96 BRITISH CICAD.E. 



Large. General colour of the live insect a fine green, 

 which fades subsequently in cabinets to brownish green. 

 A feeble ridge on the sides of the pronotum, which has 

 marked striffi ranged horizontally with no central ridge. 

 Post-scutellum large. Elytra greenish, with brighter 

 green nervures. Apical border thickened, and the lower 

 claval border also strengthened. Legs bright green. 

 Tarsi ending with rounded pads. The neuration in 

 both elytron and wing is liable to considerable variation 

 in its details. Some specimens thus differ one side 

 from the other. Navicular valve of the female large 

 above the saw-case. Anal opening oval. Under-side 

 greenish brown. 



Common on oaks at Haslemere. July and August. 



Inch. Millimetres. 



Expanse 0-36 9-14 



Length of body 0-17 4-24 



N.B.— The fine hairs on the inner side of the hind 

 tibia) have been by error omitted in my plate. 



Genus XXL— BYTHOSCOPUS, Germ. 



Two radial nervures enclose a rhombic basal cell, 

 from the apex of which another radial nervure springs. 

 This by furcation forms two discoidal, three sub-apical 

 and five apical cells to the elytron. Frons convex. 

 Ocelli below the edge of the vertex on the upper part 

 above the frons. 



The characters of Bijtlwscopns, perhaps, are hardly 

 sufficiently distinct for a generic separation from 

 Macropsis ; but I prefer to follow Fieber and others, 

 to avoid a further confusion in the synonyms.
