NEW BRITISH SPECIES, ETC., IN 1870. 49 



British by mere accident, as Mr. Crotch tells me that he has 

 for some time been aware of its occurring in this country, — 

 where, indeed, it would seem, from his experience, to be less 

 rare than B. hinodulus. My example of B. nodulosus, ob- 

 tained from Mr. Brewer, to whom I believe it passed from 

 the late Rev. H. Clark's collection, has been corroborated 

 for me by M. Brisout. It is of about the same size and 

 facies as hinodulus, but may readily be distinguished from 

 that species by its possessing only one nodule near the apex 

 of each elytron (on the 4th interstice) instead of two eleva- 

 tions (on the 2nd and 4th interstices). 



B. nodulosus was some time ago erroneously introduced 

 by myself into our list, on the authority of an enormous 

 abraded example of B. lutulentus. See Ent. Ann., 1864, 

 p. 86.

vicinus, Brisout. 

 M. Brisout, who has confirmed certain small pseudo-chry- 

 santhemi from Southend for me as his C. mcinus, has also 

 communicated to me the above synonymy, on the authority 

 of Germar's type. 



C. Iriangulum is itself referred as a synonym to C. mol'itor 

 (Gyll.) Schon., I. c, p. 153, in the 3rd edition of De Mar- 

 seul's Catalogue.

This insect, differing from C. marginatus solely in having 



only six (instead of seven) joints to its funiculus, has been
