iv PREFACE. 



rapidly, especially in the first two classes, the Mammals and 

 Birds, that it was found necessary to conclude at the Insects, 

 and even then to give but an exceedingly short and meagre 

 account of them. This was much regretted, as my experience 

 had lain so much in the practical entomological part of Nat- 

 ural History, that during the earlier stages of the work I looked 

 forward with some pleasure to giving a very much fuller ac- 

 count of the British Insects than will be found in the last few 

 pages of this volume. 



In arrangement, the order of the Catalogue of the British

 later drawings, such as the Thorny Woodcock-shell, the Leaf 

 Insect, the Rove Beetle, together with parts of a few others,

 more, they have been extracted from works which, either 

 from their scarcity, their cost, or their nature, would be very 

 unlikely to be placed in the hanSs of general readers. 



I dismiss these pages with almost a feeling of regret, that a
