Question 25.— (G. T. Bethune-Baker.) 



Are we to substitute " idas L." in lieu of '• argynxjnomoii 

 Bergst." ? 



Opinion 25. — Linne described Papilio idas [Syst. Nat. (ed. 

 10)1.488 sp. 192 (1758)] with ''Habitat in Indiis." This 

 must be regarded as a doubtful species, and § Idas Linn6 [Fn. 

 Suec. (ed. 2) 284 sp. 1075 (1761)] is invalid as a homonym — 

 argyronomon Brgstr. [Nomencl. Ins. 2. 76 Pf. 46*1-2 (1779)] 

 cannot be affected by idas L. [Syst. Nat. (ed. 10, 1758)] until 

 this species ex " Indiis " has been identified with absolute 

 certainty.

Question 26.— (G. T. Bethune-Baker.) 



Are we to substitute " ramhnri Vty." in lieu of " idas 

 Ramb." ? 



Opinion 26. — Folynmmatus idas Rambur [Fn. Ent. Andal. 

 2. 266-8 Pf. 10*5-7 [1840] is a homonym, a new name is 

 therefore required for this species — ramburi Vty. [Jr. Linn. 

 Soc. Lond. Zool. 32. 189, 191 (1913)] should be accepted if valid.
