This is a smaller species than U. fumiperuiis, with the head 

 of the soldiers much lighter in colour. Though found in similar 

 situations to the former it ne^ er builds nests, simply forming an 

 irregular network of galleries under dead logs, sheets of bark, or 

 stones, and sometimes attacking woodwork and old fences. The 

 queen's cell is frequently broken when turning over a log and the 

 queen and eggs exposed; winged ones were found in two nests 

 under some large stones (at Thornleigh) about 10 miles from 

 S3'dney on November 1st. Mr. Adamson sent me eight supple- 

 mentary queens, together with a number of immature winged 

 ones, taken from a nest at Uralla. I have never found more 

 than a single queen in all the nests I have opened. 



My specimens agree with Brauer's, except that his are slightly 

 smaller. I am greatl}' indebted to the kindness of the Director 

 of the Naturhistorisches Hofmuseum in Wien for co-types of 

 Brauer's species, which he generousl}' presented to me, so that I 

 have been enabled to carefully compare them.
