2. Papilio ulysses denticulatus, subsp. nov. 



This form shows a transition to ambiguus, Roths., from 

 the Bismarck Islands. 



<$. Fore-wing with the blue beyond end of cell reduced to a few 

 scales or a spot at the base of 6 ; spot above cell in 9 small or absent, 

 spot in 5 minute or absent, the one in 4 small. Hind-wing with 

 the blue area strongly dentate, the prolongations being between 

 the veins and not along them as is the tendency in most of the 

 forms. 



$. Fore-wing with all spots outside cell above vein 4 absent. 

 Hincl-iving with long denticulations in cellules 3-5; submarginal 

 spots smaller than in autolycus and almost as much reduced as in 

 ambiguus.

3. Papilio codrus schoutensis, subsp. nov. 



This form is distinguished from typical medon, Feld., 

 in the much reduced and more sharply defined costal 

 spot on the hind-wing below, and in the band becoming 

 obsolete. 



One specimen approaches specimens of medon from 

 Mefor in which the band is partly washed out, but the 

 costal spot is larger than in these, being more typical; 

 there are two similar specimens from Biak in the Tring 

 Museum. Examples from Waigeu are more typically 

 medon than those from Mefor. 



A series of both sexes. 



Danainae. 



4. Danaida marcia, sp. nov. 



(Plate III, fig. 1, $.) 



This rather distinct species is apparently most nearly 

 allied to rotundata, Gr.-Sm., from the Bismarck Islands. 



cJ $. Ground-colour blackish-brown, markings white. Fore- 

 wing. — A stripe in lower part of cell between veins 2 and 3; a 

 small subcostal spot in cellule 10, a smaller one beyond it in 9 

 and just above the first of 3 post-cellular spots in 4-6, the middle 

 one the longer, and the one in 4 shortest and nearly square; an 

 oblong patch in 2, pointed towards angle of 2 and not touching 

 cell; a small spot above it in 3 near cell; a stripe in 16 on sub- 

 median, nearer to base than to margin, and anteriorly convex;
