178 THE ENTOMOLOGIST. 



sliake the bundles over it as they unload them, he will reap a rich 

 harvest, — Odacantha melanura in abundance, Dromius longiceps 

 and Sigma, and Aetophoriis imverialis being some of the best 

 species ; these of course may all be found in their respective 

 homes, but this is a very good way of obtaining them. The 

 bundles must not be fresh cut, but must have lain some little 

 time. 



The smaller beetles that may be obtained in this way are 

 legion. Atomar'ue for instance, such as A. gutta, may be found 

 by thousands ; many Atomarice seem to be fond of marshy places ; 

 thus A. Barani was found some time ago in a marshy place near 

 Eltham, and I have swept A. basalis in numbers on low swampy 

 ground near Repton. 



Very good Trichopterygidse occur in the fens, and very pro- 

 bably new ones would reward any collector who paid attention to 

 them ; at any rate exceedingly scarce species like 2\ Kii'hyi and 

 T. Championis, Ptilium ccesiimi and affine might be found in some 

 numbers. 



The Steni of the fens are very good. S. palustris may be 

 obtained in large quantities by sweeping at Wicken Fen, and S. 

 opticus at Horning Fen. S. vafellus and S. fiiscipes also occur 

 plentifully, and S. argus sparingly ; S. lustrator, S. prodltor, and 

 others may also . be found ; other good Staphylinidae, such as 

 Thinobius brevipennis, Latlirobium rufipenne and angustatum, 

 Platystetlms nodifrons, Micropeplus tesserula, &c.,may be obtained, 

 and the pretty little Hypocyptus discoidens may be taken in thou- 

 sands by shaking refuse and rushes as above described. 

 Euplectus ambiguus may be captured by sweeping rushes on a hot 

 day. Chrysomela graminis is extremely abundant at times, and 

 occasionally Phyllobrotica quadrimaculata, and the very rare 

 Adinionia a:landica, Boh. {villa, W. C.) may be found in numbers. 

 Silis riificollis is a fen insect well worth looking out for with 

 these. Malachius ruficollis sometimes occurs plentifully, and 

 Chrysomela goettingcnsis sparingl3^ Hcenionia Cvrtisi is also to be 

 found. 



Certain good Longicorns seem peculiar to the fens and fenny 

 districts, as Oberea oculata and Sapenla carcharias : the latter 

 occurs near Lincoln. Agapanthia lineatocollis may be found not 

 uncommonly on thistles. 



Besides tlie Dromii, &.C., above mentioned, the fens contain
