XI. —One New Genus and some New Species of 
Cassidae from Borneo, with a List of all the 
Species at present known from that Island.— 
By Dr. Franz Spaeth, Vienna. 
The descriptions of new species in this paper are 
drawn up chiefly from material sent to me from the 
Sarawak Museum during the last few years. The 
opportunity has been taken at the same time to list all 
the species of this Family at present known from Borneo, 
and, at my request, Mr. J. C. Moulton, Curator of the 
Sarawak Museum, has kindly added the data of the 
specimens of Cassidae under his care. 
In point of numbers this list is not so extensive as 
that of the Bornean Hispidae recently published by Dr. 
Gestro, in which 59 different species are recorded from 
Borneo, and there is little doubt that further collections 
from this interesting country will provide further 
additions to our list of Cassidae.
