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.
