A. — Ocelli 3. Pedes postici haud saltatorii. (Stridulantia.) 

 Genus i. — cicada, Lin. 



Cicada Anglica, Leacli. 



For a description of this insect see Curtis, B.E., pi. 392. It is 

 closely allied to G. h(smatodes, Liu., but the neuration of the wings is 

 slightly different, and such a discrepancy must be constant and specific. 

 C. hcematodes has seldom been found so far north as Paris. I have 

 taken it in the south of Prance and in Corsica, but did not hear its 

 voice. Our own species is said to be mute, but the truth probably is 

 that it stridulates feebly (like li<smatodes) ,?indi that no one has happened 

 to hear it. On this subject see Douglas in Trans. Ent. Soc, 1858, vol. 4. 

 Proc. p. 65. It has occurred only in the New Porest.* 



B. — Ocelli 2. Pedes postici saltatorii. (Muta.) 



I. Pulgorina. 



Greuus ii. — cixms, Latr. 



t Antennae medio inter oculos et clypeum insertse. 



1. — Ciccius nervosus, Lin. 



Eostrum ad coxarum posticarum apicem usque productum. [See Plor. 



Eh. L. 2, p. 21.] 



Corp. long. 2-2^ lin. ; alar. exp. 5^-8 lin. 



Head and pronotum testaceous, the former with two black spots in 

 the fovefe of the vertex. Spaces between the the frontal carinre black. 

 Scutellum black. Hemelytra hyaline, usually with one or two faint 

 brown transverse bands before the middle ; a distinct brown stigmatical 

 spot on the costa near the apex, sometimes with a much fainter spot 

 beyond it. Costa with about 20 black dots, larger than those which 

 beset all the pale nervures of the hemelytra. 



The largest and commonest British species. It varies occasionally, 

 as foUows : — 

 Var. a. — Hemelytra fascia latiori ante apicem, et maculis quibusdam 



disci irregularibus brunneis. (O. e unicularius, Lin. ; Dionysii, 



Panz.) 

 Var. h. — Similis, sed alarum apex litura magna brunnea. 

 Var. c. — Hemelytra fere tota brunnea, apice hyaline. (C. Dionysii, 



Curt. B.E.) 

 Var. d. — Minor ; scutellum obscure ferrugineum, s. nigro-plceum ; he- 



melytrorum maculae parvse, inconspicuae ; maculae costales 



nigerrimae, valde distinctae. (C. stigmaticus, Latr.) 



* Mr. C. G. Barrett, of Hasleraere, has lately taken this species in Surrey. Vide p. 171.
