Cytilus.'] OLAVICORNIA. 871 



C. varius, F. (sericeus, Forst. ; pulchellus, Heer.). Short oval, very 

 convex, of a dark bronze or greenish metallic colour, clothed with short 

 pubescence ; head thickly and deeply punctured, with rather thin black 

 pubescence variegated with yellow and sometimes with white ; thorax 

 thickly punctured, much narrowed in front, with pubescence much as 

 on head ; elytra finely striated, usually greenish, with the alternate 

 interstices more shining and variegated with velvety-black ; the first, 

 third, and fifth interstices are usually more or less golden ; under-side 

 and legs black, frosted with short whitish pubescence. L. 4-5 mm. 



Damp places, in moss, at roots of grass, &c. ; somewhat local but not uncommon 

 and generally distributed throughout Englun 1 and Wales ; Scotland, common, Solway, 

 Forth, Clyde, Tay, Dee, and Moray districts ; Ireland, Galway, Donegal, Portmar- 

 nock, &c., and probably common. 



ItXORVCHUS, Erichson (Pedilophorus, Steffahny). 



About a dozen species are contained in this genus, one of which has 

 been recorded from South Africa, but the remainder have occurred in 

 Europe, Northern and Central Asia, and North America ; they may be 

 distinguished from Cytilus by their free mandibles and the absence of 

 elytral striae ; our single species may be easily recognized by its elongate 

 oval, somewhat oblong, form, and the long and thick white pubescence on 

 the scutellum. 



IMC. aeneus, F. Oblong-ovate, more elongate than any other British 

 member of the family, convex, shining metallic bronze or greenish-bronze ; 

 antennae black ; head large, rather closely covered with whitish pubes- 

 cence ; thorax convex, narrowed in front, distinctly punctured, rather 

 thinly pubescent ; scutellum thickly covered with long white hairs ; 

 elytra somewhat strongly punctured, rather thickly pubescent at sides, 

 more sparingly on disc ; under-side thickly punctured, clothed with thick 

 greyish pubescence ; legs pitchy-black or pitchy-brown. L. 4-4^ mm. 



In sandy barren places on the banks of streams and on the coast ; local and chiefly 

 found in the north of England and in Scotland; sometimes very abundant where it 

 occurs ; Northumberland and Durham district, rare, Langleyford, and on the banks of 

 the Irthing ; Holy Island ; Scotland, local, Solway, Forth, Clyde, Tay, Argyle, Dee, 

 and probably other districts ; Ireland, Galway. 



SIMPLOCARIA, Marsham. 



This genus comprises a few species, the greater number of which 

 occur in Europe, and two or three in Northern Asia and North America ; 

 together with Morychus (Pedilophorus) and Ampliicyrta they form Lr. 

 Horn's tribe the Amphicyrtina, which is distinguish' d from the Byrrhina 

 by having the epistoma short, but distinct, and coriaceous, whereas in 

 the last-named tribe there is no distinct epistoma ; the species of Sim- 

 plocnria are small, oval, convex insects, and may be known by having
