Si/Dcalt/pta.'] CLAVicoRNiA. 3G7 



I. Thorax rather thickly and finely puuctured. 



i. Size smiiUer ; elytra with one deep marginal stria com- 

 plete ; erect setae shorter S. SPINOSA, Rossi. 



ii. Size larger ; elytra with two deep marginal striiB 



complete; erect setae longer . . S. SETIqera, 7J/. 



II. Thorax coarsely punctured S. uiksuta, Sharp. 



S. spinosa, Eossi {arenaria, Sturm). Subglobose, narrowed in 

 front and behind, strongly convex, black, dull, without scales, but with 

 stout upright whitish bristles on the upper surface, which are more 

 thickly placed at the apex of the elytra ; antennae reuilisli-brown ; fore- 

 head with two diverging furrows ; thorax thickly and finely punctured, 

 very transverse ; elytra with rows of rather large punctures which 

 become feebler behind, with one deep marginal stria complete ; under- 

 side coarsely punctured ; legs black or pitchy-black. L. 1^ mm. 



In chalky places, at roots of grass, iu moss, &c. ; local, but often in abundance 

 where it occurs ; London district, widely distributed, Chatham, Micklehtim, Cater- 

 ham, Warlingham, Cuxton, Uigham, Faversham ; Folkestone; Hastings; Portsmouth; 

 Norfolk; Suffolk ; Swansea. 



S. setigrera, III. Larger than the preceding, strongly convex, 

 black, the upper-side more or less distinctly clothed with scales, variegated 

 with white, with long black erect somewhat clavate setae, which are 

 placed more thickly at the apex of the elytra ; thorax rather thickly and 

 finely punctured, much narrowed in front ; elytra striate, with ivfo deep 

 jnarginal striie complete ; nnder-side and legs thickly punctured, the 

 latter usually reddish-brown. L. 2| mm. 



At roots of grass, in moss, &e. ; according to Dr. Sharp, the true S. setigera has 

 only occurred iu Scotland, where it is found very rartly in the Solway district at 

 Caerlaverock, near the mouth of the Nith ; the specimens standing under the name 

 in our collections must be referred to the succeeding species. 



S. hirsuta, Sharp. Closely allied to the precedingj but with much 

 more coarsely punctured thorax, lighter-coloured antennce and legs, 

 lighter-coloured, longer, thinner and less clubbed sette, and the depressed 

 scale-like hairs on the thorax much longer ; the depressed scales on the 

 elytra also appear to be much less numerous and distinct than in setigera, 

 and not variegated as in that species ; as a rule, however, these are 

 more or less rubbed off in most specimens of both insects, unless they 

 are captured when quite fresh. L. 2| mm. 



Chalky places, at roots of grass and plants, in moss, &c. ; local, but occasionally 

 abundant; Mickleham, Chatham, Sheerness (in profusion, J. J.Wi.lker), Faruborough ; 

 Deal ; Hastings ; Seaford, Devon, at roots of Flanlago ; Norfolk; Suffolk; Hereford; 

 Swansea. 



BVRRKVS, Linne'.* 



This genus contains about forty species, of which nearly twenty occur 



* According to Reitter (Bestimmungs Tabellen IV. Cistelidse, &c., p. 6) this genus 

 is synonymous with Cistela, Geoffroy.
