86 LÉPIDOPTÉROLOGIE COMPARÉE 



The whole subject of the nomenclature of the various forms 

 of this C œnonympha was, indeed, admirably worked out by 

 Dr. F. J. Buckell, M. B., in a paper read before the City of London 

 Entomological Society, October I5th 1895, which, for the benefit 

 of my French colleagues, I may state is not the Entomological 

 Society of London, but one of our several flourishing Metropolitan 

 Natural History Societies. This paper is also published in the 

 Entomologisfs Record (Vol. VII, pp. 100-107) and, as far as 

 Britain is concernée!, constitutes an exhaustive account of the 

 three forms of the butter fly known to our collectors. 



" Lepidopterisfs ", says Tutt {loc. cit.), " are advised to follow 

 Buckell in ail détails relating to this species. .. It is a pity that 

 more care has not been taken to digest his work before adding 

 another tangle to the already overladen synonymy. It may be 

 taken for granted that his conclusions are absolutely correct. " 

 High praise, but not undeserved; as anyone who turns to 

 Dr. Buckell's work will agrée; and hère I may say that it is a 

 matter of universal regret among British entomologists that Tutt 

 did not live to achieve finality for his splendid studies of British 

 butterflies, and i,ncidentally to give Dr. Buckell's paper a wider 

 publicity than it can ever obtain in the pages of a Society's Annual 

 Report, or a monthly Magazine. 



I do not propose to enter further upon the subject of the nomen- 

 clature of tiphon (this spelling is apparently the original, and 

 therefore that which should stand); but I venture to reproduce 

 the conclusions arrived at (omitting the excellent " life-history " 

 of each synonym) by Dr. Buckell. They are as follows : —
