PLATE XXXI. 
ILLUSTRATION OF A NEW INDIAN SPECIES OF PAPILIO. 
The beautiful species of Papilio figured in the acccompanying 
plate belongs to Boisduval’s seventeenth group of the genus ; but 
is distinguished from the majority by the great elongation and 
narrowness of the wings, and the very broad and spatulated tail; 
and from all, by the bright red base of all the wings on the under¬ 
side. It is most nearly related to the two species P. Philoxenus 
and P. Minereus of Gray (Zool. Misc. p. 32), which were de¬ 
scribed from unique specimens contained in General Hardwipke’s 
collection now at the British Museum, namely, a male of the for¬ 
mer and a female of the latter species. From this circumstance, 
united with the evident relationship between the insects, M. Bois- 
duval was induced, in his “ Histoire Naturelle des Lepidopteres,” 
to consider these two individuals as the sexes of one species, for 
which he retained the name of P. Philoxenus. The collection of 
Assamese insects formed % Mr. Griffith, now in the possession of 
R. H. Solly, Esq., and that forwarded from Sylhet to the Rev. 
Mr. Stainforth, now in the possession of Mr. H. Doubleday, have 
enabled me to determine the specific distinction of the two species ; 
and as there is no figure of either (except the wretched one of 
Minereus given by Donovan, Naturalist’s Repos., vol. 4, pi. 140, 
which Boisduval has omitted to quote), I propose to illustrate them 
a future number of this work. The following are the characters 
cf the new species figured in the accompanying plate, which was 
also contained in Mr. Stainfortli’s collection, above mentioned.
