near the distal third of the tegmen; anterior iihiar vein reaching the 

 su+ural margin a short distance distad of the furcation of the radial 

 vein. Wings extending beyond the closed tegmina, a distance about 

 equal to the length of the pronotum. Ovipositor about twice the 

 length of the pronotum, saber-like in form, the greatest width slightly 

 less than a third the length and in the distal half, apex acute, dorsal 

 margin straight with a slight proximal curve, ventral margin almost 

 straight in the proximal half, strongly arcuate in the distal half, mar- 

 gins of the distal half crenulato-dentate; subgenital plate very deeply 

 and triangularly emarginate, the base of the emargination rounded, 

 lateral processes of the plate produced slender and digitiform. Cephalic 

 tibiae moderately rounded and unarmed dorsad. Caudal femur reach- 

 ing to the apex of the ovipositor, slender in the distal half. 



General color apple green, the head and thorax soiled olive-yellow; 

 abdomen pale orange-buff; sutural margins of the tegmina naples 

 yellow; margins of the tip of the ovipositor vandyke brown; eyes mars 

 brown. 



Measurements. 



Length of body, 16 mm. 



Length of pronotum, 4.5 



Length of tegmen, 27.5 



Breadth of tegmen, 6.2 



Length of caudal femur, 15.8 



Length of ovipositor, 9 



The specific name refers to the appendages of the subgenital plate. 



In addition to the type, a badly damaged male individual from 

 Esparta (altitude 50 meters; no. 45; P. Biolley) is referred with some 

 doubt to this species. The tegmina are somewhat slenderer than in the 

 type, but the venation is similar, while the head and pronotum, as well 

 as the sternal lobes, are identical. Subgenital plate and supra-anal 

 plate are as in A. lanceolata Brunner, the cerci however differ in being 

 without a basal lobule and having a spiral twist instead of being 

 straight and lanceolate.
