47. Genus ONCOMETOPIA Stal, sensu lato 

 FiGXHiES 207-219 

 Oncometopia StS.1, 1869a:62. Type-species: Cicada undata Fabricius, pre- 

 occupied, — Cicada orbona Fabricius, by subsequent designation of 

 Distant, 1908b:62. 

 Parametopia Melichar, 1925a:387, preoccupied. Type-species: Cicada orbona 



Fabricius, by subsequent designation of Schmidt, I928c:71. 

 Lebora China, 1927d:283, as new name for Parametopia Melichar. 



Length 9.4-15.0 mm. 



Head moderately produced, its median length almost always less than 

 interocular width, anterior margin rounded in dorsal aspect, crown 

 rounded to face without a carina between the two, ocelli each about 

 equidistant from median line of crown and adjacent anterior eye angle 

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

 posterior margin, disc without a median fovea, usually with short 

 sparse pubescence; antennal ledges each with longitudinal fovea, each 

 carinate dorsally, with anterior margins oblique; clypeus strongly 

 convex, not flattened nor concave medially (exception: female of 

 0. fuscipennis Fowler), with dorsomedial surface texture coarsely gran- 

 ular; other head characters as in Phera. 



Thorax with pronotal disc punctate and usually rugose, with or 

 without pubescence; proepimeron with lower marginal area not de- 

 pressed and with width of proepimeron greater than length; posterior 

 portion of scutellum almost always without transverse striae; other 

 thoracic characters as in Phera. Forewing coriaceous, with an apical 

 membrane (sometimes very narrow), veins distinct, surface often 

 punctate, claval veins parallel, approximate, contiguous, or fused near 

 their midlength, otherwise as in Phera. Hindwing as in Phera (exception : 

 0. {Similitopia) alpha, see p. 230). Anterior tibiae not or only slightly 

 dilated apically. Hindlegs with first tarsomere variable in length, 

 shorter than, equal to, or longer than combined length of second and 

 third posterior tarsomeres, otherwise as in Phera. 



Male genitalia: Pygofer in lateral aspect usually short and broad, 

 with numerous dispersed microsetae and occasionally with interspersed 

 macrosetae, almost always with at least vestigial processes arising on 

 ventral margin, and occasionally with additional process-like (but 

 usually not differentially sclerotized) extensions which are dorsoapical 

 or apical in origin. Plates as in Phera. Style extending as far as or farther 

 posteriorly than connective or not, with or without a distinct preapical 

 lobe, from rounded to angulate or truncate at apex. Connective broad, 

 widely separating styles, Y-, T-, or U-shaped, keeled medially. Aedeagus 

 quite variable interspecifically and in some species intraspecifically, 

 always rather large, frequently with processes which may or may not 

 be symmetrically arranged. Paraphyses absent.
