Mr. Talbot also read the following notes on the Affinities 

 and Distribution of the new Forms : — Papilio othello, first 

 obtained by Doherty, is a race of aegeus, a species distributed 

 over the whole of New Guinea and its satellite islands, the 

 Bismarck Islands, and from Queensland to Victoria. The $ is 

 sometimes polymorphic. To the two forms already known of 

 Othello we now add a third. This form represents a type of 

 aegeus ? already known from the neighbouring island of Mefor 

 and from New Guinea. 



The c? exhibited is remarkable for the yellowish tint on the 

 hind-wing. This occurs to a much less extent in two other 

 specimens. A well-marked case of this phenomenon in the 

 race, or menus, was made the subject of a separate species by 

 Grose-Smith. Dr. Jordan points out in " Seitz " that a speci- 

 men of P. amhrax possessing a similarly coloured band, was 

 received in the same collection as Grose-Smith's " pandoxus." 

 We have received a number of P. othello and its three forms of 

 9 ; previous to this only one o and two ? $ were known. 



P. euchenor is a typically Papuan species, also occurring in 

 the Bismarck Archipelago. The race now described from Biak 

 shows more relationship to depilis from the Bismarck Islands. 



P.felixi is a distinct species belonging to the Macareus-gTou.Y> 

 of Papilios. It is more nearly related to leucadion from 

 the Moluccas than to the New Guinea forms of this group. 



Pieridae. 



The collection made by Doherty contained one Delias, 

 which was described by Grose-Smith as euphemia. We now add 

 six others. Half of these have affinity with I\Ioluccan forms, 

 and half with New Guinea forms. The Delias euphemia, of 

 which we received a long series, is transitional from the New 

 Guinea mysis to bagoe of the Bismarck Islands. This number 

 of distinct Delias inhabiting Biak is another illustration of 

 what has been observed in New Guinea, viz. the plasticity of 

 members of this genus, leading to the production of distinct 

 forms in nearly every small and isolated area.
