THE NORTH AMERICAN SPECIES OF NEMOBIUS. 



By Samuel H. Scudder. 



The North American species of the Orthopteran genus Netnobius 

 Serville are more numerous than has been supposed, notwithstanding 

 that several species have been more than once described as distinct. 

 Prof. L. Bruner, of Lincoln, Neb., has kindly sent me a considerable 

 series from his collection; Mr. A. P. Morse, of Wellesley, Mass., has 

 placed ^his collection, mainly from New England, in my hands ; the 

 collections of the Museum of Comparative Zoology and of Mr. S. Hen- 

 shaw have been at hand ; and these, with a {^w specimens from the Na- 

 tional Museum, added to my own, form the basis of the following ta- 

 ble and descriptions. Although Trinidad belongs zoologically to South 

 America, I have added one species found there. The number of 

 known species is hereby doubled, and doubtless more await discovery. 



I should add that '^ Nemobiits circufncinctus " Scudd. (Proc. Bost. 

 Soc. Nat. Hist., XII, 143) from Mexico is a Prothacustes and iden- 

 tical with the later described P. mexicatia Sauss.; the species given by 

 Provancher (Faune Ent. Can., II, 24) as ^' Nemobius {Anaxipha) 

 septefitrionalis Scudd." was named for him by me as Anaxipha septen- 

 trionalis, but it is identical with Anaxipha exigim (Say); it was for- 

 merly (Nat. Canad., VIII, 61) called by him Nemobius exiguus, as 

 Say's species; an insect referred to as '■^ Nemobms marginata'" by 

 Miss Murtfeldt (Ins. Life, V, 155) is probably an accidental error, as 

 no such name has been given ; " JVemobius ? pulicarius^^ Walk. (Cat. 

 Derm. Salt. Brit. Mus., I, in), is an Anaxipha. This covers all the 

 North American species referred to Nemobius, except those given be- 

 low in the synonymy. 



I have followed Saussure in employing the female alone (or almost 

 alone) in constructing the following table, since the males of several of
