portion, instead of being there parallel as in phaneropteroides. 

 Pronotum with surface smooth, the lateral lobes very slightly 

 deeper than wide. Tegmina and wings fully developed. Tegmina 

 with costal margin of stridulating field convex, not produced at 

 stridulating vein; median vein with four oblique branches which 

 do not fork. Anal tergite hooded, produced to opposite proximal 

 portions of cochleate cereal apices, there truncate, the lateral 

 margins obliquely ascendant and broadly concave to that point. 

 Supra-anal plate concealed. Cerci cylindrical in slightly over 

 proximal* half, the remaining distal portion expanded into a de- 

 licate, vertical, lamellate plate, which is irregularly quadrate with 

 angles rounded, bearing mesad on its concave internal surface a 

 large erect tooth. 23 Subgenital plate small, short, extending 

 cauclad as far as median portion of cerci, carinate mesad, with 

 apex broadly U-emarginate, the lateral portions thus formed 

 short, straight, styliform but not articulated. Genicular lobes 

 of caudal femora very weakly bispinose, of other femora bluntly 

 or triangularly rounded. Ventral femoral margins armed with 

 small teeth, those of the cephalic and median femora being minutely 

 microscopic, as follows. Cephalic internal cf 2 to 3, 9 3 to 6, 

 cephalic external 0, median internal 0, median external o 71 and 



9 5, caudal internal c 71 5 to 7, 9 4 to 5, caudal external c 71 7, 



9 10 to 11. 

 Allotype: 9 ; same data as type. [Hebard Collection.] 



Larger and more robust than male, but not showing as great 

 sexual contrast as does phaneropteroides. Coloration similar, the 

 marking of the cephalic tibiae of apparent decided specific diag- 

 nostic value. Ovipositor very short for the genus, curving very 

 gradually upward to the acute apex, dorsal and ventral margins 

 very finely serrulate an equal distance distad, lateral surface without 

 nodes or grooves. Subgenital plate triangular with apex bluntly 

 rounded and ventral surface showing a strong, very slenderly 

 lamellate medio-longitudinal carina, percurrent to near apex. 



General coloration immaculate yellowish oil green, the bodies of 

 the specimens before us being much faded. Tegmina along sutural 

 margin, immediately beyond stridulating area, with veins brown 

 and interspaces toward anal vein blackish, this continued to apex 

 of tegmina along the edge, but the veins become green and the 

 interspaces so small that they are visible only under the lens. 

 Pronotum, abdomen and femora microscopically dotted with 

 hydrangea red. Cephalic tibiae in area of auditory foramen 

 washed with hydrangea red and there, on dorsal surface, suffused 

 with blackish. 



Length of body d 71 (shrivelled) 15, 9 22.3; length of pronotum 

 cf 4.7, 9 4.8; caudal width of pronotum <? 2.7, 9 3; depth of 



23 The general type is as in phaneropteroides, the lamellate distal portion in 

 that species being, however, proportionately smaller, narrower, ovate and in 

 position decidedly beyond the apex of the decidedly less produced anal tergite.
