TERMITES FROM THE AUSTRALIAN REGION. 
many workers and a few soldiers and nymphs. 'Ihie latter were in 
the stage preceding the final moult, the antennae then having 15 
joints. Stained specimens showed no indication of the presence of 
o(‘elli. A second colony (soldiers and workers only) was taken in 
the near vicinity on :^6.10.1() in similar circumstances. In both 
instances the ex])osed surfaces of the timber were encased in a thin 
brittle layer of earthy matter under covei' of which considerable 
damage had been done.
