A brief consideration of the geographical dictclnion of 
these species yields a few interesting considerations ; 
though on the other hand one must put but little trust. in 
the actual figures given, owing to our lack of any thing like 
complete knowledge about the Cicadidae of this region. 
~The numerous and productive islands of the Malay 
Archipelago must certainly produce many more species as 
soon as larger collections are made, and localities more 
systematically worked ; and thus the relative numbers here 
quoted perhaps will be altered a good deal, though the 
general conclusions will probably hold good. 
The total number of species recorded from Borneo in 
this paper amounts to 71, representing 23 genera. Out of 
this total, 28 species are at present confined to Borneo; 
though here again, one must expect to find the distribution 
of many of these species prove to be considerably wider. 
To facilitate a quick comprehension of the geographical 
distributed of the remaining 43 species, I have appended 
a list of them in tabular form. 
It will at once be seen that the majority are well dis- 
tributed over Malaya; and that the largest number of 
species are to be found in the Malay Peninsula (23) ; while 
Java and Sumatra come next with 19 each. Of these 
species four are peculiar to Borneo and the Peninsula, two 
to Borneo and Java, and two to Borneo and Sumatra;
