showers in April, and it is distinctly rainy in June, S. calopus 
apparently appears in June or July, increases greatly in numbers 
and is most noticeable in July, August, September and October, 
and then gradually diminishes again ». 
In Cuba it is specially troublesome in the rainy season, where, 
according to DESVOIDY, it was called « Mosquito » by the natives. 
From different parts of the world it has been sent me every 
month of the year. In some places it always seems to occur, in 
others a certain seasonal prevalence occurs, but at present this has 
not been satisfactorily worked out. 
Pairing of Stegomvia fasciata. 
From general observations it seems a single male may fertilize 
many females. Dr. ST. GEORGE GRAY found in St. Lucia that the 
males fly from one female to another, apparently never tiring. 
The method of copulation, as first pointed out by GRAY, and later 
admirably figured by GOELDI (1902), is for the male to get under 
the female, who may or may not carry him off and complete the 
process in the air. 
Breeding places of Stegomyia fasciata. 
There is no doubt that, with a few notable exceptions, this insect 
is a purely domesticated Gnat. With the exception of one being 
found in the scrub of South Queensland by Dr. BANCROFT, and 
one or two other casual notes sent me, the general consensus of 
opinion and observation show that the Yellow Fever Mosquito is 
a companion of man. 
BANCROFT, writing in his work on the Mosquitoes of Queensland 
(1908), however, says : « It is an introduced species and never goes 
wild ». The single specimen sent me from the scrub was evidently 
exceptional. 
NEWSTEAD (1907) records the following breeding places in the 
Congo region : « Adults were hatched from larva and pupa taken 
from water collected in old pots and tins and from a foul smelling 
pool used for steeping manioc ».
