TO 
LHS SEV EN TH LDITION, 
Tus work is now published at one sixth of the price of 
the Sixth Edition, so as to bring it within reach of all 
desirous of becoming acquainted with the Natural History 
of Insects, and thus carrying out more effectually the object 
of the Authors — that of introducing others to a branch of 
science which they had found so delightful. 
Though compressed by a smaller type into One Volume, it 
contains every line of the Sixth Edition, which includes much 
new matter not in the five preceding editions; and, to ren- 
der the work more complete, the account of its origin and 
progress, furnished by Mr. Spence to the “ Life” of Mr. 
Kirsy by Mr. Freeman, is, with his permission, given 
as an Appendix.
