In October, 1910, in examining some nests of Irido/iiyntier iiifldu'< 

 at Glenfield (New South Wales), I saw thousands of specimens of this 

 beetle. In parts of the nests they were clustered so thickly together, 

 that from a space, a square inch in extent, several dozens could have 

 been taken. The ants moved freely about them without in any way 

 interfering with them. The beetle also occurs in nests of Steiiamma 

 lonyircps and of Iridotuyiine r ifnieratis.
