This genus includes numerous species, which are spread over all parts of the world. 

 Its members present two somewhat different types, which can be distinguished as 

 follows : — 



1. Superior inner spur of the hind tibia? shorter than the intermediate spur, and the 

 apical valvse of the ovipositor regularly lanceolate, as in Gryllus. 



2. Superior inner spur of the hind tibia? equal to or somewhat longer than the 

 intermediate spur. The apical valvae of the ovipositor shorter, limited at the base 

 by a notch, principally the superior one, and terminating in a long spine; the 

 superior valva longer than the inferior one, the two valvse more or less separated from 

 each other by a notch, their interior borders being sinuated. The species of type 1 

 are more depressed in form, and have the hind tibiae longer. The species of type 2 

 are more cylindric in form ; the females are more or less apterous, and the hind 

 tibiae are generally shorter in proportion. Type 2 somewhat approaches the group 

 Brachytrypites, while type 1 is nearly allied to Gryllus.
