NATURAL LOCALITIES OI- BRITISH COLEOPTERA. 179 



very many good Carahidce, which may be found under refuse on 

 the edges of ponds or in damp phices; the Lincohishire fens near 

 Boston have produced Badister iteltatiis in quantities ; the rare 

 Pterostichus aterrimus and P. anthracinus are ahuost peculiar to 

 the fens, and with P. gracilis and P. minor may be taken on 

 Wliittlesea Mere. Blethisa mult'i punctata and Oodes lielopiodes 

 are very seldom captured out of the fen districts; they have, 

 however, been found at Askham Bog, near York. There are also 

 other good insects which frequent the fens, but which are also 

 found in other localities, and cannot therefore be called true 

 fen insects, such as Dyschirius ceneiis, Ancliomenus ohlongus, 

 ElapJirus idiginosus, Amara consularis (recorded by Mr. Dawson 

 as abundant in Holme Fen, Huntingdonshire), Panagceus crux- 

 minor, Stenolophus Teutonus, Skrimsliiranus, vespertinus, and 

 dorsalis, Bradycellus placidus, Bemhidium assimile, and others. 

 Several specimens of the very rare ChlcBuius holosericeus are said 

 to have been taken near Whittlesea Mere in 1826, but I do not 

 know whether the locality has since yielded a specimen.* We 

 must not forget to mention Trechus rividaris, Gyll. {incilis, Daws.), 

 which is so great a desideratum with all collectors. Mr. Dawson 

 took two specimens at Whittlesea, and a labouring man found 

 sixteen in the fens between Holme and Yaxley ; it may therefore 

 again turn up, but is verj' probably extinct in the latter locality, 

 as almost the whole of the ground on which it was found was 

 brought under cultivation about five-and-twenty years ago 

 according to Mr. Dawson's notice of its capture. 



We might suppose that the Curculionidse would not be so well 

 represented, but, as we might expect, several species of Bagous, 

 Grypidius equiseti and others occur ; there would probably be 

 many species of Phytohius also ; Lixus parapilecticus, which now 

 appears to be becoming extinct, used to be found in some 

 numbers. 



I had intended to say a few words on salt-marshes and 

 salterns, but I must defer them to the next paper. 



* It occurred in Burwell Feu aud the ueighbourhood in 18."J2, where Dr. I'ower 

 took eight or teu specimens. — J. A. 1'.
