logy^*^^ a reference being given to every Genus already illu- 

 strated^ and may be easily continued by those who are desirous 

 of completing it. 



5thly. It will be a Catalogue of the Author's Cabinet^ those 

 without a * being his desiderata^ and of those with a J he has 

 only foreign specimens. The names in itahcs denote insects 

 which are doubtful natives. 



Those who use this Guide for labelling their Cabinets are 

 recommended to place every name in their drawers^ which will 

 eventually save a vast portion of time ; and on no account to 

 cut off the numbers^ as they will be found invaluable for refer- 

 ence and in correspondence. 



It would occupy too much space to give a complete list of the 

 Authors quoted^ but it will be necessary to state^ that wherever 

 any figures follow the generic names^ they will refer to the 

 "British Entomology'^; as Cicindela 1. refers to the first foho 

 of that work^ and it is gratifying to observe that there is scarcely 

 a page or even a column in which a reference to that Work will 

 not be met with^ showing the great extent to which the Genera 

 have been already illustrated. 



It is now upwards of eight years since the above Preface to 

 the first edition of this Guide was printed ; at that time it was 

 by far the most extensive Catalogue that had ever been published^ 

 and the numerous additions that have been made to our Bri- 

 tish Collections since that period have with great care and con- 

 siderable labour been embodied in the present edition^ making 

 it by far the most complete Catalogue of the present dayf. 



« " British Entomology, or Illustrations and Descriptions of the Genera 

 of Insects, by John Curtis, F.L.S." This work now contains 658 coloured 

 plates with representations of 7^7 Insects, besides dissections to establish each 

 Genus, aad also 650 figures of indigenous Plants from wild specimens. 



t It is calculated to comprise upwards of 1500 generic and nearly 15,000 

 specific names.
