BB. Dorsum of pronotum dark. Distal portion of abdomen 

 enlarged. 

 C. Distal portion of abdomen slightly enlarged. (Fereula 

 present; small, broad, blmit, trigonal. Cerci moderately 

 elongate, slender, tapering to acute apex. Supra-anal 

 plate trigono-shield-shaped, with a minute dorsal tubercle 

 proximad on each side. Subgenital plate simple, small, 



scoop-shaped) gracilis (Bruner). 



CC. Distal portion of abdomen decidedly enlarged. 



D. Fereula absent. Cerci decidedly elongate, very slender 

 in distal portion but with apex blunt. Supra-anal 

 plate short, trigono-shield-shaped. Subgenital plate 

 simple, small, scoop-shaped. Pronotum with decided 



dorso-lateral pale lines histrigata (Scudder). 



DD. Fereula represented by weak and broad convexities of 



the segment. Cerci and subgenital plate specialized. 



Supra-anal plate elongate, shield-shaped. Pronotum 



without decided dorso-lateral pale lines. 



E. Supra-anal plate elongate shield-shaped, truncate 



obtuse-angulate distad, with a minute dorsal tubercle 



proximad on each side. Cerci moderately elongate, 



distal portion moderately broad, tapering sharply at 



extremity to acute ventral apex. Subgenital plate 



small, produced in a small median, marginal, blunt 



tubercle angustipennis Scudder. 



EE. Supra-anal plate elongate shield-shaped, lateral margins 

 cingulate, straight and convergent proximad, convex 

 ancl convergent distad. Cerci heavy, elongate, with 

 an acute proximal projection on ventral margin," 

 distal portion moderately broad, curving ventrad, 

 with margins at extremity weakly convex to the 

 acute apex. Subgenital plate large, the free margin 

 above the plane of the supra-anal plate, with a large, 

 very blunt, median, marginal tubercle feebly sug- 

 gested valga (Scudder). 



AA. Tegmina longer, elongate ovate. Supra-anal plate simple, 

 broadly shield-shaped. .Cerci broad. 

 B. Cerci broad, not bent inward, apex acute and situated dorsad, 

 distal margin strongly oblique. Fereula minute, bluntly 

 obtuse-angulate projections. General coloration green, 

 locally washed with red, color pattern not complex. (Sub- 

 genital plate small, simple, with distal portion the more 



strongly rounded but not tuberculate) litus new species. 



BB. Cerci bent inward at near the middle, apex evenly rounded. 

 Fereula very broad and extremely narrow plates with 

 distal margin straight. General coloration brown to green, 

 not washed with red, color pattern complex. (Pallium 

 conical, produced.) 



" This frequently projects downward between the supra-anal and subgenital 

 plates and is in this position concealed.
