 described from the Adelaide River, and Palnierston, Northern 

 Territory.

Ann. Mag. Nat. Hist., (8), xvi., p.263(1915). 



The eggmass of this species is very long and narrow, measuring 

 29 mm., by an average of 1 "5 mm., and contains a very large 

 number of eggs, which are a light amber-brown, cylindrical, and 

 pointed like a cigar at the apex, and measure 1"3 x 0'2mm.(vix). 



They were found on a blade of grass overhanging a small, 

 sandy creek in Townsville, just as the Hy had finished laying 

 them. It is a common species at Ching Do and Kuranda.
