Allied to >S1 Treitschkei of New Ireland, h (for mis of Duke- 

 of-York Island, and ce^m of the Solomon Islands ; but differ- 

 ing constantly from all three (in both sexes) in having two 

 unequal subapical white spots on the upper surface of the 

 primaries, and no spot on the first median interspace, the two 

 upper spots of the triangular group in 8. Treitschkei being- 

 alone present j the interno-median elongated spot is consider- 

 ably smaller and shorter than in any of the species ; the first 

 three of the discal series of spots on the secondaries of the 

 female are generally much enlarged, and two of them are 

 frequently present on the male secondaries. In the dark blue- 

 black colouring of the male the species most nearly approaches 

 S. biformis) but the pattern of the under surface (with the 

 exception of the subapical spots on the primaries) agrees with 

 S. Treitschkei. Expanse of wings 84-95 millim. 



Ten specimens. u Dentrecasteaux Island, Admiralty 

 Group"*. 



It is evident that each island, or at least each group of 

 islands, has a separate species, constantly differing, although 

 in apparently insignificant characters, from its nearest allies. 

 To those who have not specially studied the Euploeinse the 

 presence or absence of two white spots on the primaries would 

 appear to be a variation scarcely worthy of remark, much less 

 of specific value ; nevertheless it is perfectly clear that the 

 form having these spots is characteristic of the island where* 

 it occurs, and therefore to record one of the Admiralty Islands 

 as a locality for S. Treitschkei would not be in accordance with 

 exact scientific fact. We might say that a local form of the 

 latter species was found in the Admiralty group, a second in the 

 Solomon group, and a third at Duke-of-York Island; but the 

 rapid increase of our collections of Lepidoptera proves more 

 and more clearly that the genera consist of nothing but grada- 

 tional series of local forms in this Order; and therefore, if we 

 call the species local forms, we may call the genera species. 

 To such a course no living Lepidopterist would consent.
