292 CLAVICORNIA. [Corttfaria. 



elytra, with sides very slightly narrowed behind; elytra parallel-sided, 

 with apex rounded, with distinct punctured striae, each interstice fur- 

 nished with a row of small hairs, and a series of minute punctures ; in 

 some specimens the disc of the thorax has an impression on each side ; 

 in the male the anterior and middle tibiae are slightly bent inward at 

 apex. L. 1^-1 \ mm. 



In haystack refuse, moss, &c. ; often by sweeping; generally distributed and common 

 throughout the greater part of England ; Scotland, not common, Forth and Solway 

 districts j Ireland, near Belfast and Waterford, and probably common. 



C. fenestralis, L. (rufula, Zett. ; Lafhridius ferrugineus, Marsh.). 

 Oblong, rather depressed, shining, with very short pubescence, of a 

 dark chestnut-brown colour with the head black ; thorax transverse, 

 obtusely quadrangular, only a little narrower than elytra, finely punc- 

 tured, with the sides only slightly narrowed towards base and obsoletely 

 crenulate ; elytra rather broader behind than in front, with fine punc- 

 tured striae and very minute rows of punctures on interstices j legs 

 ferruginous ; male characters as in the preceding. L. If mm. 



In vegetable refuse, moss, &c. ; occasionally by sweeping ; riot common, and scarce 

 where it occurs, often being found singly; Chatham, Sevenoaks, Darenth Wood, Wey- 

 bridge, Ashtead, Horsell, Shirley, Croydon, Caterham, Esher, Crystal Palace (in 

 corridors) ; Sohara and Wicken Fen, Cambridge ; Glanvilles Wootton ; Manchester 

 district; Scotland, rare, Solway and Dee districts; Ireland, near Dublin. 



The rather broad form (which is something like that of N. gribbosa), 

 chestnut-brown colour, delicate sculpture, and rather shining appear- 

 ance Avill serve to distinguish this very distinct species from its 

 allies. Other species besides those above described have been on 

 different occasions erroneously introduced as British, and have after- 

 wards been dropped ; considerable confusion has also been caused by 

 the descriptions of certain species described in Stephens' Illustrations 

 not answering to the insects standing under the name in his collection ; 

 the species, as observed above, are so variable in different characters 

 that it would require a very careful examination of all the series in 

 our collections, and a close comparison with the continental types before 

 the question of the British species could be considered as settled ; it is 

 probable that we possess C. linearis, and perhaps Dr. Sharp's series 

 standing under fulva should be referred to C. longicollis (a species 

 that he inserts with a ? in his last catalogue), as except for their size, 

 which should be rather smaller, they agree very well with the descrip- 

 tion of that species ; they were mostly taken by Mr. Shepherd from an 

 old carpet in his house in Fleet Street, and may perhaps be an im- 

 portation ; three or four specimens were found in old wood in Newcastle 

 Street, and one came from Mr. Crotch without locality.
