times transverse, sometimes quadrate or subquadrate ; teg- 

 mina lobiform, linear, or wanting. 



d^. Apical tubercle of subgenital plate small, extending 

 but a short distance beyond the supraanal plate ; cerci of 

 male abruptly narrowed before the middle by excision of 

 the inferior margin, the apical half narrow ; lateral carinae 

 of pronotum wholly wanting. Phaedrotettix Scudder. 



d'^. Nearly the whole subgenital plate forming a blunt 

 conical tubercle pi-ojecting some distance beyond the 

 supraanal plate ; cerci of male forming broad, apically 

 decurved, subfalcate laminae ; lateral carinae of pronotum 

 more or less distinct. . . Conalcaea Scudder. 



c . Interspace between mesosternal lobes of female gener- 

 ally longer than broad, sometimes quadrate, rarely feebly 

 transverse ; of male never at all transverse ; tegmina 

 variable. 



d^. Tegmina never fully developed, rarely as long as the 

 pronotum, lateral and ovate or linear, or wholly wanting ; 

 hind margin of pronotum distinctly truncate ; fore and 

 middle femora of male distinctly more gibbous than in the 

 female. 



e ^ Furcula of male wanting, or forming a pair of 

 brief lobes, at most no longer than broad. 

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

 truding beyond the tv^ of the supraanal plate by less 

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

 pressed, subequal, the tip broad. 



Rhahdotettix Scudder. 

 f'^. Tegmina linear; subgenital plate of male pro- 

 triiding beyond the tip of the supraanal plate by 

 much more than half the length of the latter; cerci 

 of male tapering from the base, the tip acuminate. 



Cydocercus Scudder. 

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

 attingent, cylindrical j^rocesses, generally at least twice 

 as long as broad. . . Paraidemona Brunner.
