192 A CATALOGUE OF THE LEPIDOPTERA OF 



proper time for a few general remarks on the distribution, &c., 

 of tlie species found within the two counties, and accordingly 

 I shall defer them till that time arrives, noticing, however, 

 any peculiarity of habit, &c., of any particular sj^ecies as it 

 comes before me. 



It only remains to be stated that the arrangement I have 

 adopted is that of my lamented friend, the late J. F. Stephens, 

 Esq., as given in the Catalogue of British Lepidoptera, edited 

 by him for, and published by, the Trustees of the British Mu- 

 seum, not because it is in entire accordance with the views of 

 many of our own Lepidopterists, or those of continental Europe, 

 but as bearing something like the stamp of authority as regards 

 British Lepidoptera, and quite sufficient for my purpose. Pos- 

 sessing an almost complete library on European Entomology, I 

 might have inserted references to a great number of authors and 

 their works ; I have, however, confined myself to such as apj)eared 

 necessary to identify the species, or mark the limits of its varia- 

 tion, giving the preference to those most readily accessible.
