Common in the low valleys from April to October. In 
identifying the Sikkim form with P. Hurypilus of 
Linneus I follow Messrs. Wood-Mason and de Nicéville, 
who say that the one found in Cachar agree with Clerck’s 
figure of the type of this species, except in being a little 
larger, and have the discal macular band even wider. 
Distant says that the typical Hurypilus is found in the 
eastern islands of the Malay Archipelago, and, not 
satisfied with the numerous names which the older 
authors and Felder have already given it, adds another. 
My own series contains four specimens from Sikkim, three 
from Bhotan, one from Cachar, one from Calcutta, three 
from the Andaman Islands, three from the Nilghiri 
hills, four from Tenasserim, and four from the hills on 
the frontier of Siam and Burmah. Among these I find 
no constancy. The Himalayan, Cachar, and Andaman 
specimens are generally rather larger, and have broader 
bands than those from S. India, Tenasserim, and Siam, 
which have been distinguished as telephus and doson. 
The character by which mecisteus is distinguished, 
namely, the junction of the short red-spotted costal 
band of the hind wing below with the longitudinal band 
of the inner margin, is variable, especially in Sikkim 
specimens. Before the various names quoted above can 
be recognised by me as distinct species, it will be 
necessary for those who make no allowance for varia- 
tion to define the various forms, and show that they are 
confined to certain areas.
