ACRIDIIDAE ACRIDIINAE 45 



d l . Interspace between mesosternal lobes of male dis- 

 tinctly transverse, * as broad or nearly as broad as the 

 lobes themselves; of the female distinctly or strongly 

 transverse, fully as broad as or (and generally) broader 

 than the lobes ; metasternal lobes of male generally dis- 

 tinctly distant, occasionally approximate; of the female 

 generally more distant, the interspace in the latter gener- 

 ally as wide as or wider than the frontal costa ; tegmina 

 typically abbreviate. 



e 1 . Face almost vertical ; eyes small but prominent and 

 widely distant; pronotum constricted in the middle, 

 with deeply impressed transverse sulci, and the lateral 

 lobes not obliquely truncate apically in front ; distinct 

 lateral carinae. . . . Dendrotettix Riley. 

 e 2 . Face a little oblique ; eyes rather large, not very 

 prominent and not very distant ; pronotum not, or but 

 feebly, constricted in the middle, with generally feebly 

 impressed transverse sulci, and the lateral lobes obliquely 

 truncate apically on the anterior section. 



Podisma Latreille. 



d' 2 . Interspace between mesosternal lobes generally longer 

 or much longer than broad in the male, almost never in 

 the least broader than long even when the sides of the 

 interspace are posteriorly divergent ; generally quadrate 

 in the female, but more variable than in the other sex, 

 sometimes as narrow as there, more often subtrans verse, 

 occasionally in some brachypterous forms distinctly trans- 

 verse ; in both sexes always distinctly, generally much, 

 narrower than the lobes (except in the females of the cases 

 just cited, where they are barely narrower); metasternal 

 lobes of male generally attingent or subattingent, rarely 

 only approximate ; of the female less distant than in the 

 alternate category (A 2 b 2 'c l J 1 ), generally approximate, 

 or subapproximate, the interspace generally narrower than 

 the frontal costa ; typically the tegmina are completely 

 developed. 



* In many cases the interspace is truncate-cuneiform or broadly clepsydral, in 

 which cases the breadth is to be measured in the middle.
