A List of the Lepidopterous Insects collected by Mr. Ossian Limborg in Upper Tenasserim, with Descriptions of new Species. By F. Moore, F.Z.S., Assistant Cura-tor, India Museum, London. [Eeceived September 17, 1878.] (Plates LI.-LIII.) This list comprises the Lepidopterous portion of the collection made on and around the Moulayet range in Upper Tenasserim by Mr. Limborg, who was accompanied by Mr. Wood-Mason's native collector, Motiram. The party proceeded, about the middle of December 18/6, from Moulmein up the Houngduran, collecting as they went along to the Hills, on and around which, and along the banks of the river leading to them, the whole collection was made.
