1138 REVISION OF AUSTRALIAN LEPIDOPTERA, 



other the Larentiadae^ which rapidly became a dominant type in 

 Asia and Europe and spread thence over all the world, making 

 their way also to Australia at a later period ; here they have 

 flourished as elsewhere, but the Dichromodes group found itself 

 already so well established and adapted to its situation, that it 

 has apparently not suffered much from their competition, though 

 not strong enough to retaliate by invading the enemy's country, 

 except that it has contrived to settle a very small colony in the 

 mountains of New Zealand. I think this is a clear and interesting 

 case. 



In the following tabulation of genera I have included not only 

 the Australian genera, but all those from other regions with which 

 I am acquainted by actual observations, as it will help to give an 

 idea of the range of the family, which has been hitherto unrecog- 

 nised. Brephos, for example, has been usually classed with the 

 Noctuina (though Lederer showed that it could not remain there 

 and constituted a separate family for it), and the others have been 

 distributed at random in various groups. The Australian genera 

 are numbered in succession ; the others are distinguished by letters 

 attached to the number of the genus immediately preceding them, 

 which serve to show their position in sequence.
