Mr. E. Meyrick on 



the (Ecophwidx. I am not acquainted with any larva of 

 the genus, but have received the cocoon of /. machinoodii 

 from Ceylon, and it is surrounded by au open network, as 

 in Plutclla itself and some other genera of the family. 



Together with Imtna I have described two curious new 

 genera, which, whilst possessing peculiar types of neuration, 

 are more allied to Imma than to anything else known at 

 present. 



The mutual affinities of the individual species are ex- 

 tremely puzzling; when closely compared no two are alike 

 in structure, and species which resemble one another in 

 one apparently important structural point usually differ in 

 several others, so that it is hard to know on which to rely. 

 Hence I can only offer a tentative arrangement of the 

 species, which may be modified by subsequent further 

 knowledge.
