ANOTHER NEW BRITISH LONGICORN {CRIOCEPHALUS 

 RUSTIC US, Dej.). 



BY D. SHARP, M.A., F.R.S., and T. GILBERT SMITH. 



VVlieii Colonel Yerbury was looking' for Callicera yerhuryi he 

 fountl a large beetle which is now in the collection at the British 

 Mnseum. On examining this insect to-day we find it to be a fine 

 female individual of Onocepknlus rusticus, Dej. 



As we are engaged on a paper as to the species of Criocephalus, 

 it is not necessary at present to do more than record the discovery. 



Colonel Yerbury may well be congratulated on finding at the 

 same time two such interesting additions to the British Fauua.

MALACRIUS BARNEVILLEI, Puton, AN ADDITION TO THE 

 BRITISH LIST. 



BY G. C. CHAMPION, F.Z.S. 



Mr. H. J. Thouless, of Norwich, has receiitly sent me for 

 determination three males and seven females of a Malacliius captured 

 by him on the sand hills at Hunstanton, Norfolk, on June 21st, IS99, 

 in <'onvolvuhts-?Lov{GY^. They are very like ilf. ^5/r^W^s at first sight, 

 and might easily be mistaken for the immaculate form of that species, 

 but are really referable to M. harnevUlei, Puton, the Norfolk speci- 

 mens agreeing precisely with the full descriptions of that insect given 

 by Mulsant (Vesiculiferes, pp. 72-76) and Peyron (Monographie des 

 Molachiides, pp. 55, 50). M. barnevillei forms the type of Mulsaut's 

 subgenus Hi/popfilus, distinguished by the narrow transverse excava- 

 tion at the apex of the elytra in the ^, and the strongly developed 

 membrane of the tarsal claw^s in both sexes. M. viridis, M. hipustu- 

 hitus, and M. ceneiis belongs to Malacliius, sensu stricto, in which the 

 elytra are unimpressed at the apex in both (^ and ? ; and our other 

 British species, M. marginellus, to the subgenus Clanoptilus, Muls., 

 which has the elytra bispinose and broadly and deeply excavate at the 

 apex in the ^ . The ? of M. barnevillei, it is true, closely resembles 

 the same sex of M. viridis, but it is easily distinguished by the flavous 

 or testaceous colour of the anterior and intermediate tarsi, and of the 

 front of the head, &c., in this respect being very similar to M. margi-
