BRITISH CISSID BEETLES. 89 



C. HisPiDus Payk. 



Pubescence usually bvight reililish, but I have seen specimens 

 with yellow or white pubescence. 



Common and widely distributed thi-oughout England. 



I have never seen it in the Isle of Wight. 



Taken in Scotland at Nethy Bridge (Beare) and Garve in Ross- 

 shire (Dr. Joy). 



Ireland : Maryborough (W. E. Sharp), 



C. BIDEXTATUS 01. 



This species is sometimes abundant in a large fungus on old 

 elms, which also pi-oduces Dacne rufifrons and Mycetopliagihs 

 multipunctatus. 



Common n,nd widely distributed tlu'oughout England. 



Scotland : Rannoch, in an old Polyporus on birch, also in- 

 habited by G. nitid'its, C . jacqitemarti, and Bolitophagiis reticulatus 

 L. (Donisthorpe). 



Ireland : Armagh and Dublin. 



I have not seen it in the Isle of Wight. 



C. DEXTATUS Mell. 



Mr. Donisthorpe lias withdrawn this species from the British 

 list (Ent. Record, vol. xxviii. p. 155, 1916). 



C. ALNi Gyll. 



The specimen recorded as C. dentatus Mell. (Ent. Record, 

 vol. xix. p. 136, 1907) is a curious aberration of (J. alni with 

 abnormally coarse punctation of the thorax. 



There appears to have been some interruption of the joigment 

 which gives tlie insect a strange greenish opaque appearance, 

 only the scutellum having the noinial dark brown colour. 



Whilst withdrawing C. dentatus from our list, Mr. Donisthorpe 

 proposes the name of var. mitfordi for this aberration of C. alni. 

 For reasons already stated in connection with 0. boleti, I am not 

 following Mr. Donisthorpe in this direction. 



This species appears to be common in most districts where 

 elders are growing. It occurs unde^" the bark of dead elder- 

 stems upon which the curious black "Jew's ear" fungus is 

 growing. It has been recorded in fungus on oak in Dunham 

 Park, Manchester, and Professor Beare tells me he has taken it 

 plentifully in fungus on dead birch boughs at Nethy Bridge in 

 Scotland. 



CaTbourne, I. of Wight (Mo)-ley), Sando.wn (Mitford). 



There appears to be only one Irish record, from Mote Park, 

 Roscommon. 



C. LATIFRONS, Sp. 11, 



Black, elongate, parallel-sided, clothed with white outstanding 

 pubescence, which, when examined under a lens, is very distinct
