Appias alhina is a common species distributed from India 

 to the Moluccas and Philippines, according to observations 

 already recorded. We have received it from the Arfak 

 Mountains, its occurrence in New Guinea not having been 

 previously detected. The most easterly point of its range is 

 Biak, and from here we have a long series. This represents a 

 distinct race. The ? is polychromatic, and five forms occur in 

 Biak. It does not appear that any of these differ from the 

 forms already known from other parts of the species' range. 



Appias ada is the Moluccan and Papuan representative 

 of the species lyncida, which ranges from India to Celebes. 

 Appias ada is distributed over the Moluccas, New Guinea and 

 its islands, the Bismarck Islands, Solomons, Marianne and 

 Caroline Islands. We now add a race from Biak to the fifteen 

 already enumerated. 



Pareronia chinki is a very distinct form of the genus and allied 

 to jobaea. This species is represented in the S. Moluccas, Obi, 

 Waigeu, N.-W. Dutch New Guinea, and possibly on the Key 

 Islands. 



Two species of Elodina were received from Biak. One of 

 these agrees with andropia, Butl., from New Guinea. The 

 other more nearly resembles umhratica from the Solomons, but 

 is distinct, though perhaps a race of it. 



Euploeinae. 



Euploea tripunctata is a distinct form allied to lacon from 

 N. Britain, and unlike; anything from New Guinea or the 

 Moluccas. 



Euploea incerta is also distinct, though in appearance much 

 resembling obscura and cerberus from the Bismarck Islands. 

 It is more nearly allied to obscura. 



Euploea albicosta is a curious species which is difficult to 

 place, and we can find no near ally. 



Nymphalidae. 



Cynthia arsinoe ranges over the Moluccas, New Guinea and 

 its satellite islands, Queensland, and the Bismarck and 

 Solomon Islands. The Biak race seems nearer to rebeli from 

 the New Guinea mainland.
