Salient features of adults. Terrestrial.

Phytophagous. Large; about 20 mm long; the males very noisy, emitting loud, continuous sounds (in numerous species of warm climates, via paired tymbals at the base of the abdomen, the extra-ordinary level of sound production in this family being associated with complex auditory organs that are lacking in other Homoptera possessing comparable tymbals), or not extremely noisy (in that those of the only British representative produce sound of such a high frequency as to be inaudible to many people); fliers; relatively stout bodied. Rostrum not separated from the prosternum by a gula. Antennae longer than the head, readily visible from above; consisting of short segments with a terminal, unsegmented arista that is much longer than the segments. Ocelli present; 3; between the eyes. Tegulae absent. Fore-wings well developed; in the resting insect sloping roof-like over the abdomen; more or less uniform in texture; with transparent cells (glassy between the veins); without costal fracture and cuneus; with a clavus; with conspicuously raised, reticulate venation. Clavus without convergence of veins to form a Y. Hind coxae mobile. The posterior tibiae cylindrical. Tarsi 3 segmented.

Taxonomy. Suborder Homoptera. Auchenorrhyncha. Cicadoidea.
