V.— DESCRIPTIONS OF NEW FORMS OF 

 LEPIDOPTERA FROM THE ISLAND OF HAINAN. 



By J. J. JOICEY and G. TALBOT. 



The forms here described were sent to the Hill Museum by C. T. 

 Bowring, Esq., F.E.S., who, whilst residing on Hainan, spared neither 

 trouble nor expense in obtaining specimens from all parts of the island. 



We have to acknowledge our great indebtedness to Mr. Bowring 

 for his generosity in presenting to the Hill Museum the bulk of the 

 specimens obtained by him between the years 1918 and 1920. At Mr. 

 Bowring's request a selection of duplicates will be presented to the 

 National Museum. 



The work of classifying this extensive material is proceeding, and 

 a complete account of the Lepidoptera of Hainan will be published 

 in a future number of this Journal. Mr. Bowring has added very 

 largely to our knowledge of the Hainan Lepidoptera by the discovery 

 of many forms hitherto not known to occur on the island. Some 

 of these are new to science and in the present paper we record 22, 

 together with the other sex of 4 already described in the $ . 



Special mention must be made of the collection obtained by Mr. 

 Young Chun, a Chinese graduate of Harvard University, who made 

 a journey of three months in the Five Finger Mountains. Although 

 Mr. Chun was especially engaged upon botanical work, he managed to 

 get together a very fine lot of Lepidoptera for Mr. Bowring. These 

 included an interesting new form of Kallima inachis, a new Tagiades, 

 and new forms of Limenitis dudu, Hestina nama, and Stichophthalma 

 nourmahal, none of which were received from other parts of the 

 Island. Mr. Chun also obtained the extremely rare Pier is naganum 

 Moore, only known from the Naga Hills and Upper Burma.
