published in 1766-7 and 9. If these names were still rejected, comparatively 

 few alterations would be made. Doubleday's list having had almost universal 

 acceptance in this country, we have not hitherto felt the difficulties of nomen- 

 clature much. Now that the more scientific of the two leading magazines 

 adopts one nomenclature, and the other another, we are worse than any 

 one, for the capture of the same species would, in numberless cases, be an- 

 nounced under different names in these two journals, and only experts 

 would know what was meant. 



It is hoped, the following list will serve as a key to the mystery. The 

 authorities quoted are, for ■ Butterflies only, Kirov' s Synonymic Catalogue of 

 Rhopalocera ; and generally, Doubleday's Synonymic List (2nd edition) and the 

 supplement to it ; Staudinger's " Catalog der Lepidopteren des Europseischen 

 Faunengebiets," edition 1871 ; " Catalogue methodique des Lepidopteres 

 d'Europe," by M. Berce, 1861. The names of Stainton's Manual are also 

 occasionally quoted. In the very few cases where Mr. South has not used 

 the German nomenclature of Staudinger, his name is also added. There can 

 thus be seen at one glance what names are used in each country. 



The arrangement adopted is mainly that of Dr. Boisduval and M. Guenee, 

 which seems more natural than that of Doubleday ; and is certainly superior 

 to the German method, where sometimes a dozen or more incongruous genera 

 are mixed in one heterogeneous mass.
