The Tettigoniellinse are readily recognized by the position of the 

 ocelli which are placed on the disk of the vertex : the face is large, 

 prominent, strongly convex ; cheeks long and narrow ; antenor 

 edge of the head obtuse or rounded. 



The question of the name of this subfamily, based on the 

 alteration of the name Tettujonia to TettijonieUa, is discussed on 

 pp. 201-2. 



Melichar includes in this subfamily the genera Penthimia and 

 Neodartus, which I follow Van Duzee in locating in the Gyponinge.* 

 In the Neotropical species ascribed to Tettigonia (TettigonieUa) 

 it is evident from the figures published that many distinct genera 

 have still to be described, and a monograph might well be devoted 

 to the beautiful insects from all parts of the world that are already 

 known as belonging to the Tettigoniellinae. 



>Sijno2:)sis of Genera. 



A. Wings a little broader than tegniiua, their 

 apices rounded. 



a. Face neither centrally carinate nor fo- 



veate. 



a. Lateral margins of vertex in a line with 



inner margins of eyes. 



a^. Vertex not foveate Tettigoniella, p. 201, 



6\ Vertex broadly foveate Bhandara, p. 221. 



b. Lateral margins of vertex in a line 



with outer margins of eyes Kolla, p. 223. 



b. Face centrally carinate. 



a. Anterior margin of pronotum not pro- 

 duced between eyes. 

 «'. Vertex centrally carinate but not 

 sulcate. 

 a'-. Vertex crossed by a more or less 

 straight ridge from near one 

 ocellus to the other Euacanthus, p. 227. 



* Melichar also iucludes bis genus Pythamus, which I suspect also belongs 

 to the Gyponinse.
