it in general appearance and colour ; it is, however, smaller, narrower 

 ami 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 antennae, moreover, are darker, 

 : illy 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. fu^catus. L. 1-lf mm.

 Park, near Birmingham ; Repton ; Duuham Park aud other localities near 

 Manchester; Teesdale. 



C. fuscatus, Mell. (castanevs, Mell. ;faffi, Waltl.). Rather elongate 

 and narrow, somewhat depressed on disc, ferruginous or brownish-red, 

 clothed with greyish pubescence ; antennae 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 witli the clypeus armed with two tubercles. 



In boleti, fungoid growth on trees, &c. ; local ; Highgate ; Richmond Park ; 

 Chertsey ; New Forest; Canuock 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- 

 cylindrical, of a fuscous or fusco-testaceous colour, scantily clothed 

 with yellow pubescence ; head slightly rugose, with the eyes prominent, 

 antennae 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. 1^-2 mm. 



Mule 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 ; clypeus 

 and thorax without plates. 



In boleti nnd under bark ; on pine, birch, and ash; very local ; taken in prof union 

 at West Wickham Wood, near London, by Mr. T. Wood in 1884 ; it has not, how. 

 ever, been recorded from any other locality, t-itlicr British or foreign ; Mr. W<MH) lias 

 remarked th:it in the mule pupa the luincllic on the clypcus and thorax are us
