70 CLAVicoRNiA. \_Colon. 



apex, more finely punctured tlian thorax, without traces of dorsal stria?, 

 hut appearing in certain lights somewhat transversely wrinkled ; legs 

 hrownish-red. L. 1|-2| mm. 



Male with the anterior margin of the clypeus slightly emarginate in 

 middle, and the posterior femora furnished behind middle with a small 

 tooth; 



By sweeping in the evening, and occasionally by beating ; very widely distributed 

 and sometimes not uncommon ; London district generally distributed ; Esher, Shirley, 

 Forest Hill, Caterham, Ashtead, Dorking, Sevenoaks, Darcnth, Chatham, &c.; Heme 

 ]?ay ; Wrabnes?, Essex; Glanvilks Wootton ; Knowle ; Portishead ; North Wales; 

 Ki'pton ; Northumberland district; Scotland, not rare, Solway, Tweed, Forth, 

 Moray, and Clyde districts ; Ireland, Co. Wicklow. 



This species seems to be very variable in size and colour, and many 

 mistakes have been made in consequence ; it is by far the commonest 

 species of the genus. 



C- appendiculatum, Sahib. Oblong-ovate, slightly convex, fus- 

 cous, clothed with fine silky greyish-yellow pubescence ; antennte 

 ferruginous with a rather strong club, which is darker except at apex ; 

 thorax transverse, not broader than elytra, very closely and finely 

 punctured, with the posterior angles nearly right angles ; elytra a little 

 narrowed towards apex, very thickly and finely punctured, with traces 

 of fine striaj towards base ; legs ferruginous. L. 2-3 mm. 



Male with the posterior tibiae curved, and the posterior femora 

 armed with a long spinose tooth, furnished at apex with a tuft of 

 hairs. 



By evening sweeping ; very rare ; Eeigate (Brewer) ; Birch Wood (Power) ; 

 Scotland, very rare, Solway district, banks of Nith (Sharp). 



C. calcaratum, Er. ( ? pygmceum, Er.). This species is allied to 

 the preceding, but may be distinguished by its smaller size and lighter 

 colour, and also by the fact that the elytra present no traces of dorsal 

 stria3 ; in the male the posterior margin of the thorax is not emarginate 

 near the posterior angles, whereas in the preceding species there is a 

 slight emargination ; the posterior femora of the male are armed, with a 

 long spinose tooth as in the allied species. L. 1^-2 mm. 



Very little appears to be known regarding this species as British ; it was, I believe, 

 taken by Haliday, and there is a doubtful specimen in Dr. Sharp's collection from 

 Eccles, Thornhill, near Dumfries. 



C. denticulatum, Kr. This species is closely allied to the two 

 preceding ^species, and ajipears to be intermediate between them as 

 regards size ; the colour is usually dark brown ; the distinguishing 

 character is found in the male, in Avhich sex the posterior femora are 

 furnished with a small pointed straight tooth, instead of with a long 

 spinose tooth as in the other two species. L. l|-2j mm. 



By evening sweeping ; very rare ; Hythc (Rye) ; Darenth V/ood (Power) ; Scotland, 

 Tweed district, Cheviots (Sharp).
