THE ANNALS AND MAGAZINE OF NATURAL HISTORY. [SIXTH SERIES.] No. 101. MAY 1896. XLVI. — On new Species of Coleoptera from Japan , and Notices of others. By G. Lewis, F.L.S. Towards the close of last year Monsieur Ren^ Obertlmr sent me some Coleoptera from Oshima, and on examination I find the species generally are of a decidedly more tropical character than those of the most southern parts of Kiiishiu. I once spent three or four days in Oshima in February ; the diurnal Lepidoptera were then flying freely, and the temperature and climatal conditions generally seemed to me to harmonize with those of May in Nagasaki. Oshima lies in lat. 28°, and Nagasaki is close to lat. 33°, and the warmth of the ocean, as well as the more direct rays from the sun, has a very marked effect on the vegetation of the small oceanic islands to which Oshima belongs. Near Yokohama the warmth of the Kurosuwo, or Japanese Gulf-stream, is distinctly felt on the Idzu peninsula, while in the bay of Tokio the water is of a lower temperature ; this and similar agents in various parts of Japan have without doubt a localizing effect on peculiar species, and until almost every valley and mountain-side have been searched at various seasons of tlie year, the Coleopterous wealth of the Empire will continue to yield sufiicient novelties to reward one whose care it may be to seek them.
