Hippacris nov. gen. (i'-ros, axp)s.) 



Head full, rounded, but the front appressed ; tubercle of vertex 

 nearly in same plane with vertex, a little inclined, broad, narrowing 

 beyond the eyes, but squarely docked, flat; the middle of the inner 

 edge of the eyes midway between its tip and the base of the head. 

 Front on a side view vertical, but inclined where it projects forward 

 to reach the tip of the tubercle of the vertex, and here only provided 

 with a frontal costa, which narrows a little below and is shallowly 

 sulcate ; space between eyes equal to width of eyes themselves ; 

 these are rather small, rather prominent, round, separated by a little 

 more than their own width from the anterior base of the mandibles; 

 the latter exceedingly stout ; antennae more than twice as long as the 

 pronotum, the joints beyond the second depressed and gradually 

 tapering so as to give them somewhat the appearance of a Truxalis. 

 Prosternum unarmed; pronotum very large, broadening posteriorly 

 so as to be fully doubly as wide behind as in front; the disc ex- 

 panded so that the lateral carinas become very prominent, increas- 

 ingly so posteriorly, directed outward rather more than upward, and 

 serrulate; it is destitute of a median carina, and is traversed trans- 

 versely by three slenderly impressed, equidistant, parallel, curved 

 lines, the convexity backward, the hinder in advance of the middle 

 of the disc; front border straight, a little excised in the middle, 

 hind border obtusely and roundly angulated. Tegmina slender, 

 nearly equal, the tip rounded, fully as long as the abdomen. Wings 

 rather narrow. Legs not very stout, the hind femora flattened 

 above with a sharp superior carina and a similar lateral one. Valves 

 of the ovipositor very stout, their tips strongly curved and pointed. 



I do not know of any genus to which this is closely allied. By 

 Stal's tables (Recensio Orth., i) it should belong to the Truxalidae, 

 which the shape of the antennae favors ; but the small size of the 

 eyes coupled with the almost or quite vertical front, and the posterior 

 lobe of the pronotum longer than the anterior, is at variance with his 

 statement. In some respects it resembles Rhomalea, in others Tro- 

 pinotus, but the prosternum is wholly devoid of armature.
