Question 16.— (G. T. Bethune-Baker.) 



Are we to substitute '•'■ iduhe niobe L." in lieu of " niube 

 eris Meig." 1 



Opinion 16. — No. The original description of Papilio 

 niobe L. [Syst. Nat. (ed. 10) 1. 481-2 sp. 143 (1758)] 

 mentions '^maculis XIII arr/enteis," and this settles the point 

 that Dr. Verity's substitution is not justified.

Question 17.— (G. T. Bethune-Baker.) 



Are we to substitute '■'■ esperi Vty." for '■'■ adippe auctt."? 



Opinion 17.— No. The specimen now labelled '' cydippe" 

 and "adippe" in Linne's writing is niobe L. (N.B. not eris 

 Meig.), but this does not tally with Linne's description of 

 cydippe L. [Fn. Suec. (ed. 2) 281 sp. 1066 (1761); = adippe 

 L. (1767), auctt.], having one more silver spot in the marginal 

 row, and several between the central row and the basal spots, 

 in addition to the " macidis 23 argenteis " mentioned in the 

 original description. The only other specimen in the collec- 

 tion which can be Linn^an is a ,^ '^adippe"; this tallies 

 exactly with the description of cydippe, and may be that from 

 which the description was made. 



Linne described two different species under the same name 

 "Papilio cydippe," viz. : — 



1. Papilio cydippe L. Fn. Suec. (ed. 2) pp. [35], 281 sp. 1066 

 (1761). >Suec. 



2. Papilio cydippe L. Amoen. Ac. 6. 409 sp. 76 (1763); 

 Clerck Ic. Ins. 2. Pf. 36-1 (1764); L. Syst. Nat. (ed. 12) 

 1(2). 776 sp. 163 {17 (u)~"I/abitat in India." 



In 1767 Linne noticed that he had given the same name 

 to two different species, and he changed the name of the 

 European species to Pajnlio adippe L. [Syst. Nat. (ed. 12) 

 1(2). 786 sp. 212 (1767)], remarking "i?t Fauna Cydippe
