ground pools in other localities. If a visit be made 
when the whole area of the Two-Mile Scrub is dry, or 
after prolonged wet weather has converted it into an 
extensive swamp, neither larvae nor adults of these 
species may be found. 
Dunwich was the first locality from which males 
and larvae of Anopheles atratipes were known, being 
collected by Mackerras in 1926.* He designated a Dun- 
wich male the allotype of this species. It is a black 
anopbeline. with a conspicuous white patch on the 
fringe at the tip of its wing. The freshwater sedge and 
tea-tree swamps between the sandhills and the bay. and 
peaty depressions along their margins are typical breed- 
ing places of A. atratipes, Uranotaenia pygmea (also 
found in the Brown Lake), Culex postspicaculosus and 
Culex sp. near cylindricus, though larvae are often widely 
scattered and difficult to find. Anopheles stigmaticus. 
which also breeds here, is, on the mainland, most com- 
monly found in shaded creeks and rocky mountain pools. 
Of these. A. atratipes an C. sp. near cylindricus will bite 
man, the latter being, both as larva and adult, probably 
the commonest species encountered in the Dunwich area. 
In the deep clear pools of the heath flats, such as 
that behind the pumping station, A. atratipes and Theo- 
baldia sp. near atra breed. This is the only species of 
Theobaldia known from Queensland and is of interest 
in that its closest relative, Theobaldia atra , is known only 
from Perth. Western Australia. 
Along the edge of the bay-side swamps and in the 
Two-Mile Scrub two small species of Aedes with spotted 
wings are vicious biters. These are Aedes kochi, a com- 
mon pest species in New Guinea, which at Dunwich has 
been found breeding in the water-holding leaf-axils of 
Pandanus and Crinum, and Aedes qahnicola, which is 
known only from the coastal areas of Moreton Bay, and 
in other localities has been found breeding in saw-grass 
( Gahnia ). During the summer, one of the commonest 
biting species in the area, in swamp, scrub, heath and 
open forest is Taeniorhynchus linealis, the larva and 
male of which have never been discovered. Larvae and 
pupae of this genus attach their breathing-tubes to the 
roots of aquatic plants from which they obtain their 
oxygen without the necessity of rising to the surface of
