Representatives of this genus occur both in the Neotropical and Ethio- 

 pian regions. Two forms are known from South America. They are 

 separated thus: 

 A. Tegmina minute, almost hidden beneath the pronotum, the median carina of 

 the latter sinuate; anterior femora subfusiform, the middle one compressed 



and with their carinas undulately lobate fossulafus Bolivar. 



A A. Tegmina small but conspicuous, the median carina of the latter bisinuate; 

 anterior femora compressed, their carinse undulato-lobate . . .lobulatus Stal, 



Prototettix fossulatus Bolivar.
