Characters. — Head about as long as pronotum, including eyes about as wide as base of meso 

 notu-m. vertex longer than front, its lateral margins discontinuous, that of vertex not in line with that of 

 front; pronotum a little shorter than mesonotum, its lateral margins straight, not ampliate, its posterior 

 ang'es moderately ampliated; mesonotum with the disk convex; abdomen short, about as long as space 

 between apex of head and base of cruciform elevation; tympanal coverings incomplete, narrower but 

 scarcely shorter than the tympanal cavities, which are thus inwardly exposed; rostrum almost reaching 

 the posterior coxas ; opercula in male small, narrow, not extending beyond basal abdominal segment; 

 anterior femora strongly spined beneath ; tegmina and wings hyaline, the first with eight apical areas 

 and the basal cell not twice as long as broad.

 tympanal cavities; opercula in male very small, not covering the cavities; rostrum reaching the poste- 

 rior coxae; anterior femora spined beneath; tegmina and wings hyaline; tegmina with the b^sal cell 

 much longer than broad, apical areas eight, wings with five apical areas.
