Habitat. — N.W. Himalayas, Buima, Aunam, Toukin, China. 



Distribution. — We possess examples from Simla, Sikkim, Assam, Bhootan and 

 IMandalay ; there are several examples from China in the British Museum ; it does not 

 appear to occur in central or upper or western China. Leech makes no mention of any 

 species of Ixias in his Butterflies of China, Japan, etc. There are many examples in 

 Colonel Swinhoe's collection from Tonkin and Annam, received from Fruhstorfer as 

 7\)nkiniana which can in no way be separated from Indian examples. 



JVote in the type specimen of Ixias Pyrcne by Professor Aurivillius : — 



"The specimen of Papilio Pyreue named by Linnaeus in Mus. Ulricse, p. 241 

 (1764), does not now exist. In 1803 King Gustavus IV. Adolphus made a gift of the 

 Cabinet of Louise Ulrica to the University of Upsala, of which Thunberg made a List, 

 l)ut in this List Pyrcne. does not figure, so it was already then spoiled or lost, and 

 Professor Aurivillius (Kongl. Sveuska Veteus.-Akad. Handl. 1882, p. 54) has treated it 

 only by the description made by Linnaeus." (Professor Aurivillius in letter from 

 Dr. F. A. Bcrgstcdt, Lilnarian, Kongl. S. Vet.-Akad. Bibliotek ; Stockholm, 

 March 8th, 1907).
