cate; lateral lobes with ventral margin moderately oblique, declivent 

 cephalad with ventro-cephalic angle more broadly rounded than ventro- 

 caudal angle, which is distinctly more ample, weakly obtuse-angulate. 



Tegmina much less ample than in camellifolia, 

 with veinlets more regular and pronounced, 

 stridulating area much as in that species. Wings 

 almost as long as tegmina, by which they are 

 wholly concealed. Limbs and armament of same 

 as in camellifolia. Supra-anal plate somewhat 

 longer than broad, sulcate meso-proximad, be- 

 yond this portion moderately expanding, with 

 distal margin subtruncate and moderately ser- 

 rate. Cerci evenly rounded at base, then forking 

 at a distance equal to the basal width and pro- 

 duced in two very slender and little divergent 

 spines which have an even inward curvature, 

 the outer spine nearly twice as long as the inner 

 (dorsal) spine. Subgenital plate nearly as long 

 as the caudal femur; the heavy margins of the 

 produced shaft forming a broad, deep mesal 

 groove both dorsad and ventrad ; apical portion 

 split, with the two parts distinct but attingent

Similar to the type, but larger. Supra-anal plate longer than broad, 

 distal margin rotundato-truncate. Cerci long, nearly straight, termi- 

 nating in a sharp tooth. Ovipositor similar to that of camellifolia. 

 Subgenital plate nearly divided mesad into two very narrow apd trans- 

 verse lateral lobes, leaving the base of the ovipositor exposed.
