Hah. — Mackay, Queensland (Mr. Gilbert Turner). 



JNIr. Turner says : " These white ants were obtained from a 

 nest about a foot in diameter, and six inches above the surface 

 of the ground." But no particulars were given of the internal 

 structure. 



The soldiers differ from l)oth E. fumipennis and E. fumigahis 

 in the bright ferruginous colour of the head, and are intermediate 

 in size between the two. The winged form is darker-coloured, 

 and larger.
