Note .—Dr. Bancroft says of this species: “ This is the 
common Anopheline or Spear Mosquito, plentiful all the year 
round in Southern Queensland, in forest as well as in scrub 
country and even coming into houses. It will bite at any time, 
and possibly is the mosquito associated with malarial fever, in 
Southern Queensland at any rate. The eggs are laid singly, and 
the larvae float horizontally on the surface of the water. They 
live in salt water as well as in running fresh and stagnant 
waters ; they are found about habitations in small collections of 
water also, but not commonly. The larvae present many 
different appearances, some being quite black, others brown with 
white spots. 
This mosquito will live in confinement for about a month if 
fed on dates and will oviposit whilst caged. 
The mosquitoes hatched from larvae, that have been starved, 
are very small in size, and it is a question whether they are not 
what Skuse, and after him Theobald, regarded as Nyssorhynchus 
masteri. Theobald, in his description of N. masteri , from small 
specimens from Queensland, makes these observations : ‘ Mery 
like and closely related to N. annulipes , but the female can 
easily be told by the proboscis being paler at the tip. It is also 
smaller in size, and Skuse says that the sub-costal transverse 
vein is placed considerably beyond the middle of the auxiliary 
vein, whilst in N. annulipes it is situated in the middle.’ These 
characters I find will not hold in Queensland specimens.”
