A Monograph of Culicidae. 
This genus includes several Gulices which present quite a 
different appearance to all the others, save a few of the banded 
proboscis group of Calex, such as Cidex taeniorhynchus. They are 
stoutly built insects, mostly black and white in colour, with 
usually banded legs and banded abdomen. The flat head scales 
give them a very different appearance to Cidex, whilst the flat 
scutellar scales will separate the females from other Culices with 
flat scaled heads, such as Aedes, Deinocerites, &c. The genus 
includes the world-wide Cidex fasciaius, and the closely related 
C. scutellaris. The larvae (Fig. 16) of certain species of this genus

have been roughly described and figured by some correspondents, 
and seem to breed in very similar places to Cidex. The adults 
are in most cases very vicious biters, both by day and night in 
some cases. One of the members of this genus, C. fasciaius, is 
being experimented with in Cuba by the American Commission 
on Yellow Fever, and is the agent by which the germs of this 
disease are spread. The genus is represented in most tropical 
and sub-tropical countries, and one species ( C . fasciatus) occurs 
in the warmer parts of South Europe. 
The eggs of S. fasciata are laid separately, not in “ rafts ” 
as in Cidex.
