XI. BYTHOSCOPIDES. 



Ocelli on the frons. Hind tibiae spurred on the edges. 

 Vertex wide and short. Front tibiae without spines. 

 Cubital vein of the elytra forked. Sub-cubital vein 

 joined by a transverse nervure to the brachial vein. 



XII. TETTIGONIDES. 



Frons gibbous. Clypeus very convex ; portion be- 

 tween the clypeus and the crown rounded. Femora 

 with two spines at the apex and on the upper side. 

 Tibi^ multi-spinose. Ocelli a little in advance of the 

 middle of the vertex. Elytra parchment-like and 

 much longer than the body. Antennae springing from 

 sutures between the eyes. 



XIII. ACOCEPHALIDES. 



Vertex generally separated from the frons by a ridge. 

 Ocelli placed near this ridge, if it be present ; but if 

 absent, on the forehead. Elytra with strongly raised

 marginate. Hind tibiae four-sided, each edge furnished 

 with a row of spines.

Insects small and linear. Ocelli absent or difficult 

 to see. Face longo-triangular. Elytra overlapping at
