BRITISH CISSID BEETLES. 87 



C. NiTiDus Herbst. 



Common and widely distributed thi'ougbout Britain. 

 Ii-eland, common in Dublin and Belfast districts. 

 It is found in Scotland in company witb C . jacqioemarti MelL, 

 and is sometimes confounded witb tbat species in collections. 



C. JACQUEMARTI Mell. 



Previously only recorded from Scotland, wbere it has been 

 taken freely at Rannocb (Turner, Beare, and Denistborpe), 

 Garve in Ross-sbire (Dr. Joy). Near Brockenburst, 1915 

 (Dr. Sbarp), in company witb C. nitidus Herbst. 



Not recorded from Ii'eland. 



C. BiLAMELLATUS Wood = MlcmieUcittis Fowler (Europ. List 

 Heyden, Reitter & Weise, 1906) = mimtius Blackburn. 



Tbere is some considerable variation in size and development 

 of tbe males. Small specimens occur witbout tbe uprigbt plates 

 on tbe tborax and clypeus, wbicb migbt easily be mistaken for 

 females or for members of anotber species. 



Additional localities : Orpington, Kent (Pool), Eicbmond Park 

 (Donistborpe & Perkins), Higbgate (Janson). 



It bas occurred at Port Lincoln, Soutb Australia, and was 

 named C. minutns by Blackburn, witb wbose type I bave 

 compared Britisb specimens. 



Exceeding abundant in Kent and Surrey, but is probably an 

 introduction like tbe following species. 



C. LINEATOSETOSUS, Sp. n. 



Sbort and broad, unicolorous testaceous, sbiny. Head smootb, 

 finely punctured and pubescent. Tborax finely punctured and 

 pubescent, sligbtly narrowed in front, front mai'gin witb two 

 indistinct teetb wbicb merge witb two otber more distinct teeth 

 on tbe clypeus when viewed from behind. Elytra twice as long 

 as thorax, broad, closely punctured, especially near tbe scutellum, 

 and clothed with ten straight rows of erect setae. Legs and 

 antennte entirely pale testaceous. 



Length 1| mm. 



This insect resembles tbe small undeveloped males of G. hila- 

 niellatus, wbicb bear only slight traces of tbe plates on the thorax 

 and clypeus. It is not an indigenous species, but because of its 

 long residence in London and tbe possibility of its having become 

 established in our parks or woods, it is desirable that its origin 

 should be recorded with these notes on species found in Britain. 



Several specimens are in Bi'itisb collections, which I bave 

 traced to tbe following source : — 



" 86. In a fungus from the South Sea Islands that had been 

 many years in Mus. Brit, (alive). From W. Oarrutbers, Esq., 

 Sept. 1866." 



I am indebted to Mr. J. N. Halbert of tbe National Museum,
