Tonkin iana which can in no way be separated from Indian examples. 
Note in the type specimen of Ixias Pyrene by Professor Aurivillius : — 
“The specimen of Papilio Pyrene named by Linnseus in Mus. Ulricas, p. 241 
(1764), does not now exist. In 1803 King Gustav us IV. Adolphus made a gilt of the 
Cabinet of Louise Ulrica to the University of Upsala, of which Thunberg made a List, 
but in this List Pyrene does not figure, so it was already then spoiled or lost, and 
Professor Aurivillius (Kongl. Svenska Vetens.-Akad. IJaudl. 1882, p. 54) has treated it 
only by the description made by LiniueusP (Professor Aurivillius in letter from 
Dr. F. A. Bergstedt, Librarian, Kongl. S. Yet.-Akad. Bibliotek; Stockholm, 
March 8th, 1907).
