dd. Disc of the pronotum rounded, furnished with a median, sHghtly 

 elevated, longitudinal line. 

 e. Lateral lobes of the pronotum as high as long. Tegmina some- 

 what pellucid, the transverse veins not prominent, rather poorly- 

 expressed. Legs not especially slender. Anterior femora but 

 little longer than the pronotum, the posterior pair not more than 

 four times as long as the pronotum .... Grammadera Brunner. 

 ee. Lateral lobes of the pronotum longer than high. Tegmina grass- 

 green, opaque, the transverse veins elevated, parallel. Legs 

 very slender. Anterior femora one-half longer than the pro- 

 notum, the posterior pair five times as long as the pronotum. 



Abroidiata Brunner. 

 cc. Posterior radial vein emitting several non-forked parallel branches. 

 Lateral lobes of the pronotum angulately inserted. (Fastigium of the 

 vertex more or less laminately compressed. Anterior and middle 

 tibiae sulcate above, totally unarmed.) 

 d. Tegmina narrow, the branches of the posterior radial vein longitudi- 

 nal, terminating in the apex of the elytra. Fastigium of the vertex 

 a trifle longer than, or of equal length with, the first antennal joint. 

 Lateral lobes of the pronotum higher than long, their posterior 

 margin more or less angulately produced. Tegmina wider at 

 base, tapering towards the apex. Ovipositor gently curved. 



Tomeophora Brunner. 



dd. Tegmina strongly dilated, ovate or trapezoidal, the radial branches 



oblique and running out on the posterior margin of the elytra. 



Viadana Walker. 

 bb. All the femora sulcate below. The subgenital plate of male provided with 

 styles. Ovipositor rarely longer than the pronotum, generally, but not 

 always, suddenly curved, roughened, acuminate, or smooth with the apex 

 truncate and crenulate, but obtuse. 

 c. Mesosternal lobes triangular, not produced; the metasternal lobes 

 rounded, except in the genus Diplophyllus, where they are triangular. 

 Ovipositor acuminate. Fastigium of the vertex also acuminate. 

 d. Fastigium of the vertex not touching the fastigium of the front. (In 

 Phyllopiera peruviana they touch.) Internal margins of the an- 

 tennal scrobes when viewed from the front include the fastigium 

 of the front. Front more or less tumescent. (Metasternum 

 roundly lobate.) 

 e. Wings surpassing the tegmina. 



/. Secondary veins of the tegmina irregularly placed. 



g. Lateral lobes of the pronotum often higher than long, the 

 anterior margin sinuate. Anterior and middle tibiae less 

 graceful. These hardly longer than the pronotum. 

 Ovipositor a little shorter than the pronotum, its base 

 and apex equal in width. Cerci of male thorter, curved 



inwards Phyllopiera Serville. 



gg. Lateral lobes of the pronotum as long as high, the anterior
