12 CLAVICORNIA. [Clambus. 



C. pubescens, Redt. Short oval, not quite as convex as the 

 following species, thickly clothed with very short and fine pale silky 

 pubescence, of a lighter or darker pitchy colour, with the sides of the 

 thorax lighter, apparently impunctate ; antennse yellow ; thorax as broad 

 as elytra, and broader than head (which is large), very transverse, posterior 

 angles rounded ; elytra three times as long as thorax, narrowed towards 

 apex ; under- side thickly and very finely pubescent ; legs pale yellow, 

 last segment of abdomen with a raised fold. L. | | mm. 



In vegetable refuse, hot-beds &c. ; not uncommon and probably very widely 

 distributed in many parts of England; Chatham, Darenth Wood, &c. ; Hastings and 

 other localities in the South; Knowle, Smallheath, Edgbaston, Repton, &c. ; 

 Manchester district ; Northumberland district, rare ; Scotland, not common, Solway 

 district. 



This and other species of Olambus are probably very often overlooked, 

 as they have the power of rolling themselves up into a ball, and so lying 

 quiet until danger is passed ; in walking they hold their large heads 

 stretched out horizontally, which gives them a peculiar appearance. 



C. armadillo, De. G. Very closely allied to the preceding, but of 

 darker, usually black, colour, and clothed with much more sparing and 

 longer pubescence ; the margins of thorax are brownish-red, and the legs 

 and antennae are reddish ; in this and in the other species the disc of 

 elytra is sometimes lighter ; the last segment of the abdomen is more 

 thickly pubescent, but has no fold. L. f-f mm. 



In moss, dead leaves, vegetable refuse, hot-beds, &c. ; commoner than the preceding 

 in some localities, and less common in others ; London district, generally distributed ; 

 Hastings; Devon; Soham, Cambridge; Midland districts, Bewdley, Sutton Park, 

 Salford Priors, Eepton, Ac. ; Manchester district ; Northumberland district, common ; 

 Scotland, not common, Solway, Tweed, and Forth districts; Ireland, near Dublin and 

 Belfast. 



C. minutus, Sturm. On an average distinctly larger than the two 

 preceding, and distinguished by its very smooth, shining, and glabrous 

 surface ; the sides of the thorax are rather distinctly yellowish or 

 yellowish-red, and the disc of the elytra is often lighter ; the last segment 

 of the abdomen is furnished with a little brush of hairs, and in the male 

 has also a small fovea. L. f-1 mm. 



In vegetable refuse, flood rubbish, &c. , rare, but perhaps overlooked or confounded 

 with the preceding ; Dulwich ; Cobham Park ; Horning Fen ; Southampton ; Exeter ; 

 Tewkesbury ; Bewdley ; Yardley ; Manchester district ; Northumberland district ; 

 Scotland, not common, Solway district. 



A fourth species, C. punciulum, has been included in the British list, 

 but has been dropped, as the specimens on which it was introduced 

 appear to be only small C. minutus ; G. punctulum is smaller and rounder 

 than C. minutus, and has the last joint of the antenna? only as long as 

 broad, and the last segment of the abdomen bare ; in C. minutus the 

 autennre have the last joint much longer than broad, and the last
