( 267 ) XVIII. A list of the Lejndojjtera of the Khasia Hills, Part I. By Colonel Charles Swinhoe, M.A., F.L.S., &c. [Read March 29tli, 1893.] For the past three years I have received monthly consignments of Lepidoptera from the Khasia Hills, captm*ed by the native collectors of the Rev. Walter A. Hamilton, and, as he employs several collectors, this list ought to be fairly complete, and I have thought it worthy of publication, because there seem to have been fewer Lepidoptera recorded from the Khasia Hills than from almost any" other locality in India. The new species in the Ehopalocera are, as might be expected, but few ; in the Heterocera there are very many. I have followed Moore's classification in the Euploeince and Satyrince, de Niceville's in the Nympha-lince and Lycmiida, and Watson's classification of the Hesperidce (P. Z.S., 1893, p. 3), to whom I have sub-mitted all my new species of Hesperida for examination, being the latest classification recognised by Indian lepi-dopterists. In the Pierince (which are very limited), and the Papilionince, I have followed the arrangement in my own museum. In the Heterocera, I have followed Hampson's classification of the Sphinges, Bombyces, Noctues, and Deltoides, and Meyrick's classification of the Geometers and Pyrales, altering the order in which they run to suit the present knowledge of the subject. .
