Genus Osmilta Stal. 

 Osmilia Stal, Recens. Orthopt., I, p. 68 (1873). 



The genus Osmilia is made up of a number of closely related tropical 

 American species, which are quite difficult to separate, especially in 

 the case of the forms described by the earlier authors. At least four 

 of the nine species listed by Kirby in his Catalogue of Orthoptera 

 belong to Brazil.
