We estimate that over 100 species will be found to occur in 

 Australia. The group resolves itself into fourteen genera, 

 Telesto, Bd., and Trapezites, Hiib., being the most predominant 

 and widely distributed. Perhaps it is as well to mention that 

 the drawing up of the generic characters and identifications 

 has been made by Mr. Meyrick. The descriptive and other 

 work in connection with the paper has been performed by the 

 junior author. The specific descriptions may appear unneces- 

 sarily lengthened, but the abortive works of many of the 

 older authors, which for the purpose of study are useless, dis- 

 poses of this objection. We may state that we shall at all 

 times be pleased to identify any specimens entrusted to us, 

 and wish to thank the many kind friends for assistance, especi- 

 ally Messrs. Illidge, Waterhouse, Turner, Tepper, and Lyell. 



Those genera asterisked (*) are confined to the Australian 

 region. 



In conclusion perhaps it is well to mention Euschenion 

 Raffl,€sicE, Mac. This insect is undoubtedly not referable to 

 the Hesperiadse. It has a large and well developed frenulum, 

 which is invariably absent in the HesperiadcE and in all other 

 Butterflies. Superficially it recalls the Agaristidoe. In neura 

 tion, however, it nearly approaches the Hesperiadce. It 

 stands by itself as a separate family, and must, we think, be 

 regarded as related to the ancestral form of the Hesperiadce, 

 intermediate between them and the Thyrididce.
