GERALD F. HILL, 



The trunk, which was hollow, was sealed up on top with earth. When a portion 

 of the wood was cut away, the interior was found to be nearly filled with earthy 

 material, pierced by a few galleries, which contained the castes found in the mound. 

 Four months later (15.1.1920) Coptotermes (:)lacteus, Frogg., was found in possession 

 of the trunk and had commenced to build a typical termitarium on the site formerly 

 occupied by the small mound referred to above. H. eucalypti was found under the 

 casing on the bark and in tunnels in the adjacent soil ; in the latter were 

 also three winged adults. It appeared that the invading Coptotermes were the 

 survivors from a large termitarium 6 ft. distant, which had been destroyed on 

 18th August 1919.

On 25th November 1920, at Magnetic Island, near Townsville, the trunk of a large 

 bloodwood tree [Eucalyptus) was found to have its sunn}^ side almost encased in 

 an earthy crust, under which were found many workers and a few soldiers of this 

 species. Nearer the ground a few adult winged forms were found. Arising from the 

 sandy soil near the trunk and within a space of a few feet were about a dozen vertical 

 tubes (fig. 26), ranging from 5-23 cm. in height by about 1-3 cm. in diameter, which 

 communicated each with an irregular chamber about 25 cm. long by H cm. wide.
