When Meyrick described this genus he had before him two species, both 

 represented by single examples. Hampson (Proc. Zool. Soc. 

 Lond., 1899, p. 232) cited as type of the genus E. asyphela 

 Meyrick, Tonga. Since then two species have been described, E. 

 polytima Turner (Trans. Roy. Soc. S. Austral., xxxii, p. 96, 1908), 

 and E. argyresthalis Hampson (Ann. Mag. Nat. Hist. (8), xii, p. 1, 

 1913), both represented by single examples. These two differ con- 

 siderably in appearance from the two species described by Meyrick, 

 and I am not sure that they really belong here, but there is not 

 sufficient material to enable me to make a thorough investigation. 



However, I now have the opportunity of examining eight 

 specimens from Samoa, and I had expected to find E. asyphela* 

 represented among these. On the contrary, I have discovered, 

 in spite of the scantiness of the material, three new species. Of each species 

 there is a pair, and, in addition, two females in poor condition apparently 

 belonging to E. asynopta. I hope that the publication of these 

 descriptions and figures will induce entomologists living in Samoa, 

 Tonga and Fiji to collect these small moths in large numbers. 

 A hundred of each would not be too many, and there is little 

 doubt that there are more species awaiting discovery.
