October 27th. 12 larva hatched during the previous night and 
one after 12 hours immersion. 
October 28th. Larvee began moulting. 
October 3oth. All completed first moult. 
November 4th. Larvee pupated. 
November 7th. First imago (a male) hatched. 
November 8th. A male and female hatched. 
The breeding jar was kept at a temperature of 23° C. It was thus 
seen in this case that eggs, which had remained dormant for 
from 45 to 47 days, incubated. 
Those I hatched had remained dormant for a longer period. 
How long this period of rest can remain when the eggs are desic- 
cated we cannot at present say, but sufficient has been shown to 
prove that eggs laid in a small collection of water on a ship which 
may suddenly dry up, may remain dormant for at least two 
months, and this alone would enable the species to be carried 
great distances in dried-up tanks of old sailing ships, much further 
now by rapid ocean transit 
The larve. 
The larval form of Stegomyia fasciata can at once be told from 
that of its common campanion (Culex fatigans WIEDEMANN). 
In fact it has no general resemblance to a typical Culex, and the 
behaviour is quite different. The Stegomyias pass most of their 
time at the bottom of the water and slowly come to the surface to 
take air, and then go down again. Their colour also differs, being 
greyish white, whilst in Culex the colour is generally some shade 
of brown. Nevertheless they come to the surface to breathe, and 
so are as easily killed by paraffin as other Culicines. 
Time of appearance of the adults. 
The period over which this Gnat extends varies. For instance in 
Brisbane we learn from BANCROFT (1908) that it is present and 
bites throughout the year. In the Philippine Islands, according to 
LUDLOW (1908), « in places where the rainy season begins in
