NORTHUMBERLAND AND DURHAM. 35 



Manual, No. 3122. — Raphirus nigricornis, Holme, Trans. 



Ent. Soc. Loud., iii., 127? 

 About the size of large specimens of Q. Boops, more of the habit 

 of Q. attenuatus; the head less than in Q. Boops, and the eyes 

 scarcely prominent. Black, shining ; head, thorax, and scutellum 

 polished and shining, nigro-seneous ; elytra also shining, piceous, 

 subteneous. Antennce longer than in Q. sciutillans, not quite so 

 long as the head and thorax, slightly thickened towards the apex, 

 third joint scarcely thinner and very slightly longer than the 

 second, the rest gradually shortening, and somewhat thicker, ninth 

 and tenth nearly transverse, the last largest, obliquely truncate 

 and acuminate at the apex beneath; dask fuscous, the basal joint 

 beneath, and the base and apex of the three first joints above 

 ferruginous. Palpi fuscous, apical joint acute. Mouth piceous. 

 Head about the size of that of Q. attenuatus, narrower than the 

 thorax, rotundate, rather convex, with four small but deepish 

 punctures placed transversely between the eyes, of which the 

 inner is close on the margin itself, and two larger placed obliquely 

 behind the eyes on each side, of which the largest is nearest the 

 eye; sides behind the eyes extremely finely punctulate. Eyes 

 large, scarcely prominent, nearly in the same arc as the sides of 

 the head. Thorax rather narrower than the elytra, convex, some- 

 what narrowed, compressed, and deflexed at the anterior angles, 

 the length about equal to its breadth at the base, sides slightly, 

 base and posterior angles strongly rounded ; dorsal series of three 

 small oblique punctures, of which the two posterior in each row 

 are placed very near, more approximating than in other species, 

 before the middle of the disk, the anterior smallest, rather 

 approaching the apex, and situated nearer the second, than the 

 first, or all nearly equidistant; then outwards are two minute 

 punctures on each side, placed in a line, and rather apart; then 

 two deep approximating punctures towards the anterior angles, 

 and one within, close upon each angle. Scutellum polished and 

 smooth. Elytra about the length of the thorax, widest towards 

 the apex, slightly convex above, depressed along the suture, 

 more deeply at its apex, strongly, somewhat thickly, but not quite 

 closely punctate, thinly griseous pubescent, shining piceo-seneous,
