jast without the fen, I took two interesting species, Scymnus minimus, Eossi, 

 and Throscus ohtiisus, Curt., in profusion. By sifting the sedge-stacks, the 

 visual fen beetles were seen, but by no means in their wonted numbers, Parnus 

 awjlicanus, Edwards, and Galerucella pusilla, Weise, being the most interesting 

 among them. In the water-net, the great abundance of Hahplus variegatus, 

 Sturm, was a noticeable feature, with its congeners, confinis, Steph., and 

 obliquus, Er., in lesser numbers. Hydaticiis transversalis, Bergst. (9 or 10), 

 Rhantus grapii, Gyll., Ihjhius obscurus, Marsh., Hydropliilus, and other typical 

 fen water-beetles rejoiced the eye, and materially increased my collection, but 

 must not tempt me to enlarge thereon ! — Hereward G. Dollman, Hove House,

A note on Ceuthorrhynchus rapse, Gyll. — Owing to its having been formerly 

 taken in the Tottenham Marshes by the Messrs. Waterhouse, as recorded by 

 Fowler, I had been on the look-oiit for this weevil on the marshes here for many 

 years, but entirely without result up to the present year. On the 5tli May last, 

 however, I had the good fortune to find an individiial of Ceuthorrhynchus rapse 

 sitting in the sun on one of the upper shoots of a tall plant of the garlic 

 mustard {Alliaria officinalis) growing at the side of a marsh ditch. A prolonged 

 investigation of all the cruciferous plants in the vicinity failed, however, to 

 produce any more, either then or since. 



Curiously enough, however, the species has recently turned up in another 

 and somewhat \inexpected locality, Mr. W. West having shown me an undoiibted 

 example of C. ra^jse, which he is positive he capttired by sweeping in Headley 

 Lane, Siu-rey, on August 6th, 1910. 



Ceuthorrhynchus rapse appears to have been first taken in this country by 

 the late Mr. Samuel Stevens, who included it under the name " Nedyus syritis " 

 (= Ceuthorrhynchtis syrites, Germ.) in a list of beetles taken by him near 

 Hammersmith, which he contributed to the first volume of Newman's 

 "Entomologist" (1842). The insect was also wrongly referred to the 

 G. inaffectatus of Schonherr* before its real identity was finally settled. In the 

 " sixties " and " seventies " the metropolitan collectors of that period were in 

 the habit of taking it in various parts of the London district, but although 

 Dr. Power on one occasion took 19 specimens, I do not gather that it was ever 

 really a common species. As far as I can ascertain there has been no record of 

 its captui-e now for a considerable niimber of years, so that its re-occurrence is 

 a matter of some little interest. 



Whether C. rapse survives in the only other British locality given for it by 

 Fowler outside the London district, namely, Portsmouth, where it is recorded 

 as having been taken by the late Mr. Moncreaif , would seem to be very doubtful, 

 as Mr. Pool informed me some time ago that most of Mr. Moncreaff's collecting 

 groimds had long since been destroyed. Mr. West, who, as is well-known, 



*This appears to have been either a complete myth or a " iiomen mulum." The name, however, is 

 included in G. R. Waterhouse's British Catalogue of 1S58, and his Pocket Catalogue of 18(51, 

 but in such a way as to .show that he was doubtful about it. There is a C. hmffictahis of 

 Gyllenhal in the European List of 190(5, but from its position it would apparently be not at all 

 closely related to the C. rapw of the same author. — F. \i. J.
