in the Wandammen Mountains, during Nov. 1914. These 

 mountains, which had never previously been explored ento- 

 niologically, are situated near Wandammen Bay, an inlet 

 of Geelvinck Bay on the north-east side of the island. 



The Heterocera are not yet fully worked out and may 

 yield other new forms. 



A catalogue of the wonderful collection made by Messrs. 

 Pratt on this and other expeditions in Dutch New Guinea and 

 the Schouten Islands, is in course of preparation. 

 The following species are shown : — 



Papilio (Troides) chimaera is represented by dracaena, subsp. 

 nov. Another race also inhabits Central Dutch New Guinea. 

 We received no ^ of the present form, but a specimen supposed 

 to be a male of dracaena was nearly taken by a native 

 collector, who stated that the hindwing was withovit black 

 spots. 



P. alhertisi, Ob., a rare species inhabiting North Dutch New 

 Guinea. 



Delias mariae is a distinct species, which has affinity with 

 clathrata, R. and J., from British New Guinea. 



Delias tessei is nearest to hapaUna, Jord., from British New 

 Guinea. 



Delias caroli, Kenr., inhabits the Arfak district, and a long 

 series was received from the Angi Lakes. It is represented 

 in the Wandammen district by the form shown, and this is 

 another illustration of the local distribution of Delias in New 

 Guinea. 



Delias thompsoni possesses a pattern distinct from any other 

 in the genus. 



Leuciacria acuta, Roths, and Jord. Described from British 

 New Guinea. We received a long series from the Arfak. 

 Ideopsis vitrea f. serena is nearest arfakensis, Fruh. 

 Morphotaenaris schonbergi f. kenricki inhabits the Arfak 

 district. From the Wandammens we have a darker race 

 which we have named loandammenensis. 



Erycinidia maudei is unlike any other species in this curious 

 genus. 



Platypthima pandora is allied to a new form sent by Messrs. 

 Pratt from the Arfak.
