ON THE BKITISH SPECIES OP THE G-ENUS CIXIUS. 

 BY JAMES EDWAEDS, F.E.S. 



The following species of this genus are noticed by Mr. Scott in 

 his Eevision of the Cixiidce, in vol. vii of this Magazine, p. 121, 

 et seq. : — 



1. cunicularius, Fab. 



2. nervosus, Linn. The very long recurved teeth of the anal tube in 



the <$ of this common species are very characteristic. 



3. intermedins, Fieb. This is a synonym of the next species, teste 



Fieber, Cicad. d'Eur., pt. ii, p. 179. 



4. br achy cr anus, Fieb. 



5. eontaminatus, Latr., =pilosus, 01. This is, so far as I know, our 



only representative of the group which is characterized by having 

 the marginal nerve granulate between the nerves of the mem- 

 brane. 



6. stigmaticus, Germ. 



7. simplex, H.-Schff. This is not the true species of that name, and 



I, therefore, propose to call it O. Scotti. 



8. similis, Kbm. Scott's species not being the same as Kirschbaum's, 



I propose to call the former C. remotus. I am indebted to the 

 kindness of Mr. C. "W". Dale for the opportunity to make these 

 corrections with regard to this and the preceding species. 



The more salient characters of the two last named species may 

 be briefly stated as follows : — 



Cixius Scotti. 



= simplex, Scott. 

 Head black, with brownish-yellow keels. Pronotuui brownish-yellow, beyond 

 the side keels black. Scutellum black, the middle keel generally brownish-yellow. 

 Elytra lacteo-hyaline, nerves white, stigma black, apical areas frequently with 

 fuscous blotches ; the inner margin generally with two black streaks, one adjoining 

 the apex of the axillary nerve, and the other a little nearer the base ; opposite to 

 the latter streak there is frequently a trace of a fuscous transverse band ; nerve 

 granules oblong, narrowed at each end, costal granules 12 — 14, occupying the whole 

 width of the nerve. Anal tube and styles similar to those of C. remotus, but the 

 aperture of the former is transversely oval. 



This species is probably not uncommon in the South ; I have 

 several examples from Mr. Dale, and Mr. Saunders has taken it at 

 Penzance.
