Mr. Rye in company with C. marginatus at Dover ; Mr. Rye was strongly of opinion 

 that they are nothing bat a variety of C. marginatus (v. Eut. Monthly Mag. VI. 

 229). 



C. quercicola, Payk. (versicolor, Bris. ; uniguttatnt, Marsh.). A 

 small and rather conspicuous species ; black, upper sxirface depressed, 

 underside thickly clothed with whitish scales, upper surface with 

 variegated grey and dark scales, the latter sometimes having a slight 

 violet reflection ; at the base of the suture of the elytra there is a con- 

 spicuous oblong white patch, situated on the two sutural interstices ; 

 thorax not strongly constricted before apex, with the disc depressed, 

 plainly channelled at base, closely punctured, with lateral tubercles, 

 basal margin almost straight ; elytra with rather fine punctured striae, 

 interstices moderately broad, apex slightly muricate, legs black. L. 

 If -2 mm. 



By sweeping herbage; occasionally found in moss; locally rather common, but 

 apparently never abundant ; Mickleharn, Darenth, Haslemere, Cobham, Belvedere, 

 Chatham,* Faversham, Cowley, Crohamhurst, Bearsted ; Brighton ; Exeter (on horse 

 ladUh, very rare (Parfitt)); Foremark, near Repton ; Old Trafford, Manchester, 

 rare ; Northumberland and Durham district, rare, Heaton and Little Beuton ; Holy 

 Island; Scotland, rare, Forth district ; Balumto, Fifeshire (Power). 



The var. Crotchi (C. Crotchi, Bris.) differs from the type form by 

 its more depressed thorax, of which the anterior margin is less reflexed, 

 and by its testaceous tarsi, of which the claws are smaller. I do not 

 know of any localities for this variety, which was described by M. Ch. 

 Brisout from England only. 



C. mixtus, Muls. (nigroterminaft'.s, "Woll.). Short and broad, 

 black, scantily covered on the upper surface with white scales, which 

 are thicker on an obscure patch at scutellum ; the hinder margin also 

 of the elytra is more or less densely clothed with white scales ; occa- 

 sionally the scutellary patch is very obsolete or absent ; thorax without, 

 or with very obsolete, lateral tubercles, anterior margin raised ; elytra 

 short, subquadrate and narrowed behind, interstices rugose ; antennae 

 dark ; legs black, tarsi yellow red, last joint black at apex, femora 

 toothed ; the species may be known by its short form and abbreviated 

 elytra ; C. mixfits is characterized by M. Bedel as having no special 

 raised tubercle at sides, and no spot at scutellum, and he allows 

 that the identity of this species with Wollaston's nigro-terminatus 

 needs confirmation ; they appear, however, to belong to one species. 

 L. 2-2 mm. 



Very rare ; Gainsborough (one specimen, Crotch) ; one specimen in Dr. Power's 

 collection, without locality, labelled " mirtus, Muls."; the species seems to require 

 some further confirmation as British. 



C. troglodytes, F. (spiniger, Herbst.). Lighter or darker reddish 

 brown, rather shining, moderately convex, underside comparatively 

 scantily clothed with greyish scales, thorax with three more or less
