armed above but armed beneath, as are also the middle ones, 

 with several pairs of medium fixed spines ; hind tibiae armed 

 on both margins above and below, with an apical spine above 

 next the apical calcar on the inner side only; fore and middle 

 femora armed beneath on the cephalic margin only with 

 short stout spines, two on the anterior and three on the mid- 

 dle ones; hind femora strongly swollen in the basal half, 

 armed beneath on both margins with short stout spines, three 

 or four on the inner and four or five on the outer ; genicu- 

 lations of all the femora acutely angulate, those on the inner 

 side of the middle ones and on both sides of the hind ones 

 being spinose. Tegmina but little longer than the pronotum 

 and about half as broad as long, apically broadly rounded, 

 especially in the male ; stridulating vein of the left tym- 

 panum of the male very thick but not angularly projecting 

 beyond the anal margin. Plate I, figure 10, shows the shape 

 of the tegmina of the male ; wings abortive, forming mere

 apical chitinized point, of 9 simple, round and tapering to 

 a point, the whole about four times as long as basal width 

 and gently curved inward ; ovipositor somewhat longer than 

 the pronotum and shaped as in Plate II, figure 13. 



General color green, in cabinet specimens yellowish green ;

 foramina of the anterior tibiae, the apex of the mandibles, 

 and the lateral carinae of the pronotum, especially the ends, 

 black ; the eyes are blackish and the anal margin of the elytra 

 and the tympanum of the $ are marked with blackish ; none 

 of the above-mentioned black markings are conspicuous, 

 those of the pronotum and the tegmina of the male being the
