good collecting centres are Trincomalie, Dambool, Tissamaha- 
rama, Madampe, Elephant Pass and Tangalle. 
The best baits I know are: Ist. Small pieces of sponge 
soaked in toddy, in whicha little jaggery has been dissolved. 
Pin these to trees, or lay them on rocks in likely places. A 
screw top jam bottle is the best thing to carry them in. 
Squirrels are very fond of toddy, and will eat the sponges if 
left unwatched. 2nd. Treacle, or jaggery boiled in beer, 
with a good dash of rum added just before use. This is best 
for Kallima and Charaxes. 3rd. Overripe fruit, especially 
jak. This is best for Discophora. 4th. A dead specimen, 
pinned on a twig, will often attract the males of its species 
within reach of the net. 
In the frontispiece I give an illustration showing the names 
of the various parts of a butterfly’s wings as used in Col. 
Bingham’s work. 
For assistance in writing these notes I am much indebted 
to the following :— To the Hon. Mr. F. M. Mackwood, whu 
has for over 30 years always given me the benefit of his 
experience, and has been very liberal in supplying me with 
varieties. To Capt. Norman D. Riley of the British Museum 
(Natural History) for reading the manuscript, and giving 
me all the help in his power in bringing the nomenclature 
up-to-date, and identifying several species for me. To Lt.-

in many ways. _
