110 BRTTISn CICADiE. 



wing united before passing to the marginal nervure, 

 whicli last is complete to the anal nervure. The third 

 radial is unforked, but joined to the second by a short 

 transverse nervure. The first radial, for about half 

 its length, is confluent with the upper periphery of the 

 wing ; thus it forms only one apical cell. Genital 

 plate of the male well developed.

Colour somewhat variable. Vertex, pronotum and 

 scutellum dull brick-red. Eyes black. Pronotum wdth 

 pale blackish angular markings. Scutellum with one 

 or more redder streaks. Abdomen reddish, variegated 

 with more or less disjointed black bands, which are 

 broadest towards the apex. Elytra green or greenish- 

 yellow, sometimes with a fuscous stripe and darker 

 claval suture. Legs green or pale olive. Claws or 

 pulvelli (?) black. Wings hyaline, with the first and third 

 radials, and the anal nervure, strongly pronounced. 



The third radial, and its transverse nervure, is 

 sometimes obsolete, or nearly so, in old cabinet speci- 

 mens, due to the failure of pigment. My figure is 

 from a rather faded example in Mr. Douglas's cabinet, 

 and I regret that the omission, from the above cause, 

 of the small transverse vein did not at the time of 

 drawing occur to me. 



Fieber's figure of the wing is in accordance with my 

 description of the generic characters. The wing- 

 neuration in Chlorita, the next genus, is almost identi- 

 cally the same as in lighos ; and the details of my 

 figure 1 d, Plate LXV., will suit both genera.
