Prothoe australis ranges over New Guinea and adjacent 

 islands. A very distinct form was received from Biak. 



Satyridae. 



Elymnias cybele is distributed from the Moluccas to the 

 Bismarck Archipelago. The Biak form is most nearly allied to 

 holofernes from the Bismarck Islands. 



In Elymnias cinereomargo we have a distinct form of viri- 

 descens which has only as yet been found at Humboldt Bay, and 

 on the Sattelberg in (late) German New Guinea. 



Melanitis amabilis ranges from the Moluccas to the Bismarck 

 Islands. We have only ?? from Biak, but these are slightly 

 different from the typical form in the Bismarck Islands. 



Heterocera. 



Asota intermedia. 



The collection contained but few moths. One is distinctly 

 new to the genus Asota of the family Hypsidae. It differs 

 from all other known forms in having a black lateral stripe 

 on the second joint of palpus. It is a sort of mixtum com- 

 positum, blending the characters of two species. 



Geographical Races of Cocytia durvillei, etc. — The 

 Honble. Walter Eothschild, F.R.S., exhibited a series of the 

 four geographical races of Cocytia durvillei, Boisd., and Euco- 

 cytia meeki, Rothsch. and Jord. He remarked that Sir George 

 Hampson considered these insects to constitute a special 

 family, Cocytiadae, which he placed between the Lymantriadae 

 and the Hypsidae. But Mr. Rothschild considered them as a 

 subfamily of the Noctuidae, which should be placed after the 

 Mominae. The following is a synopsis of the group : — 



Cocytianae. 



Cocytia durvillei f. durvillei, Boisd., New Guinea; 

 Cocytia durvillei f. veitchi, Rothsch., Bat j an and Halmaheira ; 

 Cocytia durvillei f. aurantiaca, Rothsch., Timor Laut Islands ; 

 Cocytia durvillei f. chlorosoma, Butl., with ab. ribbei, Druce, 



Aru Islands ; 

 Eucocytia meeki, Rothsch. and Jord., New Guinea.
