Diagnosis
This seems somewhat near Ulopa Fall. (a Membracid) on the one hand and Megophthalmus Curtis, on the other. It is distinguished by the ocelli being each in a groove on the rounded anterior 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 puncture. 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 (Kirkaldy 1906).
