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 

 Us mandibles, in wanting the remarkable elevation between the 

 antennaj, in having eyes less prominent and of a different shape,

nil By a loricate thigh is meant one in which there is an appearance of 

 scales, as in certain kinds of armour. I call those spines that are fixed, and 

 those that are moveable, spurs.
