INTRODUCTION. XV 



acquired the MSS. of the volumes on the Papilionidce, Pieridce 

 and Hesperiidce left partially incompleted at Mr. de Niceville's 

 death. These MSS. have been generously placed at my disposal 

 for use in the compilation of the future volumes of this work. 



In connection with this, I ought to add that the unique 

 collection of Indo -Malayan Lepidoptera brought together by the 

 late Mr. de Niceville was acquired some little time before his 

 death by the Indian Museum, and that through the kindness of 

 Major Alcock, I.M.S., C.I.E., F.R.S., Superintendent Indian 

 Museum, I have had the privilege of examining many of the 

 types. 



A few words with regard to the illustrations. This is the first 

 volume of the Fauna series which has had any large number of 

 coloured plates. The ten in this volume have been well executed 

 by Mr. Horace Knight, and reproduced by the modern process of 

 colour-printing which is getting rapidly perfected.
