sated, and by its more ovate form;” it must be admitted that some of 
the characters given are unsatisfactory, and appear to vary somewhat in 
different specimens of #. mollis. L. 3-4 mm. 
In pines and fir trees; very rare; Stephens| records it as taken in Scotland by Mr: 
Wilson, and at Penllegare, Swansea, by Mr. Dillwyn; in Dr. Power’s collection 
there is a specimen taken by Turner at Alvie, near Forres, in 1866, which is referred 
to the species; but, although it does not agree with Z. mollis, I hardly think that it 
belongs to H. abéetis. Dr. Sharp omits it entirely from his Scottish list, and I think 
that it is quite possible that we do not possess the true species as British ; at all eveuts, 
it requires more confirmation, 
E. nigrinus, Sturm. Elongate, subcylindrical, of a black or pitchy- 
black colour, clothed with fine greyish pubescence, palpi and tarsi rufous; 
the tibia also are often reddish; head large, with eyes prominent, 
antenn pitchy, with base lighter, longer than half the body, with joints 
5-8 very small, transverse (a point that will at once distinguish 
the species), joints 9-11 long; thorax broader than long, narrowed in 
front, rather narrower at base than elytra, finely and closely punctured, 
with a more or less distinct central furrow, posterior angles rounded ; 
elytra long, parallel-sided, closely and finely punctured; legs slender, 
fifth joint of tarsi double as long as fourth; varieties occur in which the 
elytra are fuscous-brown or reddish-brown. L. 3-4 mm. 
On Scotch fir; local in the Highlands of Scotland, Tay, Dee, and Moray districts ; 
it is sometimes common where it occurs; it was one of Charles Turner’s captures, 
although one specimen existed in Mr. Crotch’s collection, without locality, before he 
found it; this specimen was formerly in Mr. Wollaston’s collection. 
XYLETININA. 
Dr. Horn (Classification of the Coleoptera of North America, p. 225) 
remarks that the members of this tribe differ from those of the preceding 
only by the antenne being curved around the under surface of the head 
in repose, instead of being extended straight along the middle of the 
body; he does not, however, include the genus Ptilinus, and Ochina 
does not occur in the North American fauna; the chief difference 
appears to le in the formation of the antenne, which are serrate or 
pectinate, and, in the male of Pézlinus, flabellate; if we exclude Hedobia, 
which by some authors is included in the tribe, the Xyletinina contain 
nine European genera and thirty-five species, of which four genera, each 
represented bya single species, are found in Britain; Lasioderma serricorne, 
however, is very doubtfully indigenous,
