A WORKING LIST OF BRITISH BUTTERFLIES. 



It is from no desire to complicate the tangle of nomen- 

 clature or to revive controversy that I have compiled the 

 following catalogue of British butterflies. It is rather with a 

 view to provide the 'Entomologist' with an up-to-date list and 

 to secure some uniformity of nomenclature in its pages ; and 

 further, to avoid unnecessary duplication and reduplication 

 of index references. Contributors, therefore, are earnestly 

 requested, so far as possible, in their papers and notes to adopt 

 the generic and specific names hereunder set forth, since the old 

 method of lumping numerous genera under one generic name, 

 largely adopted by Staudinger and Rebel in the ' Catalog ' of 

 1901, in the light of all later (and much earlier) research work 

 is indefensible, and often absurd. British lepidopterists long 

 ago recognised, e.g. that the Blues can no longer be included 

 under the simple generic Lycxena any more than that the 

 majority of the Hesperiids are amenable to the same " omnibus " 

 treatment. The lateMr.Tutt, in his monumental, and unfortunately 

 untinished work, clearly demonstrated the scientific necessity 

 for complete revision of generic names, though, in my opinion, 

 he adopted certain specific names for which there is no his- 

 torical warrant. My purpose here, however, is merely to provide 

 authors with a working list, takmg advantage of such discoveries 

 as seem to indicate a necessary departure from the obsolete 

 generic nomenclature of the earlier systeraatists.
