This species, originally described from specimens from New South Wales 

 (Uralla), has not been recorded previously from Victoria. 



1 have received six nest series from Victorian collectors, one of which com- 

 prises an ovigerous queen which has been compared with an alate co-type. As- 

 sociated with the queen were seven soldiers, eighteen large larvae, 3 young "second 

 form" royalties and an adult de-alate male Calotermef obscurus Walker. The 

 remaining colonies comprise soldiers, larvae and n>Tnphap. In some colonies the 

 soldiers vary considerably in size, but in each there are some which equal the 

 co-types. The largest colony contains 10 soldiers and 190 larvat' and nymphae.
