half as broad as at base, the apical lobe single ; 



furcula developed as mere denticulations 



ampleciens. 

 g^. Cerci of male at most gently if at all incurved, and 

 feebly if at all enlarged apically, 



h}-. Metasternal lobes of male subattingent ; tegmina 

 shorter than the pronotum ; anal cerci of male 

 straight as seen laterally, or slightly upcurved api- 

 cally. 



/\ Cerci of male rounded at tip ; furcula scarcely 

 protruding beyond the hind margin of the last 

 dorsal segment ; apical margin of the subgenital 

 plate slightly elevated above the lateral margins. 

 y\ Supraanal plate of male suddenly con-

 incurved throughout ; subgenital plate very 



broad at base saltator. 



y\ Supraanal plate of male regularly triangu-

rotundipennis, 

 P. Cerci of male truncate at tip; lobes of furcula 

 long; apical margin of subgenital plate in no

obovatipennis. 

 h^. Metasternal lobes of male only approximate ; 

 tegmina as long as or much longer than the prono-

 or at least inferiorly angulate at apex. 



P. Tegmina not much longer than the pro- 

 notum ; cerci of male delicate, tapering con-

P. Tegmina more than half as long as the ab-
