•(«): P. neptunus Gu«-., forma typ. [<?,?]. 



In Delessert's Souv. Voy. Ind. the plates 19 and 20 are erroneously lettered 

 satumus (19) and ne.ptunus (20) res[)ectively, instead oVneptunus (19) and mtv.rnim 

 (20). 



The number of spots composing the red patch on the hindwings is inconstant ; 

 below, the spots are much dusted with black scales. The specimens with two red 

 spots only are Hagen's sumatramw.

This aberration is not confined to Sumatra, lint seems to be there the usual form.

White bands of the forewings strongly .suffused with black. 



The red patch on the forewings consists above mostly of two spots only, which 

 are rather small, and vary in colour from red to buflf.

This species does certainly not occnr in Borneo (cf. De Haan, I.e.) ; if there is 

 any representative in Borneo, it will most jirnbablv be more closely allied to sycorax 

 Urose Smith than to prinpvK Koisd.
