Snprinus.] CLAVICORNIA. 211 



tion somewhat diffuse ; striae punctured ; sutural stria often more or less 

 obsolete and as a rule not joining fourth dorsal stria ; pygidium thickly 

 punctured ; antennas and legs black, tarsi somewhat reddish, anterior 

 tibiae with 8-9 teeth. L. 4-5 1 mm. 



In carcases, dung, &c. ; generally distributed and common throughout England and 

 Wales, and probably Ireland ; it appears, however, to be local in Scotland, Lowlands, 

 Solwny and Forth districts. 



S. aeneus, F. Black, shining, slightly aeneous ; forehead rather 

 thickly punctured ; thorax thickly punctured at sides, and with two or 

 three uninterrupted rows of larger punctures at base, disc smooth ; elytra 

 closely punctured with the sides and shoulders and a common space 

 towards base smooth ; this space is traversed by the fourth dorsal stria, 

 and the part outside the stria reaches as far longitudinally as the part 

 between this and the sutural stria ; striae punctured ; sutural stria, as a 

 rule, joining fourth dorsal stria ; pygidium thickly punctured ; antennae 

 and legs black, anterior tibiae with 8-10 small teeth. L. 3-4 mm. 



In carcases, dung, &c. ; as a rule considered common and generally distributed 

 throughout the greater part of England; it is, however, local in Scotland, in the 

 Solway, Forth, and Moray districts, and is not common in some localities in Eng- 

 land ; at Hunstanton, Norfolk, for instance, where I have found other members of 

 the genus in numbers, I have never taken a specimen of 8. <enevs. Ireland, mar 

 Belfast and Dublin. 



S. immundus, Gyll. This species bears a considerable resemblance 

 to the preceding, but may easily be distinguished by its darker and less 

 metallic colour, and by the much closer punctuation of the elytra, which 

 covers the whole of their upper surface except the shoulders and a space 

 towards base, which is traversed by the fourth dorsal stria ; the space, 

 however, outside the stria is small, and abbreviated in front and behind 

 by punctuation ; the sutural stria, is said by some authors to be separated, 

 from the fourth dorsal stria, and this is given sometimes as a character, 

 but in this respect the species is very variable, and I have specimens in 

 which the sutural stria on one elytron joins the dorsal stria, and on the 

 other is separated from it ; legs pitchy, anterior tibia? with 7-8 teeth, 

 which are somewhat larger than in S. ccneus. L. 3-4 mm. 



In dung ; local and usually considered rare ; Deal ; Camber sand-hills, near Hastings, 

 somewhat common ; Wales ; Southport ; Lancaster sands ; Hunstanton, Norfolk, in 

 numbers ; in this latter locality I have found it by far the commonest of the genus ; 

 the species appears to occur mainly on sand-hills near the coast. 



S. virescens, Payk. Shining, metallic green ; antennas black ; 

 forehead, thickly punctured ; thorax distinctly punctured through- 

 out, a point that will at once separate it from all our other species, 

 punctuation more close at sides ; elytra rather strongly punctured over 

 their whole surface except round scutellum, and at shoulders ; dorsal 

 striaa extending a little beyond middle ; pygidium thickly punctured ;
