ORTHOPTEROUS GROUP INSARAE 



junction of the two valves; subgenital plate acute-trigonal, elevated and 

 bicarinate mesad. Limbs very slender and elongate; cephalic and median 

 femora with the dorsal margin of the distal extremity compressed and pro- 

 duced into a triangular point or spiniform process, all genicular lobes of the 

 same limbs bispinose. Cephalic femora over two and a half times as long 

 as the disk of the pronotum; cephalic tibiae with an elliptical tympanum. 

 Median femora about half again as long as the cephalic femora. Caudal 

 femora nearly twice the length of the median femora, little inflated proxi- 

 mad, genicular lobes unispinose; caudal tibiae surpassing the femora by 

 about the pronotal length. 



Description of Male: Thomasville, Thomas County, Georgia, June 29, 

 1903, (Collected for Hebard), [Hebard Collection]. The following char- 

 acters are those of difference from the female sex. Head and pronotum as 

 in the female but with a very weak and fine medio-longitudinal ridge on the 

 dorsum of the pronotum. Tegmina with the form as a whole as in the fe- 

 male, but in length half again as long as the body and with the discoidal vein 

 bearing five rami on each tegmen; stridulating field appreciably shorter 

 than the dorsum of the pronotum, its greatest width about two-thirds its 

 greatest length, stridulating vein heavy, oblique, subarcuate, margin of 

 field but little produced at the apex of the stridulating vein, there rotundato- 

 rectangulate, sinuate distad of the same, speculum crudely quadrate. 

 Wings projecting distad of the tegmen slightly more than a third the length 

 of the latter. Disto-dorsal abdominal segment having the distal margin 

 subarcuate with a faint median truncate section; supra-anal plate slightly 

 transverse, subrectangulate in general form but with the margins and angles 

 rounded; cerci tapering, with the distal fourth rather sharply bent inwards, 

 subdepressed in the same section, apex acute; subgenital plate elongate, 

 narrowing distad, ventral surface with five carinae distad, one mesad (this 

 extending greatly proximad) and two closely placed pairs laterad, distal 

 extremity with brief substyliform processes, between which the margin is 

 arcuato-truncate. Limbs as in the female.
