rangular, with the sides and hind angles perfectly straight. 

 Wings hyaline Flatacanthoides Kirby. 



32. (2[>) Lateral keels of the pronotum deeply cut by the trans- 



verse sulci and, therefore, sinuate. Hind angle of the 

 pronotum attenuate, sharp, with the sides emarginate. 

 Prosternal tubercle with the apex obtusely rounded. 



Martinezius, gen. nov. 



33. (22) Male cerci oblique, recurved, but not hook-shaped. 



34. (35) Smooth. Median keel of pronotum linear, in profile 



straight, scarcely cut by the transverse sulci. Lateral 

 keels linear, practically straight, not sinuate. Supra-anal 

 plate of the male without chitinous tubercles or with but 

 a pair of scarcely distinct submedian tubercles. Pro- 

 sternal tubercle obtusely conical. Callipfanmlus, gen. nov. 



35. (34) Strongly rugulose and tuberculate (reminding some 



members of Oedipodini). Median keel of pronotum raised, 

 in profile crested, deeply dissected by the transverse 

 sulci. Lateral keels strongly sinuate, or interrupted. 



36. (37) Prosternal tubercle conical. Lateral keels of pronotum 



deeply cut by the transverse sulci and sinuate, but com- 

 plete. Supra-anal plate of the male with a pair of sub- 

 median carinulae, instead of tubercles. 



Brachyphymiis, gen. nov. 



37. (36) Prosternal tubercle quadrate, truncate at the apex. Lateral 



keels of pronotum in the shape of a row of interrupted 

 carinulae and tubercles. Supra-anal plate of the male 

 with two submedian tubercles. . . . Euryphymus Stal. 



38. (21) Elytra lateral; their pre-radial field strongly dilated and 



emarginate behind. Wings not developed. Male cerci 

 foliaceous. Prosternal tubercle with the apex pointed, 

 attenuate Acrophymns, gen. nov. 



39. (20) Male cerci oblique, about twice as long as broad, elongato- 



triangular, hollowed out from the inner side, with the 

 lower margin bearing several teeth. Supra-anal plate of 

 the male rounded with a pair of fairly large tubercles at 

 the outer basal angles and a row of four tubercles about 

 the middle. Prosternal tubercle truncate. 



Aneuryphymus, gen. nov. 



40. (19) Median keel of the pronotum very feeble; lateral keels 



obliterate. Head and pronotum strongly rugose. Wings 

 coloured Plegmapterus M. Fern. 



41. (18) Pronotum constricted before the middle and strongly 



compressed laterally; median keel very high, tectiform, 

 bidentate in prozona, convex in metazona. Lateral keels
