44 STUDIES IX AMERICAN TETTIGONIID AE (oRTHOPTERA) 



describing A. gihhosus from the southern states. In the same 

 paper Scudcler phiced the genus Engoniaspis in his key to the 

 genera of the North American Decticinae ^^ on the basis of an 

 unnamed species, which he presumed was from Missouri, In 

 1900, the same author " described this previously unnamed 

 specimen as Engoniaspis testaceus. Rehn, in 1900, finding the 

 name Orchesticus Saussure, which had been used in connection 

 with a quite different genus, preoccupied by Orchesticus Cabanis 

 in birds, replaced it by a new name Stipator,^- this being due to 

 his use of the older name in the erroneous sense of all authors 

 subsequent to Saussure. Caudell, in 1907, published a revision 

 of the North American species of this subfamily and showed that 

 the genus Engoniaspis is a synonym of the present genus, ^^ 

 the supposed differential characters given by Scudder not being 

 of generic rank. In 1912, Rehn and Hebard ^^ described Atla7i- 

 ticus glaher from southern Florida. 



Nomenclature. — The identity of Burmeister's two species 

 has been universally allowed to rest on the basis of Scudder's 

 1862 placing. However, he had no material from their original 

 locality for study, and the species he examined are different 

 from those found in the region from which Burmeister's material 

 probably came. For discussion of this, see under A. pachymerus. 

 We have before us two species from that region which answer 

 the descriptions of Burmeister. Saussure's Orchesticus and 0. 

 americanus have been erroneously used by all authors for the 

 genus and one of the species of a western genus allied to Atlan- 

 iicus, to which, however, as we have shown beyond, the name 

 has no application. On account of the preoccupation of Orches- 

 ticus by Orchesticus Cabanis in birds, Rehn, in 1900, unfortunately 

 in ignorance of the real application of the name, and following 

 previous authors in its usage, renamed the genus Stipator. This 

 peculiar situation, when corrected by making Stipator a pure 

 synonym of Atlanticus, makes necessary a new name for the 

 Orchesticus of Scudder, not of Saussure, for which we here
