naked eye. The differences, which I found in the copula- 
tory-apparatus of these two species, which however are 
very related to one another, will be cleared up by the 
accompanying figures. 
The two species are to be separated also by their 
pattern, but there are specimens in which this will be 
rather difficult. 
How it is with D. choaspes Btlr. from Celebes and 
with D. limniace is still a question to me, because our 
material is as yet insufficient. 
It is I suppose well known, that D. limniace Cr. has 
not yet been found in Sumatra and the islands West of it.
