Type-species: Cicada irrorata Fabricius. 



Length 10.5-13 mm. 



Head with median length equal to or less than interocular width, 

 anterior margin slightly carinate (exception: P. piper ata (Fowler)), 

 ocelli located on or slighdy before a line between anterior angles of 

 eyes, each equidistant between adjacent anterior eye angle and median 

 line or slightly closer to latter, with or without an M -shaped elevation 

 bordering posterior margin, with a median fovea (exception: P. 

 piperata (Fowler)) which is broadened anteriorly, disc usually pubes- 

 cent; antennal ledges with or without a longitudinal sulcus, in lateral 

 aspect carinate or not dorsally; clypeus depressed or convex beneath 

 apex of head; other characters as in Aulacizes. 



Thorax as in Aulacizes. Forewing with a membrane which is variable 

 in extent and occasionally not well delimited, veins elevated and 

 distinct, clavus and corium with texture varying interspecifically 

 from translucent to opaque, clavus varying from very sparsely to 

 densely punctate and occasionally with punctures extending into 

 adjacent brachial cell, base of fourth apical cell usually located more 

 proximally than base of third, other characters as in Aulacizes. Hind- 

 wing at rest extending almost as far posteriorly as apex of forewing; 

 vein Ro-fs complete (exceptions: P. thunbergi (St&l), P. aurantiaca (Sig- 

 noret)). Hindlegs as in Aulacizes. 



Male genitalia: Pygofer not strongly produced, rounded apically 

 with dispersed microsetae, with a pair of processes arising usually 

 near middle of each side of dorsal margin, extending ventrally and 

 inflated, in caudal aspect appearing as thickenings of conjunctiva 

 IX-X (occasionally not in contact with dorsal margin, appearing 

 then as distinct sclerites). Plates as in Aulacizes. Style extending pos- 

 teriorly as far or nearly as far as apex of connective, with distinct 

 preapical lobe, with apical portion foot-shaped, the "toe" directed 

 mesally (exception: P. confusa (Signoret)), with a few serially arranged 

 microsetae beyond apical lobe. Connective elongate, narrowly Y-
