282 STAPHTLINID^. [CaJlUS- 



behind, where it is evidently less broad than elytra, with one or two 

 large punctures near anterior margin, a large circular impression on disc, 

 and one or two smaller ones behind, which are often wanting ; elytra 

 rather thickly and coarsely punctured, about as long as thorax ; hind 

 body long, finely and thickly punctured ; legs black or brownish Avith 

 the tibiae and tarsi more or less ferruginous, anterior tarsi more or less 

 dilated in both sexes. L. 10-13 mm. 



Male with the seventh ventral segment of hind body rather strongly 

 sinuate at apex, sixth segment feebly sinuate. 



On the sea-coast, under stones and sea-weed ; very local ; Southsea and Ports- 

 mouth (H. MoncreafF, J. J. Walker, &c ) ; Shoreham ; Worthing (E. Saunders); 

 it occurs more plentifully between Juue and October ; according to Mulsaut aud Rey 

 it sometimes digs a burrow for itself in the damp mud. 



C. fucicola, Curtis. Elongate, linear, somewhat parallel-sided, 

 pitchy black ; head large, variable in size, but at least as broad as, and 

 usually broader than, thorax, subquadrate, with large coarse punctures, 

 especially behind eyes ; antennae dark, with the insertion of the first 

 joints, aud the last joint (as a rule), ferruginous, penultimate joints 

 slightly transverse ; thorax longer than broad, distinctly narrowed 

 behind, where it is narrower than elytra, with two series of three large 

 punctures on disc ; elytra a little longer than thorax, finely and thickly 

 punctured ; hind body distinctly, and rather thickly, punctured ; legs 

 ferruginous, with the apex of femora and tibiae sometimes darker ; 

 anterior tarsi moderately dilated in male, less dilated in female. L. 9- 

 10 mm. 



Male with the seventh ventral segment of hind body rather deeply 

 and triangularly emarginate at apex, sixth segment more broadly and 

 less deeply emarginate. 



Oa the sea-coast, in decaying sea-weed ; very local ; London district, rare, Sheerness ; 

 Littk'hampton ; Isle of Wight, Ventnor, &c., not uncommon in early spring ; Rotting- 

 dcan, Brighton ; Portland ; Falmouth ; Devonshire ; Wales ; Douglas, Isle of Man ; 

 Northumberland district, Marsden, rare ; Scotland, Forth district, Dalmeny ; 

 Murray's locality has lately been confirmed by Mr. Logan of Colinton (Ent. Monthly 

 Mag., xxiii. 161) ; Ireland, Killiney, near Dublin (Power). 



C. xantlioloma^ Grav. Dull black or pitchy black, with the 

 margins of the elytra testaceous ; it much resembles the preceding 

 species, but, besides the difference of colour it may be distinguished by 

 the evidently finer punctuation of the elytra, which are plainly longer in 

 proportion to the thorax, and especially by the longitudinal lines of grey 

 pubescence on the hind body, which are formed by tufts of hairs 

 arranged on each side of the apex of each segment ; the antennae are 

 dark, and the legs are more or less pitchy, but variable in colour, being 

 sometimes almost entirely testaceous ; the sixth and seventh ventral 

 segments of male are sinuate, the latter rather strongly with a longi- 

 tudinal smooth line before sinuation. L. 6-9 mm. 



In decaying sea-weed; abundant on the coast throughout the kingdom.
