New Lepidoptera from the Island of Hainan. — Mr. G. 

 Talbot, on behalf of Mr. J. J. Joicey exhibited numerous 

 specimens of new Lepidoptera from the island of Hainan, and 

 made the following observations :— 



During the years 1918, 1919, and the present year, the Hill 

 Museum has received large collections of Lepidoptera from 

 Hainan. These have been obtained by and through the 

 exertions of Mr. C. Talbot Bowring of Hoihow. This gentle- 

 man has very generously presented all the specimens to the 

 Hill Museum on condition that a catalogue of all the species 

 would be prepared. We propose, therefore, to publish a 

 . complete list of the Lepidoptera from this island, and this we 

 should have resolved upon doing in any case, because the 

 collections sent by Mr. Bowring have increased enormously 

 our knowledge of the number of forms already known to exist 

 upon the island. 



Mr. Bowring has spared no effort and expense to obtain 

 specimens from different parts of the island. During the 

 spring of this year, Mr. Young Chun, a Chinese graduate of 

 Harvard University, was in Hainan collecting plants. He 

 made a successful expedition to the Five-Finger Mountains 

 in the country of the Loi savages, where the explorer Whitehead 

 lost his life. Mr. Chun very kindly handed his collection of 

 Lepidoptera to Mr. Bowring for transmission to us. 



Although something is known already of the forms inhabiting 

 these mountains, through the efforts of Whitehead and of a 

 Japanese collector sent there by Lord Rothschild, the col- 

 lection made by Mr. Chun contains some interesting novelties, 

 chief among which is a form of Kallima inachis. The collection 

 is not yet worked out and may contain other new forms. The 

 same must apply to a mass of Mr. Bowring's material. 



The following forms are shown : — 



Papilio hipponus howringi Prout ; P. dialis cataleucas Roths., 

 with the hitherto unknown female; P. rhetenor Westw., 

 subsp. nov. ; P. castor hamela Crly. ; P. aristolochiae gonipeliis 

 Roths., with its mimic P. polytes L. ?; the aberration asireans 

 Jord. of polytes; Pieris nagonum Mre.; Danaida sila Koll.,
