row, moderately elongate, the margin very broadly obtuse-angulate 

 at the apex of the stridulating vein, the latter thick, depressed, 

 hardly arcuate. Wings surpassing the closed tegmina by about 

 two-thirds the length of the pronotal disk. Prosternum with a 

 broadly triangular figure: mesosternum with rounded obtuse-angu- 

 late lobes: metasternum with convergent, shallow, arcuate lobes. 

 Abdomen but little compressed, the dorsal surface rounded tectate: 

 disto-dorsal abdominal segment relatively short, subdepressed 

 dorsad, faintly declivent distad; distal margin sinuato-truncate 

 dorso-mesacl, lateral margins markedly bisinuate: cerci relatively 

 heavy, forked from the base, the rami strongly diverging, the dorsal 

 one erect, moderately inbowed or faintly inbent, tapering, the apices 

 acute spiniform, on the external and internal surfaces bearing three 

 longitudinal grooves, separated by distinct, sharp carinulae; ventral 

 ramus directed ventrad and slightly cephalad, when seen from the 

 caudal aspect directed slightly inwards toward the median hue of 

 the body, the ramus relatively thick, weakly channelled on the 

 internal face, the extremity somewhat thickened and rounded bul- 

 bous, with a blunt tooth on the internal face sUghtly proximad of 

 the extremity; at about the middle of the ventral ramus, on the 

 caudal face, there is present a slender, spiniform process, which is 

 nearly straight and is directed caudo-mesad: subgenital plate rela- 

 tively large, scoop-shaped, with a distinct, complete, median carina 

 and short lateral carinae on the distal section of the plate, the latter 

 carinae ending in very low, blunt tubercles, which form the lateral 

 angles of the distal margin of the plate; distal margin of the plate 

 not longer than two-thirds the length of the lateral margin of the 

 plate, faintly angulate emarginate; lateral margins of the plate 

 sinuato-arcuate. Cephalic femora more than five-sixths the length 

 of the pronotal disk; cephalic tibiae one-third longer than the cephahc 

 femora, very slender distad of the enlarged proximal section, audi- 

 tory foramina relatively large, elhptical on both faces. Median 

 Hmbs missing. Caudal femora but shghtly shorter than the body, 

 moderately slender, ventral margins spined distad, the external 

 with seven, the internal with five spines both genicular lobes with a 

 single spine; caudal tibiae surpassing the length of the femora by 

 about half the length of the pronotal disk, all margins continuously 

 spined, the dorsal ones more heavily so than the ventral ones. 



General color ranging from sayal-brown on the head, pronotum 

 and sides of the abdomen, to ochraceous-tawny on the dorsum of 

 the abdomen, and cinnamon-buff, the latter broadly washed with
