P. sarpedon, Linneus, Syst. Nat. Ins., ed. x, p. 461, n. 14 (1758). 
The very remarkable melanoid aberration or “ sport” of P. sarpedon figured was 
obtained on the Battak Mountains of Sumatra by Dr. Martin’s Battak collectors, 
The upperside of both wings is entirely black, save in the forewing the anterior 
spob of the broad macular discal blue-green band of normal P. sarpedon, and in 
the hindwing the four middle submarginal blue-green lunules of the series of six 
of the typical form, are alone present. The markings of the underside similarly 
differ, the broad discal blue-green band of both wings of the normal form 
being reduced to the anterior spot of the forewing only, the submarginal lunules 
of the hindwing as on the upperside, but all the crimson and deep black mark- 
ings of the normal P. sarpedon are present. 
This unique butterfly is in Dr, Martin’s collection.
