lobes nearly or quite twice as long as broad in both sexes. Tegmina 

 uniform light yellowish testaceous, with no sign of maculatiou, although 

 rarely a little beclouded, reaching somewhat, generally far, beyond the 

 hind femora, rather slender, feebly tapering, well rounded at tip ; wings 

 pellucid, the veins and cross-veins sometimes wholly green, sometimes 

 partly fuscous. Hind femora testaceous, generally feebly ini'useated in 

 the incisures of the outer face above, the inner half of the upper face 

 often bimaculate with fuscous, the under surface with a tendency to 

 become roseate, the genicular arc black; hind tibiae very pale dingy 

 green, growing lutescent apically, the spines black with pallid base, 

 ten to twelve, usually eleven, in number in the outer series. Extremity 

 of male abdomen clavate, a little upturned, the supraaual plate subclyp- 

 eate, with sinuate sides and rectangulate apex, with a short, shallow, 

 median sulcus and feebly elevated sides, the whole surface nearly 

 plane; furcula consisting of a pair of moderately broad, flattened, 

 tapering, acuminate fingers, parallel or slightly divergent, reaching 

 about to the middle of the supraanal plate; cerci slender, subequal but 

 basally tapering, feebly incurved laminae, about five times as long as 

 broad, feebly arcuate and apically well rounded, with a slight, inferior, 

 indirected flange to the lower margin apically, the whole much shorter 

 than the supraanal plate; infracercal plates as in the last species; sub- 

 genital plate about as broad as long, the lateral margin arcuate, being 

 produced both basally and apically, but especially the latter, the apical 

 margin rounded subquadrate, very feebly or not at all einarginate, 

 though thickened on either side of the middle.
