ADDRESS. 



My Systematic Catalogue of British Insects having extended 

 considerably beyond the limits originally designed, I have been 

 induced to publish the subjoined abridgment thereof, in a form 

 that may be conveniently carried in the pocket for reference while 

 travelling, or for the purpose of marking off desiderata, ticketing 

 cabinets, &c. Notwithstanding its extreme compactness, it con- 

 tains the names of nearly 10,000 species, a far greater number than 

 any other individual can possibly introduce, as no indigenous col- 

 lection hitherto formed is equal in extent throughout all the orders 

 to the one which I possess, and which is arranged in conformity to 

 the following Catalogue. 



In accordance with the plan adopted in my other publications, 

 I have inserted all the described species of doubtful origin, as 

 well as those whose names have as yet appeared in MSS. only, 

 as the greater portion of the latter will ultimately appear in my 

 Illustrations; and the mere introduction of a name does not 

 necessarily imply that it must be imprinted on the memory: — the 

 former insects are distinguished by having their names in italics; 

 and the latter (as well as uncharacterized genera) by having the 

 names of their authors similarly distinguished : — to such insects as 

 I possess foreign specimens of alone, a J is attached, and a t to 

 those which are desiderata. 



%* The names of the genera between ( ) being pre-occupied 

 must be changed : — and where figures are introduced, they indicate 

 the number of species in the respective genera.
