A REVISION OF THE PAPILIOS OF THE EASTERN 



HEMISPHERE, EXCLUSIVE OF AFRICA. 



By THE HON. WALTER ROTHSCHILD. 



WHEX I first began the iuvestigatiuns which form thu foniidation of this 

 article, I had intended to give a revision and bibliographical and S3'nonymical 

 list of the Bkojxilflceni of all the islands cast of " Wallace's Line," which passes 

 between the islands of Bali and Lombok. 



This revision wonld have been fonnded, as is to a great extent the present one, 

 ou the collections made in the Indo- and Anstro-Malavan regions by the celebrated 

 American collector Mr. William Doherty. 



However, when I came to work out some of Mr. Doherty's large and magnificent 

 collections, I was very much startled to find that the synonymy and bibliography 

 of the Lepidoptera were so involved and so fnll of errors, that a complete and in all 

 respects scientific revision of the B/wjjaloeera of these numerous islands would 

 necessitate more or less a complete reference to the Rhopalocera of the wliole of 

 the old world. I therefore gave up my idea, and determined to give a series of 

 monographic revisions, dealing with a few families both of Rhopnioce.ra and 

 Hvterucera from the whole world, and only in such cases where I either possess 

 one of the best collections of these families, or am jiarticnlarly interested in such 

 families. In each case the revision or series of revisions of the species belonging 

 to a family will be followed by a final generic revision. 



In the present as well as in all future revisions, scrupulous attention has and 

 will be given not only to the synonymy and bibliography, but to the structure, 

 neuration, scaling, scent-organs, etc., so as to base the final generic revision on as 

 wide a basis as possible. 



I had hoped when I began this paper to carry out all the necessary investi- 

 gations and examinations of material myself; but as the work proceeded I found 

 that it involved such a vast amount of time that I was obliged to call in the 

 help of Dr. Jordan, the Entomologist of the Tring Museum. 



Dr. Jordan has gone through the bibliography for me, and also has visited, both 

 together with me and alone, the collections of the Britisli Museum, Messrs. Salvin 

 and Godman, Mr. H. Grose Smith, Mr. Herbert W. Adams, Mr. ('rowley, and 

 others ; and if it had not been for his help and care, I am afraid many years would 

 have gone by before I could have even attempted to carry out this work. 



Throughout the work will be found a number of notes by Dr. Jordan, dealing 

 with our metliods of investigaliou, such new or unfamiliar facts as have presented 

 themselves to us, and, lastly, detailing the scope of the present article.
