There have been several attempts (Butler, Hampson, Swinhoe, Tarns) to 

 clear up the identity of the various moths which for convenience I group in the 

 genus Cosmophila. The whole classification of this genus and its associates 

 (Anomis, etc.) requires revision. 



With regard to the subspecific relationships, I do not feel justified in intro- 

 ducing C. erosa Hubner into the auragoides — lyona association, though I propose 

 to go a step further than I did in 1924, and associate together C. auragoides 

 auragoides (Tropical Africa and Madagascar) and C. auragoides lyona (Indo- 

 Australian region). The figures in my 1924 paper show the rather wide diver- 

 gence of C. erosa Hubner from the others.
