legs thk'kemd M. ABBNABIA, P. 



1 1. Thorax strongly rugose ; colour always rufous ; posterior 

 legs thickened .K. ur K A, I'. 



SI. sabnleti, Payk. Oblong, subparallel, black or pitchy Mack or 

 brownish, not very shining, upper surface convex but with disc of elytra 

 subdepressed ; head punctured behind, rugose or slightly granulate in 

 front, antennae and palpi red, maxillary palpi with the last joint slender 

 and acuminate; thorax about as broad as elytra, scarcely narrowed in 

 front, very coarsely punctured, with the base sinuate on each side ; 

 elytra with very strong crenate striae ; legs ferruginous, or pitchy with 

 tarsi lighter, posterior tibiae narrow and only a little widened at apex, 

 posterior tarsi rather long. L. 3-4 mm. 



On the candy banks of rivers and streams both near the coast and inland ; local ; 

 it has not occurred, apparently, in the London district or the south of England ; 

 Bristol; Swansea; banks of Usk; Bewdley ; Matlock ; banks of Bollin, Cheshire; 

 banks of Irwell and Mersey ; Scarborough ; New Brighton ; Northumberland anil 

 Durham district; Scotland, local, Sol way, Forth, Tay, Dee, and Moray districts. 



SI. arenaria, F. (ghbosa, Kug.). Strongly ovate, very convex, 

 somewhat globose, short and broad, of a shining black or reddish-brown 

 colour, with long yellowish or brownish hairs at sides; head convex, 

 thickly granulate in front, antennas yellowish -red; thorax short, trans- 

 verse, extremely finely and almost invisibly punctured, smooth; elytra 

 strongly convex and much dilated behind, with fine and rather feeble 

 striae, which are very obsoletely punctured, interstices broad and smooth; 

 legs ferruginous, posterior tarsi very short, tibiae dilated. L. 4-4-J- mm. 



Sandy coasts ; somewhat local in places, but apparently generally distributed around 

 the coasts of the whole kingdom, and, as a rule, one of the commonest of the sand-liill 

 beetles ; it is extremely sluggish in its movements ; immature specimens are often 

 quite rufous, and in some collections have been made to do duty for M. rufa. 



Si. rufa, F. Oblong, rather elongate, subparallel and almost 

 subcylindrical, elytra somewhat depressed on disc, colour entirely rufous 

 or light ferruginous; head rugose and finely and very thickly granulate, 

 antennae and palpi yellowish-red, last joint of maxillary palpi somewhat 

 securiform; thorax about as broad as elytra, somewhat narrowed in front, 

 coarsely wrinkled, and finely punctured between the wrinkles; elytra 

 strongly striato, the striae being feebly crenate or punctate at their lu.-.-: 

 legs rufous, intermediate and posterior tibiae darker at apex, and much 

 dilated, tarsi short. L. 3f ~H mm. 



On sandy coasts ; very local ; first taken by Mr. P. Archer in June 1862 at New 

 Brighton, and for a long time considered one of our rarest British beetles ; it has, 

 however, been recently taken in some numbers by Dr. Ellis, Mr. Wilding, and other* 

 at Wullasey (Cheshire), Liverpool, and New Brighton, and probably occurs in other 

 localities in the Liverpool and Lancashire district. 



The late Mr. Garneys had a specimen in his collection which, as far as 

 I remember, he told me he captured at Barmouth, North Wales.
