Cis. | SERRICORNIA. 211 
it in general appearance and colour; it is, however, smaller, narrower 
and flatter, with the margins of the thorax narrower, and the sides of 
the same more contracted in front, and it may also be known by its 
more closely punctured elytra; the antenne, moreover, are darker, 
especially towards apex; the male has the clypeus furnished with two 
tubercles ; as regards punctuation the species appears to be intermediate 
between C. festivus and C. fuscatus. L. 1-1$ mm. 
In boleti, &e. ; rare; Forest Hill, Surrey (Marsh); Dulwich; Olton and Sutton 
Park, near Birmingham; Repton; Dunham Park and other localities near 
Manchester; Teesdale. 
C. fuscatus, Mell. (castaneus, Mell. ; fagi, Waltl.). Rather elongate 
and narrow, somewhat depressed on disc, ferruginous or brownish-red, 
clothed with greyish pubescence ; antenne red, with the club sometimes 
darker; thorax about as long as broad, with the sides narrowly 
bordered, and all the angles obtuse or rounded, finely punctured ; elytra 
two and a half times as long as thorax, closely and finely punctured ; 
legs ferruginous. L. 1-1} mm. 
Male with the clypeus armed with two tubereles, 
In boleti, fungoid growth on trees, &e.; local; Highgate; Richmond Park ; 
Chertsey ; New Forest; Cannock Chase; Shrewsbury; Church Stretton; Sherwood 
Forest ; Dunham Park, Manchester. 
The narrow depressed form, and fine punctuation, will serve to 
separate this species from its allies. 
C. bilamellatus, Wood. Oblong, rather short and broad, sub- 
eylindrical, of a fuscous or fusco-testaceous colour, scantily clothed 
with yellow pubescence ; head slightly rugose, with the eyes prominent, 
antenne yellow, with the club blackish; thorax closely and finely 
punctured with the spaces between the punctures very finely rugose, 
sides finely margined, posterior angles rounded; at the base there is a 
trace of a smooth central line; elytra about twice as long as thorax, 
rather broad, subparallel, closely but distinctly sculptured, broadly and 
bluntly rounded at apex ; legs testaceous. L. 15-2 mm. 
Male with the clypeus produced into a broad upright plate which is 
somewhat recurved at apex, and with the thorax subquadrate, narrowed 
in front, and with the anterior margin produced into a broad upright 
plate, similar to that on clypeus, but not recurved at apex. 
Female with the thorax longer than broad, with the sides less 
rounded and more gradually contracted in front than in male; elypeus 
and thorax without plates. 
In boleti and under bark; on pine, birch, and ash; very local; taken in profusion 
at West Wickham Wood, near London, by Mr. T. Wood in 1884; it has not, how- 
ever, been recorded from any other locality, either British or foreign ; Mr. Wood has 
remarked that in the male pupa the lamella on the clypeus and thorax are as 
conspicuous as in the imago.
