The design of the following pages is to 

 supply instructions, in a detached form, for 

 collecting and preserving British Insects, 

 Crustacea and Shells ; not only for the 

 Student, but also to distribute to persons re- 

 siding in the Country, who wish to oblige 

 their Entomological friends by collecting, or 

 employing others to collect for them. The 

 want of such a work, for distribution, has been 

 long felt, and it is hoped that the present will 

 be found useful for the purpose. It has been 

 the chief aim of the author to make the in- 

 structions as full and as simple as possible, 

 and many useful hints and directions will be 

 found peculiar to this work. 



To those who wish for information as to the 

 locaHties, habitats, and periods of appear- 

 ance, of particular British Insects, &c., the 

 valuable calendar in *' Samouclle's Entomolo-
