197 



g^. Prosterual spine erect ; interepace between mesosternal 

 lobes of male nearly twice as long as broad; fore and 

 middle femora of male noticeably gibbous; subgeuital 

 plate of male terminating in a large conical tubercle. 



Barytettix. 



g^. Prosternal spine retrorse ; interspace between meso- 

 sternal lobes of male only a little longer than broad ; fore 

 and middle femora of male only slightly gibbous ; subgeni- 

 tal plate of male with no apical tubercle. . Phaulotettix. 

 f. Last dorsal segment of male entirely without projecting 

 lobes or furcula in any form, unless as exceptionally broad 

 and short sessile plates ; cerci of male (except in Cepha- 

 lotettix) apically acuminate or curved upwards. 



g^. Head large, and eyes, at least in male, large and very 

 prominent, the breadth of the head distinctly exceeding 

 the greatest width of the pronotum ; interspace between 

 mesosternal lobes of male slightly transverse. 



Cefhalotettix. 



g^. Head normal and eyes not very prominent even in the 

 male, so that the breadth of the head does not exceed 

 the greatest width of the pronotum ; interspace between 

 mesosternal lobes of male distinctly longer than broad. 

 h^. Tegmina lobiform ; subgenital plate of male pro- 

 truding beyond the tip of the supraanal plate by less 

 than half the length of the latter ; cerci of male com- 

 pressed, subequal, the tip broad . . • . Rhabdotettix. 



K^. Tegmina linear ; subgeuital plate of male protruding 

 beyond the tip of the supraanal plate by much more 

 than half the length of the latter ; cerci of male taper- 

 ing from the base, the tip acuminate . . Cyclocercus. 



e^, Furcula of male consisting of a pair of parallel, attingent, 

 cylindrical processes, generally at least twice as long as broad. 



/\ Tegmina lobiform ; interspace between mesosternal lobes 

 of male slightly transverse ; cerci of male forming compressed 

 subequal laminae Sinaloa. 



f^. Tegmina wanting ; interspace between mesosternal lobes 

 of male longer than broad ; cerci of male styliform, conical. 



Paraidemona.
