Cis. | SERRICORNIA. 207 
Mr. Crotch, appears to be only a variety of C. bolet/, 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, Thoms.). 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 arule 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. 25-3 mm. 
In boleti and fungoid growth ; often under bark of willows, &c.; locally common ; 
London district, common and generally distributed; Dover; Glanvilles Wootton; 
Needwood, Staffordshire; Repton, Burton-on-Trent; Dunham Park, Manchester 
(in boleti on beech), and Stretford; it has not been recorded from the northern 
counties or from Scotland. 
C. micans, F. (pyrrocephalus, Marsh.). Oblong, convex, fuscous 
black or fuscous (in immature specimens lighter), clothed with fine and 
regular short greyish pubescence, with the antenne 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, 
with 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, &c.; local, and, asa rule, not common; London district, not common, 
Mickleham, Reigate, Forest Hill, Hawkhurst, Chatham, Gravesend, Farnham, West 
Wickham, Loughton, Rusper; 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, apparently, 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 antenne 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. 2-8 mm. 
In boleti, &c.; local, but commoner than the preceding; London district, Kent 
and Surrey, not uncommon, and apparently generally distributed ; Essex ; Devon; 
Windsor; Malvern; Bewdley ; Cannock Chase ; Knowle ; Sherwood Forest; Rep- 
ton; neither this nor the preceding species have occurred further north than the 
Midlands.
