Length of body 3.00-3.50 



Length of head with rostrum 1.71-1.74 



Leng-th of head without rostrum 1.25—1.28 



Width of head 1.00-1.03 



Width of pronotum 0.56-0.59 



Locality. — Luzon, Balintauac, near Manila, August 6, 1916. 



Remarks. — In my previous paper I identified the present 

 species with Eutermes hospitalis Haviland. However, after close 

 examination of a vast number of specimens I have recently come 

 to the conclusion that it is reasonable to separate the two. There 

 are two forms of worker in Eutermes luzonensis, instead of one 

 as in the other, and the soldier's head is much smaller.
