 Kahavalu, gen. nov. 



This seems somewhat near Ulopa Fall (a Membracid) on the 

 one hand and Megophthalinits Curtis, on the other. It is distin- 

 guished by the ocelli being each in a groove on the rounded an- 

 terior margin of the vertex ; the pronotum very slightly sinuate 

 posteriorly, not carinate and no process ; scutellum free. Head 

 pronotum, scutellum, clavus etc., deeply and closely punctured, 

 making them rugose, a shining point at the bottom of each punc- 

 ture. Vertex short, transverse, flattened, except at the lateral 

 angles. Eyes large, not forming part of the curve of the head. 

 At the anterior margin of vertex there are two elongate grooves, 

 reaching almost to the eye laterally, but not touching medianly. 

 At the extreme interior part of each of these is an ocellus. Frons 

 rather narrow, elongate, slightly convex, lateral margins gently 

 rounded ; antennae in a deep groove near the base. Clypeus not 

 carinate.
