210 SERRICORNIA. [Ci. 



the side bonier is very fine ; elytra long, two and a half times as long as 

 thorax, closely, strongly, and irregularly punctured, with rather long 

 pubescence ; legs testaceous. L. 2 mm. 



Male with the clypeus emarginate at apex, and a small tooth at each 

 side of the emargination. 



In Polyporus dbietinus on Scotch fir ; rare ; Scotland, Forth, Tay, Dee, and Moray 

 districts (Bracmar, Aviemore, &c.) ; Dr. Power has found it in some numbers at 

 Balmuto, Fifcshire, under bark of larch. 



This species may easily be known from all our other species of Cis 

 by the punctuation and pubescence of the elytra. 



C. pygrmeeuB, Marsh, (oblongm, Mell.). Elongate, cylindrical, 

 black or fuscous black, moderately shiny, clothed with rather strongly 

 marked and somewhat long shining greyish pubescence ; antennae testa- 

 ceous or light ferruginous ; thorax broader than long, a little narrowed 

 in front, with the sides and base finely margined, anterior angles obtuse, 

 posterior angles almost right angles, upper surface evenly and very finely 

 punctured ; elytra two and a half times as long as thorax, finely and 

 thickly punctured ; legs ferruginous, with the femora and part of the 

 tibiae often darker. L. 1|-2| mm. 



Male with the clypeus furnished with a tooth or tubercle on each 

 side. 



In boleti ; also on old stumps, and by beating old trees ; not common ; Chatham, 

 Forest Hill, Horsell, Coombe Wood, Dulwicb, Tonbridge; New Forest; Windsor; 

 Reading ; Knowle, near Birmingham. 



By some authors this species is compared with C. alni, but it is 

 darker and more convex, more strongly pubescent, and more closely 

 and finely punctured ; it is, apparently, very variable in size. 



C. feBtivus, Panz. Oblong, cylindrical, moderately shiny, of an 

 obscurely ferruginous colour, sometimes brown or pitchy brown, clothed 

 with rather short and close yellowish pubescence ; antenna? reddish ; 

 thorax broader than long, finely punctured and pubescent, with the sides 

 slightly rounded, and plainly margined (a character that will distinguish 

 it from the allied species), anterior angles blunt and not projecting, 

 posterior angles obtuse or slightly rounded ; elytra twice as long as 

 thorax, not very closely and rather distinctly punctured, with the inter- 

 stices very finely rugose; legs ferruginous. L. 1-2 mm. 



Male with the clypeus armed with two small erect tubercles placed 

 near one another, and with the thorax almost broader than elytra. 



In boleti, Ac.; also in decaying wood, especially fallen boughs; not common; 

 Chatham, Caterham, Mickleham, Shirley, Whitstable, Esher, Cowfold ; Ulting, 

 Essex; South Devon; Leicestershire; Northumberland and Durham district, Ravens- 

 worth, Wallington, Seghill Dene, and by the Irthing ; Scotland, not common, Tweed, 

 Tay, and Dee districts. 



C. vestituB, Mell. Allied to the preceding, and closely resembling
