d 2 . Tegmina fully developed or abbreviate, never much 

 if any shorter than the pronotum ; hind margin of pro- 

 notum distinctly angulate ; fore and middle femora scarcely 

 more gibbous in the male than in the female (except in 

 some species of Campylacantha) . 



e 1 . Head not prominent, the summit very slightly 

 arched longitudinally ; prosternal spine erect ; furcula 

 of male composed of projecting cylindrical fingers ; sur- 

 face of body very feebly pilose. Ilypochlora Brunner. 

 e 2 . Head prominent, the summit strongly arched longi- 

 tudinally ; prosternal spine more or less retrorse ; fur- 

 cula of male reduced to slight scarcely projecting lobes ; 

 surface of the body rather densely pilose. 



Campylacantha Scudder. 



A 2 . Lateral margins of subgenital plate of male suddenly ampliate 

 to a considerable degree at the base ; or if not to a considerable 

 degree, then the entire margin rather strongly convex or sinuate. 

 6 1 . Subgenital plate of male furnished with a distinct sub- 

 apical tubercle (i. e., one in which the apical margin does not 

 pass through and form a part of the summit of the tubercle, 

 but where it is distinctly separated from the summit) , but not 

 otherwise tumescent (see note under A 2 b 2 ) . 



c l . Median carina of pronotum well developed and equally 

 developed throughout, accompanied on the front of the pro- 

 zona by distinct lateral carinae ; prosternal spine sharply 

 acuminate ; tubercle of subgenital plate directed wholly 

 backward, occupying the middle of the terminal portion of 

 the plate ; furcula distinctly developed. Eotettix Scudder. 

 c 2 . Median carina of pronotum feebly developed and gener- 

 ally much more feebly on the prozona than on the metazona, 

 accompanied by no lateral carinae whatever ; prosternal 

 spine bluntly acuminate ; tubercle of subgenital plate directed 

 upward, or upward and backward, occupying the upper 

 extremity of the terminal portion of the plate. 



d l . Body relatively slender and compressed, not much 

 enlarged at the metathorax, particularly in the male ; disk
