forming regular hair-tufts, a distinct black spine at the apex of 
the ante-penultimate segment ; the apical segment about half the 
length of the penultimate ; plume hairs of antennas deep brown. 
Thorax as in the Abdomen narrow, brown, with either basal 
lateral white spots or basal white bands, which spread out laterally; 
hairy. Basal lobes of the genitalia broad and truncated. Legs 
ornamented as in the $ ; fore and mid ungues unequal, the 
larger uniserrated ; hind equal and simple. 
Length, 4.5 mm. 
This rare and delicate mosquito, I bred from a few larvae 
obtained from a well and also a water cask at Deception Bay ; 
it live>3 well in confinement, and will bite when encouraged ; 
oviposits singly. The larva? are pale in colour, almost white ; 
during one winter I kept some alive and they appeared to give 
birth to young larvae (paedogenesis) on August 26th, 1903 ; 
I tried to verify this observation, but it did not occur in summer ; 
unfortunately, I have not been able to obtain larvae since with 
which to make further observation in winter. One or two of 
these mosquitoes oviposited in an aquarium covered with 
muslin ; in due course young larvae were noticed, and these 
grew to maturity, and were turning into pupae when a number 
of minute larvae were observed ; the question was : — Were these 
minute larvae produced by the other larvae % If they were not, 
they were from eggs, which had not hatched out in the first in- 
stance, and which had lain dormant about two month* . The 
eggs of some mosquitoes, which oviposit singly, easily sink in 
water if touched, and it is reasonable to suppose that the incuba- 
tion period might be affected in consequence. Many more 
observations need to be made to clear up these questions. 
GILESIA. — Theobald (1903). 
Head covered with rather broad flat spindle-shaped scales ; 
mesothorax with scattered flat spindle - shaped scales and 
narrow curved ones ; scutellum with small flat scales and 
some spindle-shaped ones. Palpi four-jointed in the $ , rather 
long, about one-fourth the length of the thick proboscis, apical 
joint long, penutlimate joint swollen, globose, the two basal 
joints small. Basal joint of the antennae with numerous hair- 
like bristles and a few small flat pcales. Ungues very thick, 
rather short and all with a thick blunt tooth. Wing venation 
much as in Culex ; fork-cells short and the veins clothed with 
rather broad elongated scales like Taeniorhynchus. 
Male unknown. 
This genus is related to Culex on the one hand and Stegomyia 
on the other, whilst the wings give it a Taeniorhynchus-like ap- 
pearance. The important characters are the scale ornamentation 
of the head and scutellum and the hairy and scaly basal antennal 
joint and the curious claws and palpi. A single species only is 
known from Queensland.
