very short and lost in the general vein structure of the costal field, the 

 trend of the principal veins of which is ventro-caudal ; median vein 

 diverging before the distal third of the tegmen and reaching the 

 apical margin; ulnar vein rather irregular and indirect in its course. 

 Male with the last abdominal segment transverse, margin subtruncate

with a strong incurved hook present on each side; supra-anal plate 

 subquadrate excavated mesad, caudal margin with a broad median 

 and two slender lateral acute processes ; cerci short, thick, blunt, re- 

 curved, the internal margin of the apex with a strong claw-like tooth; 

 subgenital plate longitudinal, produced, the apical 

 margin with a V-shaped emargination, styles slightly 

 longer than the plate, depressed, subequal, tips 

 rather blunt. Ovipositor about two and a half times 

 the length of the pronotum, slightly sinuate, the tip 

 with a slight dorsal elevation, the proximal half sub- 

 equal, the distal half tapering to the very acute apex, 

 ventral margin slightly arcuate, dorsal margin ex- 

 cept for the proximal third and a short space near 

 the apex dentato-serrate, ventral margin feebly ser- 

 rate near the apex; subgenital plate trigonal with a 

 narrow V-shaped median emargination. Cephalic 

 femora about equal to the head and pronotum in 

 length, the ventro-cephalic margin with four heavy 

 dentiform spines distad; cephalic tibiae very slightly 

 longer than the femora, unarmed dorsad; each ven- 

 tral margin armed with seven spines; tarsi with the third joint very 

 broad, the entire length nearly two-thirds that of the tarsi, Me-
