ing their galleries in the sides of the termitaria of T. lacteus. 

 Their galleries are very irregular but strongly built and of a pale 

 chocolate-brown colour, but appear to have no regular structure 

 or distinct nest. The soldiers ai'e generally numerous; and when 

 their retreat is cut off they turn round, snapping their slender jaws 

 together with a distinct click; both they and the workers — which 

 are very light-coloured — seem to dislike the light, rushing off 

 under ground as soon as the nest is opened. Winged specimens 

 were found on the 3rd of February" in a nest under some stones 

 about 18 miles from Sydney. 



Hah. — Thornleigh, near Sydney (W. W. Froggatt).
