With the exception of the typical jupker and sempronius 

 the forms of this group are still rare, and some interesting 

 results are to be expected from an exploration of the higher 

 lands in the interior of the large islands. 



Since this paper was prepared, another distinctly new 

 Delias has been received from Ceram. This will be incliuled 

 in a second paper. 



The illustrations accompanying this paper are excellently 

 produced from photographs taken by Mr. H. Campbell, who 

 is in charge of the photographic department of the Hill 

 Museum.
