 posterior ulnar simple. Wings hyaline , costal margin faintly 

 suffused with castaneous , mediastinal vein bifurcate , 7 costals, 

 the last 2 ramose, the first 4 clavate, ulnar vein ramose, triang-

 sub-genital lamina exceeding it, apex slightly produced, excised, 

 a pair of short blunt styles , their apices minutely denticulate 

 dorsally. Cerci long , slender , fuscous beneath. Front femora 

 completely armed on the anterior margin beneath , the distal 

 spines the shorter.

(f. Testaeeous. Frons obscurely marked with castaneous dots 

 and lines. Pronotum transversely elliptical , margins broadly 

 hyaline, disc with symmetrical liturate markings. Tegmina barely 

 exceeding the apex of the abdomen , testaceo-hyaline , the veins 

 rufescent ; about 10 costals , many ramose, radial simple, 5 dis- 

 coidal sectors, posterior ulnar simple, numerous transverse venules

 9 costals, the first 6 strongly clavate, ulnar 4-ramose. Abdomen 

 above blotched with castaneous , the last 3 tergites constricted,

 with a large piceous macula on sternites 1 — 6, sub-genital lamina 

 large, produced, considerably exceeding the supra-anal plate , its 

 apex slightly emarginate, styles slender, situated in deep notches 

 on either side of the apex, some stiff, erect hairs at their points 

 of insertion. Cerci rather short, flattened, outwardly curved. 

 Front femora with a complete row of spines on the anterior
