I SHOULD very much regret having been under the necessity 

 of dissecting a small species, which differs so materially from 

 the type, if Mr. Westwood had not described and figured the 

 trophi, &c., of C depressus and other species in the 5th vol. of 

 the Zoological Journal: I shall, however, briefly give the cha- 

 racters of the type. 



Antennae with the 2nd joint the smallest. Mandibles with 

 3 strong teeth ; labium bilobed ; terminal joint of palpi broad 

 and truncated. Head subtrigonate, narrowed at the base and 

 broader than the thorax, which is transverse with the sides a 

 little denticulated not marginate ; tarsi 5-jointed, anterior di- 

 lated, the basal joint very minute, the posterior pair only 4- 

 jointed in the male ? with the 2nd joint as long as the 4th. 



The following species have been recorded as British: 



1. C. dermestoides Fab. — Panz. 3. 13. — depressus Herb. 

 The tarsi are similar to C. depressus F., and the 6th and 8th 



joints of the antennae are smaller than the preceding and 

 following. 



Taken by the Rev. G. T. Rudd, " who found them the 

 beginning of June running in the hot sunshine over the 

 newly barked trunks of oak trees near Lyndhurst in the New 

 Forest; they entered the cracks in the timber, which their ex- 

 tremely depressed form peculiarly adapts them for." Mr. 

 Dale also captured it at the same time. 



5. C. piceus Oliv. 4. No. 74. bis, pi. \.f. 5. — Zool. Journal, 

 pi. 47./ 1. 



6. C. Spartii Curt. Brit. Ent. pi. 510.— ater Step. 



The C. ater of Olivier is entirely of a deep black with a 

 thick head, represented also very broad in the figure, and an 

 almost heart-shaped thorax. 



Taken in abundance by Mr. Rudd out of decayed Broom- 

 stems at Coomb- wood in April and May. 



3. complanatus Wilk. — monilicornis Step. ? 



Is considerably like C. Spartii, but it is testaceous; the head 

 is broader and the thorax more narrowed behind. Found in 

 Dec. in Granaries and Cornbins in Norfolk by Mr. S.Wilkin. 



7. ferrugineus Meg.? — testaceus Ste.pl. 21./ 6. 



Found in a Granary by Mr. Babington in abundance, also 

 in an old decayed Elm in Wiltshire in Dec. by Mr. Ingpen. 



2. testaceus Fab. Under the bark of dead trees. 



4. minutus? Oliv. pi. 1./. 9. Found by the late Mr. Griffin 



amongst Indian wheat. 



8. unifasciatus Lat. Hist. Nat. 11. 256. 7.— Zool. Journal, 

 pi. 47./ 2. 



Taken in June in the New Forest by Mr. Rudd, to whom 

 I am indebted for specimens as well as of the species figured : 

 it was also found " under the bark of a Horn-beam tree in 

 Hainault Forest by Mr. Bydder." 

 The VlawUs Hypericumperforatum ( Perforated St. John's Wort).
