 islands of the Malayan Archipelago. 



Subfamily II. BRACHYRHYNCHIN^. 



The short rostrum is the principal characteristic of this sub- 

 family, which includes by far the largest number of the genera 

 and species of Aradida). In the species of some genera a sulcation 

 of the sternum is found, but this is not combined with a long 

 rostrum, and the divisional character is maintained. 



Stal has divided the subfamily into two divisions, but as only 

 one is found in this fauna, they need not be considered here.
