sated, and by its more ovate form ; " it must be admitted that some of 

 tin* diameters given are unsatisfactory, and appear to vary somewhat in 

 different specimens of E. mollis. L. 3-4 mm. 



In pines uud fir trees; very rare; Stephens] records it aa taken in Scotland by Mr- 

 Wilson, anil at Peullegure, Swansea, by Mr. Dillwyn ; in Dr. Power's collection 

 there is a specimen tiiki-n by Turner at Alvie, near Forres, in 1866, which is referred 

 to the species ; but, although it does not agree with E. mollis, I hardly think that it 

 belongs to E. abietit. 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 events, 

 it requires wore continuation. 



E. nigrrinua, 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, 

 antennae 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 9-1 1 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 antenna? 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 Ocliina 

 does not occur in the North American fauna; the chief difference 

 appears to lie in the formation of the antennae, which are serrate or 

 pectinate, and, in the male of Ptilinus, flabellate; if we exclude ffedobia, 

 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 by a single species, are found in Britain; Lasiodcrma serricorne, 

 however, is very doubtfully indigenous.
