Found only at high elevations, not below 3,000 feet, on the Central 
Plateau and in the Gayoe mountains, throughout the year, but most 
abundant in December and January, in which months the Battak col¬ 
lectors brought in hundreds of males. This butterfly, like species of 
Char axes , very easily rots, as all specimens brought from the moun¬ 
tains if not properly dried at once in the sun or by the fire fall to 
pieces. Rothschild records this species from Sumatra as (6), P. agetes 
insularis , Staudinger.

near the sea in April, and one from near Selesseh in June. Dr. Hagen 
had only one specimen from the Gfayoe-lands. Rothschild records it 
from Sumatra as (d), P. aristeus hermocrates , Felder.
