of cercus distinctly shorter than that portion of shaft behind 

 it, its apical half straight or nearly so (Figs. 179, 180, e.) 

 g. Outer carina of hind femur in both sexes armed on apical 

 third with two to eight stout spines; form slender; teg- 

 mina in female scarcely reaching the tip of ovipositor. 



249. PULCIIELLUM. 



gg. Outer carina of hind femur unarmed in male, with one or 

 two minute spines on apical third, female; form much 

 stouter; tegmina of female distinctly surpassing the tip of 

 ovipositor. 250 BULLATUM. 



ff. Humeral sinus almost obsolete; tibiae all blackish; notch of 

 supra-anal plate V-shaped, deeper than broad; tooth of cer- 

 cus almost as long as the portion behind it, distinctly inclined 

 toward base of cercus, its apical half curved (Figs. 179, 180, 

 f ) ; tegmina but feebly if at all surpassing hind femora.

act. Tooth of male cercus distinctly longer than apical portion of shaft 

 and strongly aciculate (Fig. 179, g) ; humeral sinus scarcely evi- 

 dent (Fig. 182, c) ; outer lower carina of hind femora always spined.

245. OBCHELIJIUM AGILE (DeGeer), 1773, 457. Agile Meadow Grass-hopper 



Size medium for the genus; form moderately robust. Color variable; 

 usually dull reddish-brown, with lateral lobes of pronotum, costal or lower 

 edge of tegmina, tibiae and apical half of hind femora green or with a green- 

 ish tinge, sometimes nearly uniform pale green with dorsal surface tinged 

 with clay yellow; pronotum often with a pair of dark brown diverging 

 stripes. Fastigium broader at apex than at base, the former rounded and 

 with a fine median line above. Antenna? twice or more as long as body. 

 Disk of pronotum short; lateral lobes with lower margin oblique, its hind 

 angle obtuse; humeral sinus broad, shallow'. Tegmina surpassing hind 

 femora about 3 mm., exceeded by wings about 2 mm. Outer lower carina 

 of hind femora with one to five spines. Cerci of male and ovipositor as 

 in key and Figs. 179, 180. Apex of subgenital plate of male subtruncate 

 or very feebly and broadly emarginate. Length of body, $ and 9 , 21.5 

 22.5; of pronotum, $ , 5, 9, 55.6; of tegmina, $, 23.5 24.5, 9, 2525.7;
