TBYXALIDJE. 



Genus AcRiDA. 



Gryllus (Acricla), Linnaeus, Syst. Nat. (ed. x), p. 427 



(1758). 

 Acrida, Stal, Rec. Orth., i, pp. 88, 95 (1877). 

 Truxalis, pt. Fabricius, Syst. Ent., p. 279 (1775). 

 Tryxalis, Bolivar, Feuille Nat., xxiii, p. 41 (1893). 



The type of Truxalis has been fixed as an American 

 species; the types of Tryxalis, Blanchard, belong to the 

 next genus, and therefore Acrida, Linnaeus, must be 

 retained, with A. turrita, Linnaeus, as the type. 



A. turrita, Linnaeus, and A. gigantca, Fuessly, are 

 usually united under the name of A. nasuta, Linnaeus ; 

 but they appear to be distinct, and the true A. nasuta 

 belongs to the following genus. 



10. Acrida turrita. 



Grylhis {Acrida) tunntus, Linnaeus, Syst. Nat. (ed. x), i, 



p. 427, n. 12 (1758). 

 Acrida turrita, Stal, Rec. Orth., i, p. 96, n. 3 (1873).
