The type-sijecimen of this .species is still preserved in the Banksian collection. 



P. peranthus occurs in Java, on the lesser Snnda Islands as far east as Adonara, 

 and on the small islands south of Celebes and Saleyer. In Celebes, Timor, Timor 

 Laut, the .Moluccas, and New Guinea it is represented by other, but closely allied- 

 species. 



At present there are three local forms of P. peranthus Fahr. known, namely : — 



(rt) : P. pieranthus Fabr. from Java ; 



(6) : P. peranthus intermedins Snellen from Tanah-Djampea ; 



(c) : P. peranthus fulgens Rober from Bonerate, liombock, Sambawa, Suniba, 

 Flores, Pm'a, Adonara. 



The P. perldes Wall, from Timor, Wetter, ;ind the Tenimber Islands is ap- 

 parently constantly different fi-om T. peranthus in the much greater extent of the 

 greenish blue colour of the forewings ; and it is very remarkable to note that 

 P. peranthus fidgens, which geographically stands intermediate lietween peranth/ts 

 and pericles, has the bluish green area more restricted than typical peranthus has. 

 As the green-blue area of the wings is not constant either in pieranthus or pericles, 

 it is probable that further researches on the lesser Sunda Islands will procure material 

 which links the two species together. I have already two specimens without proper 

 locality which are almo.st as blue as pericles, and have the greenish blue area more 

 extended than peranthus has, but much less than pericles ; the cottony patches 

 on the forewings of these two examples resemble more those of pericles than of 

 peranthus, consisting of three separate stripes. I refer for the present the two 

 specimens to P. peranthus Intermedins Snellen, to which they come very near, 

 according to P. C. T. Snellen who has kindly examined thein. 



The Celebesian P. adamantius Feld., as well as the Moluccau P. lorquinianus 

 Feld., are not connected by any intergradations with P. peranthus Fabr., and differ 

 much more from that species than P. pericles Wall, does, so that I do not hesitate 

 to enumerate them as distinct species. 



(a); P. peranthus Fabr., forma typ. [(?,?]. 



The bluish green area of the forewings, which in .some examples is more blue 

 than in others, extends about to the origin of the first median nervule. The cottony 

 l)atch on the forewings of the male consists of four streaks which are entirely, or 

 almost entirely, merged together, and of a separate narrow streak upon the upjjer 

 median vein.
