d'^. Tegmina fully developed or abbreviate, never much 

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

 notuni distinctly angulate ; fore and middle femora scarcely 

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

 some species of Campylacantha) . 



e^ 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. ILjpocldora Brunner. 

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

 tudinally ; prosternal spine more or less retrorse ; fm-- 

 cula of male reduced to slight scarcely projecting lobes ; 

 surface of the body rather densely pilose. 



Campylacantha Scudder. 

 A ^. 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 entii'e margin rather strongly convex or sinuate. 

 6^ 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^ b'^). 



c \ 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 ^. Median carina of pronotum feebly develojied 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. 



c?\ Body relatively slender and compressed, not much 

 enlarged at the metathorax, particularly in the male ; disk
