posterior radial vein stoiit ; ulnar vein branching at about the 

 middle ; legs stout and lobately armed ; anterior tibiae wholly 

 unarmed, the foramina conchate, little expanded and not ex- 

 tending above the dorsal surface of the tibiae ; middle 

 and hind tibiae unarmed beneath, above furnished 

 with a few apically rounded flattened projections on 

 each margin, the posterior ones with a broad one near 

 the base, no apical spines but with a single pair of ventral cal- 

 cars, short and stout ; the middle tibiae are very much broad- 

 ened in the basal two-thirds ; anterior and intermediate femora 

 compressed, about four times as long as broad, unarmed above, 

 beneath armed on the cephalic margin with four very broad, 

 flat, triangular teeth and on the opposite margin with one or 

 two small tubercles ; posterior femora not strongly swollen 

 basally, unarmed above, beneath on the cephalic margin with 

 three large flat triangular spines in the distal half and with five 

 or six small ones on the proximal half, the opposite carinse 

 with five or six very small sharp spines in the apical two- 

 thirds, the basal ones very short, mere tubercles in fact ; all 

 geniculations unarmed. Abdomen flattened, the 2, 3 and 7 

 segments dorsally somewhat lammellately compressed and 

 slightly prolonged posteriorly ; supraanal plate slightly broader 

 than long, dorsally roundly convex and apically broadly 

 rounded ; subgenital plate a little broader than long, posteriorly 

 narrowed and apically with a broad mesial notch ; cerci simple, 

 no more than twice as long as broad, suddenly constricted 

 mesially to less than half the basal width ; ovipositor one and 

 one-half times as long as the pronotum, curved strongly up- 

 ward in the basal third and apically gently enlarged, the upper 

 margin bluntly serrate in a little more than the apical half, the 

 serration of the apical fourth or fifth larger and forming a 

 double row ; the lower margin is tuberculously serrate in the 

 apical half, the teeth larger apically and covering also the lateral 

 surfaces of the lower valves.
