Habitat. —Bupengary, S. Queensland (Bancroft) (5. 12. 99) : 
Hexham Swamp, near Newcastle and Richmond, N.S.W., Mt. 
Kembla, Illawarra, N.S.W. (Skuse and Hamilton) ; Natal 
(Walker). 
Time of appearance .—In Queensland in April, September, 
October, and November (Bancroft); Illawara, X.S.W., January 
(Hamilton). 
Observations.- —Westwood’s type of C. alternans is in the Hope 
Collection, Oxford ; I have carefully examined it, and find it to 
be the same as Walker’s C. commovens and Skuse’s C. hispidosus. 
The remnant of Walker’s type is in the British Museum 
collection. A good series of specimens has been sent by Dr. 
Bancroft from Queensland. 
This large mosquito is a day-flying species found in the bush. 
It is known in Queensland as the Scotch Grey and in New South 
Wales as the Hexham Grey. A second consignment from Dr. 
Bancroft were bred from larvae in sea water, with sp. g. 1025, 
and also from fresh water. It is subject to considerable variation 
in colour.
