424 RHYNCHOPHORA. \_Plilceoplitlwnit. 



Scolytidee ; short and comparatively broad, convex, pitchy-black, dull, 

 Avith rather scanty but distinct greyish pubescence, base of antenna?, 

 and the tarsi, testaceous ; head finely punctured ; thorax subtransverse, 

 with the sides gradually and not strongly narrowed in front, rather 

 finely and not very closely punctured en disc, subgranulate at sides ; 

 elytra deeply crenate-striate, interstices raised, subcarinate, furnished 

 with rather short, erect, rigid setae, which are arranged in more or less 

 distinct rows ; in the male the forehead is excavated. L. 1^-lf mm. 



In dead stems of furze, broom, &c. ; local, but, as a rule, not uncommon where it 

 occurs ; Shirley, Keigate, Mickleham, Wokiug, Birch Wood, Wimbledon, Darenth, 

 Coornbe Wood, West Wickham, Dartford, Chatham, Sheerness, Rusper, Southern!, 

 Whitstable ; Eastbourne; Southsea; Shirley Warren, Southampton; New Forest; 

 Monmouthshire and Herefordshire, abundant ; Bewdley Forest ; Liverpool district ; 

 Scarborough ; Northumberland and Durham district ; Scotland, scarce, Tweed, 

 Forth, Tay and Moray districts ; it almost certainly occurs in Ireland. 



POXiYGRAPHUS, Erichson. 



This very distinct genus is easily separated from all our other 

 Hylesinina by the fact that each of its eyes are almost entirely divided 

 into two parts, through an encroachment of the lateral piece from which 

 the antennae springs (not of the forehead, as stated by Itedtenbacher) ; 

 by the third joint of its tarsi not being wider than the preceding; by 

 the club of the antennae not being articulated ; and by the five-jointed 

 funiculus; the club, moreover, is very large, flattened, and ovate, and 

 considerably longer than the funiculus. The anterior coxa; are very 

 close to each other, and the intermediate pair are widely separated (Ent. 

 Monthly Mag. viii. 82) ; two species are known, one occurring in 

 Europe and the other in Canada and Alaska ; the former of these has 

 been found very rarely in Britain ; it appears to live under bark of fir, 

 especially spruce iir. 



P. pubescens, Bach, (polyyraphus, L.). Oblong, subcylindrical, 

 slightly shining, black, brown, or yellow brown, clothed with squamose 

 pubescence, antenna? and legs pale ; thorax transverse, thickly and very 

 finely punctured, somewhat compressed at apex, with a fine raised 

 central line ; elytra delicately and confusedly and very closely granulose- 

 punctate, with indistinct traces of strise, clothed with scanty scale-like 

 pubescence and very short setae ; the species resembles Hylastinus 

 olscttrus, but the sculpture will easily separate it and also the fact that 

 the tibiae are in a much less degree and less abruptly dilated, and are 

 only slightly denticulate-serrate on their outer edge. L. 2-3 mm. 



In the male the forehead is clothed with thick pale villose pubescence, 

 and in the female the forehead is more sparingly pubescent. 



Under fir bark ; very rare ; near Scarborough (K. Lawson) ; the PolyyrapJms 

 pubescens of Stephens (Manual, 20G) appears to be Pityophthorus microyraplius.
