Belyta and Cinetus are so much connected, and the females 

 are so similar, that until we have the sexes of the different 

 species it will be difficult to determine whether the genera 

 ought to be separated or united. Jurine distinguishes Ci- 

 netus by the triangular costal cell, and the antennae of the 

 males are 14-jointed, those of the females 15-jointed. Since 

 the plate was engraved I have availed myself of Mr. Haliday's 

 papers, and I have scarcely any doubt that the fig. 1 a, belongs 

 to Jurine's genus Belyta; I have therefore not incorporated 

 the characters of this sex in the generic description, but I 

 strongly suspect some of the females have antennae very similar 

 to the figure above alluded to. 



The following species have been already detected in Britain, 

 although only one has ever been recorded, except in the Guide, 

 and there is no figure of the genus, I believe, in any work, 

 British or foreign. 



1. C. Rubecula Hal.— Curt. Guide, Gen. 573. 1. 



2. C. bicornis Ste. 



SW C. arraatus Hal. Male !-§- line long; black, shining and slightly pilose, 

 tip of the 1st and base of the 2nd joint of antennae castaneous, 

 angles of postscutelluni very acuminate. Wings fuscous, nervures 

 piceous. Legs ferruginous, base of coxee, middle of thighs and of 

 4 anterior tibiae and tarsi at the apex piceous. 



3. C. gracilis Curt. If- line long : similar to No. 2 '' but more slender ; 



the 3rd joint of antennae is strongly sinuated, the base of abdomen 

 castaneous, the legs are entirely ochreous and the open stigma is 

 elongated. June, Bexley, Kent. 



4. C. gracilipes Curt. 2\ lines long : black shining ; peduncle slender, as 



long as the abdomen : wings slightly yellow, nervures ochreous, 

 antennge and legs ferruginous ochre, the former fuscous at the 

 apex, posterior thighs castaneous. 



5. C. fuliginosus Curt. \\ line long : similar to No. 4; the abdomen much 



narrower, and oval. Wings dusky, nervures piceous. 



6. C. Cantianus Curt. 1 line long : black, shining : wings transparent, 



the open stigma elongated : legs ferruginous brown, antennae cas- 

 taneous at the base, submoniliform in the female. 



7. C. Vigil Hal. 



8. C. maurus Hal. 



9. C. Numida Hal. 



10, C. nigripennis Hal. April, Holy wood. 



12. C. ruficornis Curt. Female 1§^ line long: robust, black and shining, 



angles of postscutellum produced ; peduncle short and thick : 

 wings yellow, the open stigma elongated, nervures piceous : an- 

 tennae and legs rufous ochre, the former moniliform. 



13. C. maculatus Hal. 



14. C. dorsiger Hal. — Brit. Ent.pl. 380. The male figured was taken on 



an oak by A. H. Haliday, Esq. in the county of Galway, Ireland. 



17. C. Cursor Curt. Female. Similar to No. 12. in size and colour, but 



having very short and imperfect wings ; the base and tip of the 

 abdomen are ferruginous. 



18. C, MirmJUo Hal. 



19. C. dryinoides Hal. 



20. C. astutus Hal. 



No. 11. (bicolor Jur.) of the Guide, and probably 14, 15, 

 and 16, ought to be arranged under Belyta. 



The Plant is Cnicus pratensis (Meadow Plume-thisde.)
