A large collection of Butterflies was sent to the British Museum in 1905 made by various officers who took part in the Tibet Frontier Commission in 1903 and afterwards accompanied the Expedition to Lhasa. The localities in which they were taken have been so fully described by Capt. H. J. V/alton, who was Medical Officer and Botanist to the Commission, in ‘ The Ibis' for January 1906, that I need not say much about the country ; but remembering that the expedition was, during a large part of the time, in a state of actual warfare and that there was no entomologist with the party, it will be understood that this collection must be regarded as only representing a part of the species which exist there. The localities are as follows:-Tungu, a valley near the head of the Lachen River in Native Sikhim close to the Tibetan frontier, elevation 15,000-16,000 feet; Lhanak, a valley to the west of this at an equal or greater elevation ; Khamba Jong, a Tibetan fort fifteen miles beyond the Kongra-lama Pass, at an elevation of 15,000-16,000 feet, where the Commission stayed during the summer of 1903 ; on the march from Phari to Gyantze in June and July 1904 ; Gyantze, where the Mission was besieged for some time and the greater part of the insects were collected ; and at and near Lhasa, where a few specimens were afterwards taken in August. With a few exceptions most of the species enumerated are known to occur in Ladak. My paper on Butterflies from Sikhim, P. Z. S. 1882, p. 398, should be referred to; also Col. Fawcett's paper, op.cit. 1904, ii. p. 134. 1. P a p il io m a ch ao n var. s ik k im e n s is Moore, J. A. S. B. 1884, p. 47. Seems to be common in Alpine Sikhim and at Khamba Jong; some specimens have shorter tails than usual, approaching the variety laclakensis Moore. 2.
