I am indebted to Mr. Esben-Petersen for his kind assistance with 

 the determination of the Neuroptera and for a number of photographs, 

 of which two are reproduced on Plate II. For tlie fine photographs of 

 the wings of the two species of Gepus, special thanks are due to Mr. 

 F. W. Cauipion, who, co-operating with his brother Mr. Herbert 

 Campion, lias responded in a very successful wa}* to my desire for some- 

 thing that would show, not only the venation of the wings, but also, as 

 far as possible, their markings.

8TEN0PELMUS RUFINASUS Gtll., AN ADDITION TO THE LIST OP 

 BRITISH COLEOPTERA. 



BY OLIA'ER E. JANSOX, F.E.S, 



In July last I spent a fortnight beetle-huiiting in the Norfolk, fens, 

 most of the time being devoted to dredging in the innumerable dykes 

 that intersect the marshes adjacent to the River Bure, between Wroxham 

 and Horning, in another unsuccessful attempt to re-discover the rare 

 Bar/ous hinoduhis. I found all water-frequenting Coleoptera to be 

 unusually scarce, but on July 2-ith, the last day of my visit, my efforts 

 were rewarded by Hnding in the net a small weevil, quite uidinown to me 

 and with the affinity of which I was much puzzled. On showing this 

 to Mr. Champion upon my return, he, with his special knowledge of the 

 European and American Curculioiiidae, was able to identify it at once 

 as Stenopelmus rujinasus. This species Avas originally described by 

 Cxyllenhal (Schonh. Gen. et Sp. Cure, iii, 1836, p. 469) from North 

 America, and subsequently by Bedel (Bull. See. Ent. France, 1901, 

 p. 358), under the name of Decforsia chamjjenoisi, from specimens taken 

 in the Depts. of Eure and Charente-Inferieure in France, where it was 

 found associated with a small aquatic plant of the genus Azolla, that is 

 stated to have been introduced from North America and now become 

 naturalized in France. 



There is some diversity of opinion as to the position to which 

 Stenopelmus should be assigned in the classification of the Gurculionidae, 

 Leconte included it in the " Erirhini," as the type of a special group he
