This genus contains about twenty species, of which ilve occur in 

 Europe ; the others have been described from Ceyh^n, Western Africa, 

 and North, Central, and South America (two of the hitter having been 

 found in Chili) ; our two British species are very distinct ; this is not, 

 however, the case with some of the exotic species (e.g. C. camjitodoides 

 and C. thalijcroides), Avhich, as their names imply, bear a close super- 

 ficial resemblance to otVier divisions of the NitidulidjE. 



I. Size larger; form broad oval; thorax dark, except extreme 



margins of sides ; club of antennae dark C. strigata, i?'. 



II. Size smaller ; form long oval ; thorax with margins broadly 



testaceous ; antennae entirely reddish or reddish-brown . . . C. impeeialis, F. 



C. strig-ata, F. (lateralis, Sahib.). Of rather broad oval form, 

 convex, thickly punctured, clothed with very fine pubescence, and with 

 very fine outstanding setai at the sides of elytra ; colour dark, fuscous, 

 ■with the mouth, sides of thorax, and margins of elytra reddish, and two 

 irregularly formed dentate bands on elytra yellowish or reddish-yellow ; 

 antennae brownish-red with club dark ; thorax large, fully as broad 

 at base as base of elytra, base sinuate, not margine<l ; legs red. L. 

 3-5^ mm. 



At sap and under bark of oaks, &c., very often in connection with the burrows of 

 Cossus lignix>erda ; not common ; Richmond Park, Coombe Wood, Shirley, Chuidon 

 Common (Surrey), Westerham (Kent), Belvedere, Cobham Park ; Hastings ; New 

 Forest ; Southampton ; Dean Forest ; Knowle, near Birmingham ; Colchester ; 

 Barmouth, iu fungi; Bretby Wood, near Repton, by sweeping; Dunham Park, 

 Manchester. 



C. imperlalis, F. Of more elongate form, and not so convex as the 

 preceding species, and considerably smaller ; prevailing colour reddish- 

 testaceous ; vertex of head, disc of thorax, and two or three very irregu- 

 lar bands on elytra, dark ; antennse and legs red-brown ; it also differs 

 from G. strigata in having the outstanding setse on the sides of elytra 

 much more distinct. L. 3-4 mm. 



Taken under the same circumstances as and often in company with the preceding, 

 but rarer ; Clandon Common, Coombe Wood, and Cobham Park ; Hastings ; 

 Glanvilles Wootton; New Forest; Southampton; Knowle; Dunham Park, Man-

This genus, in its widest sense, contains about thirty species, whicli 

 are very widely distributed, but chietly occur in the Northern llemi-
