The species wasfound upon the plateau of the Neilgherries near Otacamund andKotirghery, by the zealous traveller in honour of whom it has beennamed. M. Guerin describes the posterior horn of the head asbeing plate, dirigee en avant et en bas, aplatie ; not noticing itstriangular shape, which is most singular, when it is considered thatthe insect is a female, and that the females of the other species ofthe genus have this horn truncate. The plants figured in Plates 29 and 30 are two fine species of Cypripediutn; that in theformer Plate being C. venustum, (a native of Nepaul) drawn from a specimen which blos-somed finely in the Botanic Gardens at Kew, at the beginning of the present year; and Plate30, representing the Indian Cyp. 123 PLATE XXXI. ILLUSTRATION OF A NEW INDIAN SPECIES OF PAPILIO. The beautiful species of Papilio figured in the acccompanyingplate belongs to BoisduvaFs seventeenth group of the genus ; butis distinguished from the majority by the great elongation andnarrowness 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. Philoxenusand P. Minereus of Gray (Zool. Misc. p. 32), which were de-scribed from unique specimens contained in General Hardwickescollection 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, forwhich he retained the name of P
