BRITISH CISSID BEETLES 



91 



C. vestttus Mell. 



A variable species, of which I have seen the following 

 combinations : — 



Body black, with pale testaceous clubs of antenna?, Wellington 

 (Power). Black, with black clubs ; pale testaceous, with black 

 clubs ; as well as unicolorous brown and smoky-yellow forms. 

 I have never found C. vestitus and C. festivus inhabiting the 

 same fungus together. 



Forest Hill, Dulwich ; Olton and Sutton Park, Staffs. ; Man- 

 chester district ; Teesdale ; Epping Forest (Beare). Richmond 

 Park (Donisthorpe). 



I have bred it in plenty from fungus scraped from the under- 

 side of dead oak boughs from Enfield, Edmonton, Brockenhurst, 

 and Sanclown, I. of Wight. Widely distributed and not un- 

 common, but often overlooked or mistaken for C. festivus, with 

 which I have seen it confounded in the Power and other 

 collections. 



Not recorded from Scotland or Ireland. 



C. festivus Panz. 



Clubs of antennae always pale. Little or no variation in 

 mature specimens. 



Common and widely distributed in England and in I. of Wight. 

 Usually found in fungi on oak posts or branches. Prof. Beare 

 finds it every year with C. ahii, in fungus on birch branches or 

 faggots at Nethy Bridge. I have bred it in plenty from fungi 

 from New Forest, Godalming, and Portsmouth district, but never 

 in company with any other Cis. 



Ireland (Boris); Queenstown (J. J. Walker). 



C. castaneus Mell. —fuscatus Mell. 



The exchange list of British Coleoptera, Newbery & Sharp, 

 1915, shows the type-form of this species as not yet recorded 

 from Britain. 



This form actually represents the mature insect, which I have 

 bred in great numbers from fungi from Enfield, Epping Forest, 

 New Forest, Warlies Park, Essex, and Sherwood Forest. Rich- 

 mond Park (Donisthorpe) ; Symonds Yat, Cardiff Cannock Chase, 

 and Liverpool in a flour mill (Tomlin). 



Immature specimens were called C. fuscatus by Mellie = 

 fuscatus Mell. = var. fuscatus Newbery &, Sharp, nec Mell. 



C. ELONGATULUS Gyll. 



First mentioned as British by Dr. Sharp (Ent. Mo. Mag. 

 vol. viii. p. 83, 1871), who says Mr. Crotch considers he has 

 Scotch examples of this species. 



Dr. Sharp does not mention having seen the specimens. 



There is a single specimen of a Cis in the Crotch Collection at 

 the University Museum, Cambridge, standing in the name of
