both the white spots are spread out into peculiar streaks (see PI. XII, fig. id, 

 PI. XIII fig. 15^). 



This peculiarity, however, is not confined to them since they agree in this 

 respect with several other species peculiar to that island so that when they 

 are compared with each other they all clearly exhibit a special Celebes facies 

 to an expert Lepidopterologist. Similarly when the Euploeas occurring in the 

 Philippines are compared with the same species from other islands of the 

 archipelago a special Philippine type can be recognised in them, in this case, 

 however, rather on account of the size and increased number of the white or 

 bluish-white spots especially in the apical portion of the fore-wings. The most 

 notable example of this may be observed in the K6 islands. Three species 

 of EuPLOEA occurring in Java under the names of E. Leucostictos Gm., 

 E. Mazares Moore, and E. Ci imena Cram, are met with in those islands in 

 the forms called E. Assimilata Felder, E. Hopferi Felder, and E. Eurypon 

 Hew, all differing from the Javanese forms in the same manner in having a 

 very broad white margin round both wings, a feature which also occurs in 

 some other islands, such as Banda, but neither in Ambon, Buru, nor New Guinea. 

 As regards E. Climena Cram., entirely brown specimens marked with some 

 white dots (PI. XI fig. \d) and others with partly white hind- wings (PI. XI fig. \B) 

 occur intermixed in Java, the specimens from Bavvean agreeing with the former 

 as do those from Ambon, (PI. XI fig. \c) while those from Flores, on the other 

 hand, have the white on the hind-wings as a part of the Javanese; in this species, 

 therefore, an evolutional diffusion of white exists which occurs in varying degrees 

 but reaching its climax in the Ke and some other islands. In the K6 islands 

 this is, indeed, the case with all these three species and, in addition, with butterflies 

 of other genera. Hypolimnas Anomala Wall (Antiopa Cram.) is a Nymphalid 

 of wide distribution in the Malay Archipelago which has assumed the type of 

 colouring of Euploeas, differing in this respect from the other members of the 

 genus to which its belongs, and thus, following in the same direction in the 

 process of colour evolution, beginning to exhibit, in the same manner as 

 Euploeas, in different districts a larger or smaller number of white spots, 

 especially on the under side of the hind-wings. In the islands referred to this 

 species acquires, just like the said Euploea species occurring there, a broad 

 white margin round all four wings. Moreover in a species of Danais, D. Schenkii 

 Koch, from the same islands white makes its appearance in a striking manner ; 

 the large Saturnia occuring there is also much more whitish than its allies in 

 the other Malayan islands. 



On taking these facts into consideration it cannot be doubted that they are 

 all of the same nature and must, therefore, be attributed to a common origin.
