Key to the Species of the Genus Insara 



A. Subgenital plate of male with distinct articulate styles. Genicular 

 lobes of cephalic and median femora produced in a single dentiform proc- 

 ess bearing no small supplementary spine. (Cephalic tibiae with proxi- 

 mal extremity much swollen, narrowing sharply distad of tympanum.) 

 Tegmina obliquely truncate at apex. Dorsal abdominal segments strongly 

 acute-angulate produced mesad. 

 B. Tegmina narrow, distal width greater than mesal width. (General 

 color varying from ochraceous to seal brown, more or less marmorate 

 with darker browns; rarely suffused with green.) 

 C. Lateral carinae of dorsum of pronotum from narrowest point 

 gently concavo-divergent in the cephalic third, then as arcuately 

 divergent caudad without a distinct angulation. (Tegmina 

 reaching beyond distal extremities of caudal femora. Lateral 

 lobes of pronotum with length subequal to depth.) 



tolteca (Saussure) 

 CC. Lateral carinae of dorsum of pronotmn from narrowest point 

 distinctly convexo-divergent in the cephalic third, then arcuately 

 divergent caudad with a decided though obtuse angulation. 

 D. Size smaller. Tegmina usually not reaching distal extremi- 

 ties of caudal femora. Lateral lobes of pronotum with length 



slightly less than depth intermedia (Brunner) 



DD. Size larger. Tegmina reaching beyond distal extremities 

 of caudal femora. Lateral lobes of pronotum with length 

 often considerably less than depth. 



bolivari (Griffini) 

 BB. Tegmina very wide throughout; distal width subequal to mesal 

 width. (Lateral lobes of pronotum with length subequal to depth. 

 General color immaculate apple green.) 



prasina (Saussure and Pictet) 

 AA. Subgenital plate of male bearing non-articulate styliform appendages. 

 Genicular lobes of cephalic and median femora produced in a single 

 dentiform process bearing a small supplementary spine. Tegmina 

 rounded at apex, (proximal width the greatest). Dorsal abdominal 

 segments weakly acute-angulate produced mesad. 



B. Cephalic tibiae with proximal extremity much swollen, narrowing 

 sharply distad of tympanum. Structure very slender. General 

 color varying from ochraceous to seal brown, more or less marmor- 

 rate with darker browns. 



C. Structure showing extreme attenuation. Lateral lobes of 

 pronotum with length much greater than depth.
