Coriii:aria.'\ clavicorxia, 289 



pubescence pale, distinct; somebiiaes tlio whole upper surface is pitchy 

 or testaceous ; head and thorax rather strongl}'^ and diffusely punctured, 

 interspaces alutaceous ; antennae testaceous, club with joints elongate; 

 thorax rather short, subcordiforni, sometimes appearing almost orbicular, 

 with sides strongly crenulated ; elytra ahvays wider than thorax, 

 ample, with closely packed irregular rows of punctures and no marked 

 interstices ; legs testaceous or reddish testaceous. L. 2|-3 mm. 



Male with the first joint of the anterior tarsi dilated, oblong, provided 

 on each side with long and fine setose hairs. 



In haystack and flood refuse, decaying sea-weed, moss, &c. ; not uncommon and 

 generally distributed throughout England; Scotland, Forth district, comuioii 

 amongst hay and straw, and probably widely spread in other localities ; Ireland, 

 Waterford and Dublin, and probably commou. 



C. crenulata, Gyll. Nigro-piceous, or brownish-testaceous, with 

 the shoulders more or less broadly lighter in the darker specimens ; 

 pubescence yellowish ; in sculpture this species much resembles the pre- 

 ceding, but is very easily distinguished by its more orbicular thorax and 

 by having the elytra and thorax of about equal or nearly equal breadtli, 

 so that the general form is more parallel, and also by the shape of the 

 club of the antennae, which has the first two joints about as long as 

 broad ; it is also a smaller species. L. 2-2| mm. 



Male with the femora thickened, the anterior and intermediate tibioj 

 somewhat produced internally towards apex, and externally obliquely 

 truncate, and the first joint of the anterior tarsi dilated. 



In decaying sea- weed, haystack refuse, moss, &c. ; generally distributed throughout 

 England, but commoner on the coast than inland, and rarer further north ; Scotland, 

 local, maritime, Tweed, Forth, and Dee districts ; its distribution is probably the 

 same in Ireland. 



C. denticulata, Gyll. In colour, size, and form, this species 

 almost exactly resembles the preceding ; the thorax, however, is rather 

 more narrowed behind, and the crenulations at the sides are less distinct ; 

 the elytra have the shoulders more gently rounded and the apex more 

 obtusely rounded ; the abdomen has the fifth ventral segment not 

 deeply foveate ; the chief distinguishing character, however, lies in the 

 sculpture of the elytra, which are furnished with regular deeply punc- 

 tured strias, divided by narrow but distinct interstices, some of which 

 are feebly carinate towards base ; they are also furnished with distinct 

 rows of minute punctures ; the male differences are much the same as 

 in C. crenulata, except that the anterior and intermediate tibiai are more 

 angularly produced internally. L. 2-2j mm. 



In decaying sea-weed, moss, vegetable refuse, &c. ; local ; London district, common ; 

 Deal; Hastings; Horning Fen ; Cambridge; Wicken Fen; Dorchester; Birmingham 

 district ; Repton ; Sherwood ; Liverpool ; Manchester; Northumberland and Durham 

 district ; Scotland, scarce, Solway, Tweed, and Forth districts. 



C. serrata, Payk. {laiirolUs, Mannh.). Smaller than any of tlie
