 SYNOPSIS 



The names published for the genera of butterflies of the world from 1758 to the end of 1963 

 are listed alphabetically, with their type-species and requisite references. The methods em- 

 ployed and the building up of the list are elucidated. 



Introduction 



i. object of the present work 



The object of the present work is to provide as complete as possible a list of the 

 generic names published for the butterflies from the inauguration of zoological 

 nomenclature by Linnaeus in 1758 down to December 1963, with a full biblio- 

 graphical reference to the place where each name was first validly published and the 

 date of its publication. Each entry includes a statement of the name of the nominal 

 species which is the type-species of the genus concerned, with a full bibliographical 

 reference to the place and date of publication of the name of that species. Finally, 

 particulars are given of the Article in the International Code of Zoological Nomen- 

 clature under which the type-species was determined, wherever this appears 

 desirable. 



The names enumerated in the present work fall into the following classes : — 



(1) names of genera duly established with a description or other indication ; 



(2) names which are Incorrect Original Spellings of names originally published in 

 two or more spellings ; 



(3) names which are Emendations of previously published names ; 



(4) names which are Incorrect Subsequent Spellings of earlier names, i.e. variant 

 spellings of such names, other than spellings deliberately introduced as emenda- 

 tions ; 



(5) names which originally appeared in works later rejected by the Commission as 

 not being available under the Code for the purposes of zoological nomenclature 

 or in works expressly suppressed for such purposes by the Commission under its 

 Plenary Powers ; 



(6) names suppressed by the Commission under its Plenary Powers for the pur- 

 poses either of the Law of Priority or of the Law of Homonymy or for both of 

 those purposes. 



Special care has been taken to distinguish between Emendations and Incorrect 

 Subsequent Spellings in view of the great difference in the status assigned in the 

 revised Code (Article 32) to names belonging to these two categories. Emendations 

 possess status in zoological nomenclature ; Incorrect Subsequent Spellings do not. 



[Editor's Note. In the Alphabetical List of the Generic Names, classes 1 and 3 above are 

 printed in bold italic capitals ; classes 2, 4, 5 and 6 in italic capitals. Type-species of classes 1 

 and 3 are printed in bold upper and lower case, of the other classes in italics.]
