about twice in the dorsal length of the same, cephalic margin of lobes 

 straight, ventro-cephalic angles narrowly rotundato-subrectangulate,. 

 ventral margin very slightly oblique, sinuato-truncate, ventro-caudal 

 angle roundly obtuse-angulate, caudal margin obliquely arcuato- 

 truncate, the dorsal portion of the margin passing into the arcuation 

 of the caudal margin of the disk. Tegmina over three-fourths the 

 length of the disk, the greatest width of the discoidal and anal fields 

 little inferior to the tegininal length; costal margins moderately 

 arcuate, rounding into the slightly oblique subtruncate distal margin, 

 sutural margin subrectangulate, the angle at the extremity of the 

 stridulating vein broadly rounded, the distal section of the 

 same margin slightly sinuate; marginal field narrow, discoidal field 

 regularly expanding distad, anal vein arcuate, anal field with its 

 greatest length subequal to its greatest width, stridulating vein 

 decidedly arcuate, tympanum proper poorly developed. Disto-

dorsal abdominal segment with the margin truncate distad; supra- 

 anal plate trigonal, acute, the lateral margins of same slightly arcuate; 

 cerci with the proximal portion moderately robust, slightly flattened 

 dorsad, median lobe placed on dorsal surface, depressed, broad, when 

 viewed from the dorsum the margin of the lobe is broadly rounded 

 on the external and bluntly angulate on the internal side, shaft 

 proper arcuate inwards from proxiinad of middle, tapering, acute, 

 subaciculate, slightly curved dorsad; subgenital plate with proximal 

 width slightly less than greatest length, moderately produced, distal 

 half with margins converging for the greater portion of their length, 

 then subparallel, distal margin rectangulate emarginate, the lateral 

 angles very faintly blunted, ventral surface weakly tricarinate distad. 

 Cephalic femora somewhat shorter than the combined length of the 

 head, pronotum and tegmina; foramina of cephalic tibiae elongate 

 elliptical. Median femora slightly exceeding the combined length 

 of head, pronotum, and tegmina. Caudal femora slightly more than
