" Other names might easily have been added to this list, 

 but it was thought that eleven would constitute a more 

 manageable committee than a larger number would, and 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.

Question 7 was : " By what process is the type of a 

 hetero-typical genus to be ascertained ? " and a special 

 question under this heading was : " c. What is the type of 

 Tmea, L. ? " 



On Sir George Hampson 's suggestion that " the first species, 

 or the first species agreeing with the description, to be con- 

 sidered the type," the opinions were : — 



For : 1, Hampson ; 2, Staudinger. 



Against: 1, Aurivillius; 2, Fernald; 3, Grote; 4, Kirby;

 5, Smith; 6, Aurivillius; 7, Grote (8, Scudder and 9, Stau- 

 dinger assumed to concur). 



While Sir George Ham|)son was unable to say which was 

 the first species that agreed with the description, after having 

 wrongly cited as the type gelatella, L. (a species which did 

 not occur in the 10th edition of Linne). 



Sir George Hampson has rightly accepted as the type of 

 Sphinx the seventh species ligustri, which Linne states in the 

 Fauna Gnecica was " Vulgo Sphinx,'' and also as the type

 Linne. 



It is therefore evident that the first species included in a
