//«?;.— Hall's Creek, Kimberley, W.A. (Mr. W. O. Mansbridge). 



Mr. Mansbridge says : — " These termites were taken from the 

 heart of a gum-tree some 20 feet from the ground, and had com- 

 pletely eaten the centre out of the tree, only a mere shell remain- 

 ing; most of the trees in this district are eaten out in the same 

 manner by this species." 



The soldiers are ver\' like those of 7'. hidciiti, our common Sydney 

 species, but the winged forms are very distinct from any other 

 species I have examined. The thick costal and subcostal nervures 

 and the curiously granulated wings are veiy characteristic.
