Olilrus.'] CLAVICORNIA. 153 



O. millefolii, Payk. A small species, oval, very short and strongly 

 convex, subglobose, deep black, very shining ; head very finely punc- 

 tured, antennae sometimes yellow, sometimes dusky yellowish, with the 

 club and sometimes the first joint brownish, palpi black ; thorax impunc- 

 tate, with the base slightly sinuate on each side near scutellum, posterior 

 angles right angles ; elytra with the two striae near suture well marked, 

 the other striae very fine and very finely punctured, interstices extremely 

 finely punctured ; under- side clothedwith thin greyish pubescence; legs 

 sometimes black, but often lighter, and sometimes even yellowish, second 

 joint of anterior tarsi considerably dilated in male. L. 1^-lf mm. 



By sweeping ; on flowers of Achillea millefolium ; Claygate, Caterham, Lee, 

 Horsell, Southend ; Brandon, Suffolk ; Horning Feu ; Kingsgate ; Devon, Exniouth. 



Examples of this species with dark antennae are very like small speci- 

 mens of 0. (emus, but may be distinguished by having no greenish 

 metallic tinge on the elytra, and by the more convex and shorter oval 

 form which is less narrowed behind, 



O. pyg-maeus, Sturm. Elongate-oval, strongly convex, black, 

 shining, usually pitchy towards apex ; antennas yellow or brownish- 

 yellow ; palpi brownish-red ; thorax as in the preceding species, but 

 with the posterior angles obtuse ; elytra with the two striae near suture 

 distinct, and with traces of other strise, interstices extremely finely 

 punctured ; under-side pitchy-brown, legs reddish-brown ; very closely 

 allied to 0. millefolii, but distinctly more elongate and narrower, with 

 the posterior angles of thorax not right angles, and the elytra pitchy 

 towards apex. L. 1-1-^ mm. 



By sweeping; not common ; Darenth Wood, Shirley, Caterham, Aslitead, Woking, 

 Cobham ; Weybridge; Athwickeu ; Horning Fen; Wickham and Bui-well Fens; 

 Cromer; Ipswich. 



In L'Abeille, 1885, Clavicornes, p. 13, the localities for 0. ulicis, 

 Gyll., are given as " Suede, Angleterre ;" the species, however, has not 

 been recognized as from England by British Entomologists ; it appears 

 to be closely allied to 0. cenevs, but nearly as small as 0. pygmaeus, from 

 which it differs in its less ovate and elongate form, and the more distinct 

 metallic reflection of its elytra ; it is smaller, shorter, more convex and 

 less metallic than 0. census. 



S TIL BUS, Seidlitz. 



This genus has usually been included under Olilrus, but is distinguished 

 by not having the metasternum prolonged beyond the intermediate coxae, 

 and by the fact that the femora are widened and rounded on their 

 inferior border ; there are five European species of which three are found 

 in Britain.
