Geographical Distribution of Culicidae. 79 
South Africa. Aedes are limited in number ; the few" species that 
do occur are found in Europe, North America, Africa, and one 
probably in the West Indies. The genera closely related to 
Aedes, namely Uranotaenia, Arribalzaga, Aedeomyia, mihi, and 
Haemagogus, Williston, are. found in the following countries : 
Uranotaenia in North and South America, Africa, West Indies, 
Australia, and New Zealand; Aedeomyia in India, Australia, 
and South America; Haemagogus is at present only recorded 
from the West Indies. 
Of Corethra we know little, but the genus seems to be widely 
distributed, species having been recorded from North and South 
America, from Manila, India and Europe. 
Mocldonyx is confined, as far as our present knowledge goes, 
to Europe. 
Owing to mosquitoes being closely united to man and his 
habitations, it is not surprising that we find many species with a 
wide distribution. Amongst the latter may be mentioned Culex 
(now Stegomyia) fasciatus , Fabricius, which has been described 
under such a variety of names. This is certainly one of the 
commonest mosquitoes and one of the most annoying. Its dis¬ 
tribution is best seen by examining the map (p. 292), the districts 
where it has been recorded and sent from being darkened ; the 
probability is that much of the intervening spaces still uncoloured 
will have to be filled in as more collections arrive. 
It has so far been sent in numbers from South America 
(where it is known as G. mosquito), from Central America and 
the neighbouring West Indies ;• it occurs in the Southern States 
of North America, both on the East and West coasts of Africa, 
as well as North Africa (Port Said); in India, both north and 
south, it is abundant, while in Malay its numbers are very 
great; in Siam, as well as along the coast right through the 
East Indies, it may be constantly found ; away north through 
China, Formosa, and Japan it is to be observed in more or less 
abundance, whilst I trace the C. Bancroftii of Skuse from 
Australia to be no other than this widely distributed species. 
In Europe it certainly occurs in Italy under the name of 
C. elegans (Ficalbi), in Portugal and Spain under the name of 
C. calopus (Meigen) ; it is doubtfully recorded under the name 
G. calopus in England, and I have received specimens from Malta 
and Gibraltar. With the species closely allied to our common 
English mosquito Culex pipiens, Linn., namely Culex fatigans, 
Wied., we find much the same. A glance at the map (Fig. 183)
