ME. H. W. BATES ON THE 



American genera (e. g. Asemum, Teh-opium, Bhagium, Ency- 

 clops, PacJiyta, Grainmoptera, Gmirotes, Strangalia, Necydalis, 

 Sosalia, &c.) having been now found, and many of the absolutely 

 new genera having palsearctic or nearctic rather than tropical 

 affinities. We know at present too little of the productions of 

 the neighbouring regions of Asia (^. <?. Corea, Manchuria, and 

 Northern China), to discuss profitably the interesting problems 

 which the Insect-fauna of Japan presents, such as its true rela- 

 tions to the neighbouring temperate parts of the Asiatic con- 

 tinent and the more distant tropics, and the derivation of the ex- 

 traordinary number of endemic forms which it seems, especially as 

 regards the Longicornia, to contain, Mr. Lewis's recent journey 

 has shown, amongst other things, that the tropical forms are not 

 confined to the southern part of the islands, nor the boreal forms 

 to the northern part ; from what we know of the same depart- 

 ments of the Fauna of Manchuria, tropical forms do not seem 

 to extend northwards in the same way in continental Asia.
