are known to me. The distribution of Christmas Island Moths 

 seems to show very cleariy that it has no connection with the- 

 Malayan siih-regiou, but is very intimately related to the Ceylonese 

 sub-region, with a less strong relationship to the Australasian fauna 

 found in Queensland, Kew Guinea, and the Pacific groups. In the 

 collection hardly any of the numerous species confined to the Malayan 

 sub-region occur ; and Avhere there are closely allied species in the 

 Ceylonese and Malayan faiinas, it is the species of the former region 

 that occur in Christmas Island, not of the latter, and this holds with 

 regard to large conspicuous species Avhose distribution is well known, 

 and not only small and obscure species which might be supposed to- 

 have been overlooked in the Malayan sub-region.
