2S L. de l^iceYiWe— Butterflies of the subgenus Tronga. [No. 1,' 



geographically separated, as they overlap the typical form at certain 

 points. The Ceylonese species can be satisfactorily separated from the 

 continental form ; the species from Hainan I have not seen.

From the list given above it will be seen that it is only in Indo- 

 China that more than one species of Isamia is found. I. grotei, male 

 only, described from " Cochin" (Cochin China being evidently meant, 

 not the district of that name in South India) is probably tlie same as 

 J. margarita, Butler; I. marseuU is probably the same species; but 

 Lfabricii belongs to quite another group (i.e., to the chloe group), being 

 entirely unglossed with blue on the upperside, which is a conspicuous 

 feature in the other three species. Unfortunately I do not possess a 

 single specimen of Isamia from any part of Indo-China, so am unable to 

 speak about them from first-hand knowledge.
