424 RHYNCHOPHORA. [Phleophthorus. 
Scolytide ; short and comparatively broad, convex, pitchy-blaek, dull, 
with rather scanty but distinct greyish pubescence, base of antenne, 
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 cn disc, subgranulate at sides ; 
elytra deeply crenate-striate, interstices raised, subcarinate, furnished 
with rather short, erect, rigid sete, which are arranged in more or less 
distinct rows ; in the male the forehead is excavated. L. 13-1} mm. 
In dead stems of furze, broom, &c.; local, but, as a rule, not uncommon where it 
occurs ; Shirley, Reigate, Mickleham, Woking, Birch Wood, Wimbledon, Darenth, 
Coombe Wood, West Wickham, Dartford, Chatham, Sheerness, Rusper, Southend, 
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. 
POLYGRAPHUS, 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 antenne springs (not of the forehead, as stated by Redtenbacher) ; 
by the third joint of its tarsi not being wider than the preceding; by 
the club of the antenne 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 coxe 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 fir. 
P. pubescens, Bach. (polygraphus, L.). Oblong, subcylindrieal, 
slightly shining, black, brown, or yellow brown, clothed with squamose 
pubescence, antenne 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 striz, clothed with scanty scale-like 
pubescence and very short sete; the species resembles SHylastinus 
obscurus, but the sculpture will easily separate it and also the fact that 
the tibie 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 (R. Lawson); the Polygraphus 
pubescens of Stephens (Manual, 206) appears to be Pityophthorus micrographus.
