This genus is distinguished from Acrida^ not only by its an- 

 tennae, filiform at the base, and capillary at the apex, and by its 

 rough cymbiform ovipositor, but in the number of teeth that arm 

 its mandibles, in wanting the remarkable elevation between the 

 antennae, in having eyes less prominent and of a diflerent shape,
