Vertex strong, the anterior margin sharp; length not quite equal to 

 the width between the eyes; ocelli colorless, closer to one another than 

 to the eyes. Eyes oval, elongate, brown, prominent; anterior of head 

 rounded. Face strong, black, interspersed with yellowish spots on the 

 margin, slightly convex, flat on middle, with numerous transverse fur- 

 rows; frons with some yellow irregular spots; clypeus yellowish, long, 

 produced, heart-shaped, about two-thirds of the length of the frons; 

 rostrum long, black at the tip; loras long, very narrow; cheeks narrow 

 next the lorae wider beneath the eyes. Pronotum dull brown, the 

 anterior margin broadly rounded, side margins very acute, posterior 

 somewhat concave; flat on top, with two small depressions alongside 

 the median line; length of pronotum greater than the vertex, the breadth 

 about twice the length. Scutellum much longer than broad, the apex 

 sharp; venter of thorax black, the pro-, meso-, and metapleura with 

 yellow borders. Elytra dull brown, with many irregular black mark- 

 ings, the margins lighter; venation distinct, apex of elytra sharply 

 rounded. Abdomen yellow beneath, with black for the base. Legs 

 yellowish with brown spots. Genitalia — female; last ventral segment 

 not quite as long as the penultimate; pygofers yellow, broad, flattened, 

 twice as long as their width at base; ovipositor brown, sharp, a little 

 longer than the pygofers.

SUPERFAMILY JaSSOIDEA. 



The members of the Superfamily Jassoidea may be recog- 

 nized by the character of the tibiae, which are prismatic in shape, 

 and armed with a row of spines on their posterior margins. 



Synopsis of Families. 

 The following key, taken from Osborn's work on the 

 Jassoidea of Maine, will illustrate the main characters of the 

 subfamilies. 



A. Elytral nervures forking on the disk. 



b. Ocelli located on the disc of the vertex Tettigoniellidae 



bb. Ocelli located on border of vertex between vertex and front.. Jassidae 

 bbb. Ocelli located on front distinctly below border of vertex. . . . 



Bythoscopidas 



AA. Elytral nervures forking at base and running to apex of elytra, ocelli usually 



wanting Typhlocybidae 



Besides the works of Walker and Distant, the more 

 important publications on the South African forms are those 

 of Melichar, Signoret, Distant and Burmeister.
