210 SERRICORNIA. [ Cis. 
the side border 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 abietinus on Scotch fir; rare; Scotland, Forth, Tay, Dee, and Moray 
districts (Braemar, Aviemore, &c.); Dr. Power has found it in some numbers at 
Balmuto, Fifeshire, 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. pygmezus, Marsh. (oblongus, Mell.). Elongate, cylindrical, 
black or fuscous black, moderately shiny, clothed with rather strongly 
marked and somewhat long shining greyish pubescence ; antenn 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 anda half times as long as thorax, finely and 
thickly punctured ; legs ferruginous, with the femora and part of the 
tibie often darker. L. 14-25 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, Dulwich, 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. festivus, Panz. Oblong, cylindrical, moderately shiny, of an 
obscurely ferruginous colour, sometimes brown or pitchy brown, clothed 
with rather short and close yellowish pubescence ; antenne 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, &¢.; 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. vestitus, Mell. Allied to the preceding, and closely resembling
