C. ATEATULTJM, Reittei'. 



Yery like C. ferrugineum, but quite black, antennae black, with the apex of the 

 last joint pitchy ; elongate, parallel-sided, depressed ; thorax longer than broad, 

 parallel-sided, with a slight prominence or sinuation on each side-margin just at be- 

 ginning of posterior third ; this is not very marked, and is not so distinct in the 

 actual specimen as in Reitter's plate {I. c.) : the elytra are oblong, with two indistinct, 

 broad impressions towards base, with rather deep punctured strise, which are continued 

 to apex or nearly to apex ; legs black. Long., 2 mm. 



Under beeeh-bark : two male specimens found by Plerr Reitter in 

 North-east Hungary, in a mountainous district. 



C. FEREUGINEUM, Steph. {anqustatum, Er.). 



Rufo-ferruginous, oblong, parallel-sided ; smaller and narrower than C. histeroides 

 to light specimens of which species it bears a considerable resemblance : thorax 

 rather strongly punctured, thickly at sides, less thickly on disc, in male a little longer 

 than broad, very slightly widened in front, in female evidently longer than broad, 

 parallel-sided, basal impressions distinct but not large : elytra with sides a little 

 rounded, with rather strong punctured strise, which, at sides, are more or less 

 evanescent towards apex, first interstice next suture with a row of very fine punc- 

 tures : sutural stria evidently deepened at apex. Long., 2-2? mm. 



Common throughout North and middle Europe under bark o£ all 

 kinds of deciduous trees, especially beeches : local in England, but 

 widely distributed. Cobham Park, Kent, New Eorest, Dean Forest, 

 Cannock Chase, &c. ; Scotland, Rannoch, Aviemore, &c. 



C. IMPEESSUM, Er. 



Exceedingly like the preceding but a little more depressed and broader, with the 

 thorax especially broader, being almost quadrate in the male, and quadrate in the 

 female ; in the former sex it is slightly transverse, and has the sides feebly dilated 

 and rounded in front ; the basal impressions are much larger, and the striae of the 

 elytra are mai'kedly stronger ; they become feebler behind but i-each the apex, or very 

 nearly so ; the sutural stria is evidently deepened at apex. Long., 2-2j mm. 



A rare species in central and southern Europe : it does not appa- 

 rently occur in Britain ; it appears, however, to vary as regards size 

 of basal impressions, &c., and I have a variety, from the Morea, in 

 ■which these impressions are quite small as compared with the type- 

 form ; I have seen specimens from Aviemore and the Dean Forest 

 which are somewhat intermediate forms, but I have never seen a 

 typical British specimen of impressum, and would refer these specimens 

 \o ferrugineum : there is so much difficulty attached to these last three 

 species of the genus, that it is only on quite typical forms that a 

 species should be introduced as indigenous.
