agrees precisely with Reeve’s types, excepting that the aper-

I. Introduction. 
The following notes on the habits of butterflies are chiefly 
from observations made in British North Borneo. They 
were mostly written in the jungle, and every observation was 
recorded at the time. I was often for days amid such a wealth 
of gorgeous Ornithopteras and Papilios, &c., that any little 
point suggested while writing could be observed and any 
ambiguity be corrected without leaving the open-sided hut. 
This, however, is unhappily a rare chance, and seldom lasts 
long at a time. 
Il. The Hours of Appearance and General Habits. 
As a rule our butterflies do not come out until about seven

which I now forward for publication —W. L. Disranr. |
