fourth, distal fourth of costal margin curving to the rather narrow and blunt 

 apex, which latter is sutural in position; discoidal rami three in number, the 

 proximal one diverging but a short distance distad of the middle of the vein; 

 stridulating field with the stridulating vein strongly oblique, arcuate proxi- 

 mad to base of tegmen, speculum longitudinal, the greatest width contained 

 one and one-half times in the greatest length of the same, apex of speculum 

 acute, sutural margin of stridulating field broadly arcuate proximad of the 

 apex of the stridulating vein, then briefly sinuato-emarginate distad and 

 finally oblique subtruncate to the major portion of the sutural margin. 

 Wings surpassing the tegmina by slightly more than half the length of the 

 latter; greatest depth of wings in repose subequal to the greatest depth of 

 tegmina, apex of wings moderately acute. Dorsum of the abdomen with no 

 proximal erect process; margins of the dorsal segments multicrenulate, the 

 points of the crenulations being formed by minute thickened callous nodes; 

 disto-dorsal abdominal segment with margin entire, truncate; supra-anal 

 plate transverse arcuate; cerci moderately robust, tapering, slightly de- 

 pressed, nearly straight, distal fourth bent inwards at a right angle, the tips 

 aciculate; subgenital plate elongate, subcompressed, tricarinate ventrad, 

 the median carina more decided and elevated than the lateral ones, distal 

 margin deeply subtriangularly emarginate, the emargination sinuate 

 laterad, brief substyliform processes present laterad of the emargination. 

 Limbs very elongate. Cephalic and median femora with the supragenicular 

 portion of the extremity subcompressed, blunt angulate, not at all produced 

 or spiniform; genicular lobes of the same limbs bispinose, of the caudal 

 femora unispinose. Cephalic femora slightly less than twice the length of 

 the head and pronotum; cephalic tibiae w^ith tympanum elliptical. Median 

 femora nearly one and one-half times the length of the cephalic femora. 

 Caudal femora slightly less than twice the length of the body, little inflated 

 proximad; caudal tibiae exceeding the femora by about the length of the 

 head and pronotum. 



Allotype. — 9 ; Data same as type. 



Description of Allotype. — The following characters are chiefly those of 

 difference from the male sex. Head and pronotum as in the male. Tegmina 

 subequal to the body (exclusive of ovipositor) in length, at proximal third 

 not narrower than at distal fourth; discoidal rami four in number, the 

 proximal one diverging mesad. Wings as in male. Disto-dorsal abdominal 

 segment with margin entire, arcuato-truncate; supra-anal plate semiellip- 

 tico-trigonal, the proximal half and the adjacent distal half of the disto- 

 dorsal abdominal segment with a deeply impressed medio-longitudinal 

 sulcus; cerci moderately elongate, terete; ovipositor robust very short, 

 sharply curved, greatest depth distinctly greater than half the length of the 

 same, dorsal margin with the distal half moderately serrato-dentate, the 

 size of the serrations increasing distad, distal third of the ventral margin 

 with recurved serrato-dentations, the median third fineh' crenulate, the 

 proximal third straight and smooth, surface of the distal third of the ovi- 

 positor with series of sharp ridge-like teeth arranged in linear fashions, there 

 being about six series on the dorsal valves, the ventral series of whicli has
