up this intention and I restricted it to the monographic 
revision of the Mrcoprera and PrLANIPENNIA, the two orders

of the malayan and papuan archipelago. I describe also 
the species known from those parts of Borneo and New 
Guinea, that do not belong to the dutch possessions, as 
they very probably also will occur in them. Those of neigh- 
bouring countries are noted so far as they are important 
for comparison. 
The materials studied are those of the Leyden Museum 
and some types of Gerstaecker from the Greifswald Museum, 
which Prof. G. W. Miiller generously communicated to me 
and that facilitated this work very much. My best thanks 
for this courtesy, that enabled me to decide many questions 
about the systematic position of little known species. I had 
no time to work out materials of other museums, though I
