564 MONOGRAPH OF THE AUSTRALIAN CICADIDjE, 



large, little exposed. The tegmina each have one basal area, from 

 which pass out one or two ulnar veins, and one radial vein, the 

 branches forming the various areas, there normally being three 

 discoidal, two ulnar, one radial (or costal), and eight apical areas, 

 and the clavus, which is very narrow. The front coxa? are oblong, 

 prismatic, inserted in the front angles of the prosternum; the 

 middle and posterior are longer, subconical, subcontiguous, remote 

 from the sides of the body. The front femora are thickened, 

 frequently spined below. The tibiae are smooth. The tarsi are 

 composed of two or three articles, with no arolium. The base of 

 the abdomen in the male is furnished with two sound organs, 

 which are attached to the tympanum.
