3 THE ENTOMOLOGIST. 



has yielded seven or eight species, all of which are at the present 

 day Trans-Pyrenean, enabling us to correlate the Lexden peat 

 with a marine deposit near Chichester, in which about a dozen of 

 the shells are Lusitanian. 



In the following lists 1 have quoted all the forms that have 

 come under my notice, either by reading or personal research. It 

 is probably incomplete, and I hope other and more experienced 

 entomologists will fill up the gaps. For convenience I have 

 placed them alphabetically.

ENTOMOLOGY OF DELAMERE FOREST. 

 By J. Arkle. 



From the Northgate, Chester, to Delamere, is ten miles by 

 rail. In a few minutes we find ourselves at Delamere Station, 

 from which the forest stretches to right and left, with a length
