occiput with a hardly perceptible elevation; vertex sloping very 

 slightly toward the fastigiimi; interocular space almost twice as wide 

 as the frontal costa in the male and about once and a half the width 

 in the female; fastigium moderately produced, rectangulate, with a 

 distinct semicircular excavation, margins distinctly elevated, no me- 

 dian carina present; face distinctly retreating; frontal costa slightly 

 and gradually expanding, reaching to the clypeus, sulcate through the 

 entire length; eyes ovoid, in the male very decidedly longer than in 

 infra-ocular portion of the genae, in the female slightly longer than the 

 same ; antennae distinctly longer ( c? ) or considerably shorter ( 9 ) than 

 the head and pronotum. Pronotum subequal in the male, slightly 

 expanding caudad in the female, lateral carinse very slightly constricted 

 mesad; medium carina as distinct as the lateral; cephahc margin 

 rotund ato-trunc ate, caudal margin very broadly obtuse-angulate, 

 more rounded in the male than in the female ; transverse sulcus sever- 

 ing the median carina distinctly behind the middle ; lateral lobes of the 

 pronotum with the ventral margin very broadly obtuse-angulate. 

 Tegmina falling slightly short of the apex of the abdomen, apex slightly 

 narrowed and rotundato-truncate ; costal area with the proximal lobe 

 very prominent, ulnar area of the male with about eight distinct trans- 

 verse veins. Abdomen with the subgenital plate of the male produced 

 into a distinct tubercle; cerci straight, simple, tapering. Cephalic 

 and median femora of the male somewhat inflated. Caudal femora 

 exceeding the apex of the abdomen by nearly the length of the head, 

 moderately robust, distal portion slender with the genicular region 

 enlarged; tibise with thirteen or fourteen spines on the lateral margin 

 in the male and sixteen in the female. 



Male above apple green; sides and limbs cinnamon, shading to wood 

 brown on the lower surface, eyes and a distinct brownish-black post- 

 ocular streak which also suffuses the base of the tegmina; tegmina 

 (except for the green anal area) pale drab; antennae cinnamon, 

 slightly infuscate apically; dorsal carina of the lateral face of the 

 caudal femora olive ; lateral carinae of the pronotum narrowly lined 

 with cinnamon. 



Female with the sides, face and limbs apple green; postocular streak 

 as in the male ; head above centrally apple green, flanked by bars of 

 vinaceous-ruf ous ; pronotum above vinaceous-rufous; tegmina with 

 the costal area apple green, the continuations of the postocular streak 

 (reaching to the apex of the tegmina and including the whole discoidal 

 field) brownish-black, angle of the anal vein and adjoining portion of
