xii PREFACE, 
that he has given me from the Khasi Hills, where he has employed many native collectors for 
the past two or three years, during which period he has discovered many species new to 
science (which I have had the pleasure of describing), besides obtaining beautiful series of many 
species that had hitherto been very rarely met with in collections. He has carried his genero- 
sity in many instances so far asto present me with unique specimens. Mr. P. W, Mackinnon 
too has aided me largely by the gift of splendid series of specimens from Masuri and from the 
inner ranges of the Western Himalayas extending up to the sources of the Ganges and Jumna 
rivers. For the gift of many butterflies, larvae, and’ pupz, I am indebted to Mr. E, A. Minchin, 
who has shewn a remarkable aptitude for the discovery of the two latter stages, especially in the 
family Zycenide with which this volume deals, nearly all the larvze and pupz described therein 
for the first time having been discovered by him at Barrackpore near Calcutta. Unfortunately 
for me, he was only able to help me in this way for about a year, after which he left India for 
Oxford. Colonel C. Swinhoe also has very kindly allowed me the use of his collection of 
Lycenide, which is especially rich in species from the Bombay Presidency. Lastly, I have to 
thank Mrs. Wylly, Messrs. C. G. Blathwayt, E,H. Aitken, G. F. Hampson, J. Davidson, 
F, Fairlie, E. E. Green, B, Noble, and W. Davison for the gift of many specimens. 
To Dr. G, King, C.I.E., the Superintendent, and to Dr, D. Prain, the Curator of the 
Herbarium, of the Royal Botanical Garden, Calcutta, who have most kindly named most of 
the plants on which the larve described in this volume feed ; as well as to Dr. A. Forel, of 
Geneva, who has carefully named the various species of ants that attend many of the larva ; my 
thanks are also tendered. 
I propose, immediately after this volume is published, to take up the next, which will con- 
tain the family Papz/ionide, and I trust that I may be able to finish it in less time than its 
predecessors have taken. :
