THE SPECIES OF THE NEW GENUS NEOTETTIX WITH A 

 KEY TO THE GENERA OF NORTH AMERICAN TETTIGI/E. 



By J. L. HANCOCK. 



(See Plate VIII.) 



In the present notes are described several species of Tettigians 

 of a hitherto unrecognized genus from the southern United States. 

 I have, furthermore, outlined a table of the genera of Tettigiae, 

 including therein the new genus Neotettix, together with the 

 three already known to occur within our borders. These are 

 namely: Nomotettix Morse, Neotettix gen nov. , Paratettix Boli- 

 var, and Tettix Charpentier. The species of Neotettix are small 

 in stature, in which particular they resemble Nomotettix. The 

 wings are frequently abbreviated, and macropterous as well as 

 brachypterous forms are represented among them without the 

 apical process of the pronotum being much of it at all extended 

 further backwards than the knee of the hind femora. These 

 dimorphic phases of structure are not considered separately. It 

 will be observed that Bolivar, in 1887, described a species in his 

 Essai sur les Acridiens de la tribu des Tettigidae p. 246, as Teltix 

 femoratus Scudder. That there is a discrepancy regarding the 

 identity of the species seems fairly certain. A specimen which 

 was identified by Prof. Bolivar as strictly this species was pre- 

 viously kindly examined by Mr. Scudder, the author of the spe- 

 cies, who informed me of a difference existing in the width of 

 the vertex between the eyes as compared to the original/*? moratus. 

 Partly on the strength of Mr. Scudder's assertion : " It is quite 

 certain that the specimen you send cannot be that species from 

 the width of the vertex between the eyes" and the knowledge 

 gleaned from an examination of a considerable series, I have 

 proposed the appellation Neotettix bolivari in deference to my 

 distinguished colleague. The generosity of Mr. A. Bolter, of 

 Chicago, who placed his collection of this group freely at my 

 disposal made it possible to include two of the three species here 

 described. One of these I take pleasure in naming in his honor. 

 It is quite probable that the species described by Scudder as 

 Tettix femoratns in "Transactions American Entomological So- 

 ciety" ii, p. 305, will, in the course of time, be restored, or as 

 soon as sufficient material from Maryland, where the type came 

 from, has been carefully studied. This species, of which the
