CV.] BEimiCORXIA. 207 



Mr. Crotch, appears to be only a variety of C. boleti, in which the rugose 

 punctuation of the elytra is more apparent, and the larger punctures 

 more or less obsolete ; as intermediate variations occur, it can hardly be 

 regarded as a stable variety, much less as a species. 



C. villosulus, Marsh, (setiger, Mell. ; plagiatus, Thorns.). Very like 

 the preceding, but smaller and narrower, with the base of the thorax 

 margined, and the impressions on its disc, as a rule, more obsolete ; the 

 colour as a rule is lighter, and the pubescence of the elytra is distinctly 

 stronger and more sparing, and also longer ; the general form is said to 

 be less convex and the side margins of the thorax less pronounced, but, 

 in some specimens at all events these are not marked characters ; the 

 femora are nigro-fuscous at base. L. 2|-3 mm. 



In boleti and fungoid growth ; often under bark of willows, &c. ; locally common ; 

 London district, common and generally distributed ; Dover ; Glnnvilles Wbotton ; 

 Needwood. Staffordshire ; Hepton, Burton-on-Trent ; Dunham Park, Manchester 

 (in boleti on beech), ami Stretford ; it has not been recorded from the northern 

 counties or from Scotland . 



C. xnicans, F. (pyrrocephalus, Marsh.). Oblong, convex, fuscous 

 black or fuscous (in immature specimens lighter), clothed with fine and 

 regular short greyish pubescence, with the antennae and legs ferruginous, 

 the former with the club always dark in mature examples ; thorax with 

 disc even, a little broader than long, finely, thickly, and rather regularly 

 punctured, but not rugose, anterior margin slightly produced, side 

 margins rather broad, posterior angles right angles ; elytra more than 

 twice as long as thorax, finely, rather thickly, and rugosely punctured, 

 witli large punctures intermingled, which are arranged in more or less 

 distinct rows towards base. L. 2-3 mm. 



Male with the forehead impressed and the clypeus emarginate in 

 middle at apex, and furnished on each side with a blunt tooth. 



In boleti, Ac. ; local, and, as a rule, not common ; London district, not common, 

 Mickleham, Rebate, Forest Hill, Hawkhurst, Chatham, Gravesend, Farnliam, West 

 Wickhtun, Loughton, Kusper ; South Devon ; Yardley and Knowle, near Birming- 

 ham ; Repton ; Sherwood Forest. 



C. hispidus, Payk. This species is very closely allied to the pre- 

 ceding, and by some authors, apparentl}', is considered identical with it ; 

 it may, however, be known by the evidently narrower margins of the 

 thorax ; the pubescence is also longer, and the antennae are red, with 

 the club not darker as in C. micans ; this latter character, which was 

 pointed out to me by Dr. Power, seems to be of great use in dis- 

 tinguishing mature specimens of the two species ; mistakes may of 

 course arise with immature ones. L. 2-3 mm. 



In boleti, Ac. ; local, but commoner than the preceding ; London district, Kent 

 and Surrey, not uncommon, and apparently generally distributed ; Essex ; Devon ; 

 Windsor ; Mulvern ; Bowdley ; Cannock Chu-o ; Knowle ; Sherwood Forest ; Rep- 

 ton ; neither this nor the preceding species have occurred further north than the 

 Midland*.
