"British Museum (Natural History), 

 Sept. i2ih, 1896. 



Dear Sirs, 



As there is a probability of a new British Museum descrip- 

 tive Catalogue of all the described species of Heterocera being 

 shortly commenced, it is thought advisable to consult a certain 

 number of the best known authors on the Lepidoptera as to the 

 system of nomenclature which is to be adopted. With this object 

 in view, the enclosed list of questions is sent to you, and if you will 

 be good enough to express your views on the subject they will be 

 of great assistance in forming the scheme of the work, and perhaps 

 contribute to attaining a more uniform system of nomenclature in 

 the Lepidoptera. 



The names selected for consultation are : — Prof Scudder, Prof. 

 Fernald, Prof J. B. Smith, Dr Staudinger, Herr P. C. T. Snellen, 

 Prof. Aurivillius, Prof A. R. Grote, Lord Walsingham, E. Meyrick, 

 Esq., W. F. Kirby, Esq., and Sir G. F. Hampson. 



Other names might easily have been added to this list, but it 

 was thought that eleven would constitute a more manageable com- 

 mittee than a larger number would, and that those selected 

 sufficiently represented the various opinions on the subject and the 

 countries most interested in the Lepidoptera. 



It is proposed to circulate the papers once for you to give your 

 opinions and then again for you to see the answers given and make 

 any additional remarks that strike you. 



I am, dear Sirs, 



Yours faithfully, 



G. F. HAMPSON."
