PJ^EFACE TO VOL« 11. 



Some explanation appears to me to be due to the subscribers to " The Butterflies of 

 India, Burmah and Ceylon" as to the delay which has taken place in the publication of this 

 volume. The second part of the first volume was issued in August, 1883, soon after which 

 date Major Marshall obtained twenty months' sick leave to Europe. He took away with him 

 the rou"hMS. of this volume, hoping to be able to continue the work at home, but ill- 

 health prevented him from doing so. He returned to India in March, 1885, but the un- 

 certainty of his health even then made it doubtful whether he would ever be able, in addition 

 to his official duties, to conduct to a successful issue a work of this magnitude, and as the 

 publication had already been delayed nearly two years, he most reluctantly decided, in the 

 interests of the work, to abandon his share in it, and, on my expressing my willingness to con- 

 tinue it alone, he forwarded to me all the papers and drawings connected with the publication. 

 Since that date (March, 1885) I have worked steadily and unremittingly at this volume. 



It has been a source of great disappointment to me that Major Marshall should have been 

 obliged to retire from the work, and that my name alone should appear on the title-page, 

 especially as his retiring has been so far more nominal than real; every word of the MS. 

 and two proofs have been carefully revised by him, and in every way he has rendered me 

 the greatest assistance and encouragement, and has promised most kindly to continue his 

 valuable help in the future as far as he is able to do so, I can only express a hope in con- 

 cluding this matter that my readers will not find any falling off in interest or less accuracy 

 in the" matter contained in the second than obtained in the first volume, and my deep 

 indebtedness to Major Marshall for his invaluable assistance and advice. 



It is my pleasing task to convey my best thanks to the following gentlemen for assistance 

 given, either with specimens or information, during the preparation of this volume, in addition 

 to those mentioned in the preface to the first volume :— To Colonel C. Swinhoe I am indebted 

 for the loan of specimens from his collection, and also for carefully going over all the proofs 

 of this volume and adding many useful notes ; to Colonel A. M. Lang, R.E., for the use of 

 his large collection ; to Mr. Otto Moller for the loan of any specimens I required from his 

 mafrnificent Sikkim collection, now numbering some 500 species ; and for the gift of specimens 

 from Mr. W. H. Irvine from the Malda district ; Major E. Y. Yerbury from the Punjab ; 

 Mr. A. V. Knyvett from Bhutan, where he has recently obtained Stkhophthalma noiirmahal, 

 (previously only doubtfully recorded from India), the new Lethe hisanda, and Kallima knyvetiii, 

 and the rare Stibooes nymphidia and Annandia huderdalii ; to Mr. E. H. Man for many rare 

 species from the Nicobars ; Mr. R. Wimberley for Andamanese specimens ; Mr. J. A. Betham 

 from Central India ; Mr. J. L, SherwiU from Assam ; Lieutenant E. Y. Watson from Beluchistan 

 and Burma • Mr. W. C. Taylor and Mrs. Wylly from Orissa ; Mr. W. F. Hampson from the 

 Nilgiris • Father D. Honore from extreme South India ; and to the Bombay Natural History 

 Society for the gift and loan of specimens. Lastly, I have to express my most grateful thanks 

 to the Superintendent of the Indian Museum, Calcutta, for the facilities he has afforded me, 

 ^Yithout which it would have been impossible to have carried on the work. 



In conclusion, I would express a hope that the succeeding volumes of this work will be 

 issued at shorter intervals than the two first have been, and that the public, professionals and 

 amateurs alike, will extend to this volume the same indulgence as they have shewn to the first, 

 remembering that it is the product of scanty leisure, and carried through in the face of many 

 difficulties and in a trying climate. ^
