THIS SEVENTH EDITION. 



This 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. 

 KiRBT by Mr. Feeeman, is, with his permission, given 

 as an Apnendix.
