Hah. — Java, Borneo, Singapore (Wall.) ; Sumatra (Veil.). 



This species presents slight but apparently permanent cliffe- 

 rences in each locality. Taking tliose of Java as the type, the 

 Singapore form has a narrower black border to the hind wings, the 

 outer red spot is wanting beneath, the three inner red spots are 

 much larger, and the anal margin is of a deeper yellow colour. The 

 Borneo form lias no black hind border but a broad ashy one, 

 while beneath it is intermediate between the preceding and the 

 type. Both however are larger, and have more elongate wings 

 than the Java specimens. 



Vollenhoven gives " Ceram" as another locality, but this is evi- 

 dently an error.

Hah. — Luzon, Philippines (Coll. Wall., B. M.). 



" A geographical form of P. liyparde'' (Feld.). This has 

 broader wings than the other forms, but is hardly more distinct 

 than those of Sumatra or Borneo.

i/a/j.— Celebes, Macassar (Wall.) ; Menado (Voll.). 



A most beautiful and distinct species, excelling all others of 

 this sub-group as those of Celebes so often excel their allies. 

 Dr. Felder's name for this species is, I believe, of a later date than 

 Vollenhoven's, though the two publications are of the same year.

 Hub. — Banca (Leyden Mus.). 



This very interesting species shows that the little island of 

 Banca, though separated by a narrow strait only from Sumatra,
