piceous at tip, reaching to the tip of the inter- 

 mediate coxae. Eyes large, horizontal, subreniform, pale brown ; anten- 

 npe greenish ; the scapus and basal joint subequal, the former with a 

 I)road black line, the latter wdth two black lines and an anterior ring; 

 second joint longer than the two former, with two black lines. Prono- 

 tum short, truncate in front, sinuate on the posterior margin, the cen- 

 tral line and an oblique one each side carinated, the lateral edge sinu- 

 ated to receive the tegulee; tegulse very minutely punctured. Meso- 

 sternum longer than the pronotum, with five carinated lines, the lateral 

 ones a little curved, and the apex slightly elevated. Legs green ; the 

 femora and tibse, excepting the posterior pair, lineated with black, and 

 ■with the tips of the spines, the nails, a broad band near the tip of the 

 anterior tibiae, and a large spot on each anterior coxa, black; hemelytra 

 long and narrow, obliquely rounded at tip, yellowish-green, the nervures 

 straight and wide apart, with only two or three cross-nervules near the 

 tip ; the radial nervure forked at the middle, the first and second ulnars 

 forked near the tip. Wings white; tergum sometimes infuscated on 

 the disks of the segments. Anus of the lemale armed with a long, acute 

 stylet; both sexes with a few long bristles at the apex of the venter; 

 hemelytra of the male with five longitudinal cells at the apex; the infe- 

 rior genital segment divided into two (;urved, very acute, piceous hooks, 

 and the anus with a still longer stylet than in the other sex. 



Length to tip of hemelytra, 5 to 8^ millimeters. Width of pronotum, 

 1^ to 2 millimeters. 



Inhabits Dakota, collected by Mr. Eothauer; Illinois, Eobert Ken- 

 nicott. It also occurs abundantly upon the salt-marshes of the sea- 

 coasts of Maryland and New Jersey, living among the long, stiff grass. 

 When fresh and not weather-beaten, it is of a vivid light green, but 

 "when old and weathered it becomes soiled yellow in color. It would be 

 interesting to know if this species belongs to places in the West which 

 were originally the beds of salt-lakes. The salt-marshes of Eastern 

 Massachusetts have thus far failed to yield any specimens of it.
