Genus Uranotaenia.

and Malayi, milii, must also be included in this genus, anyhow 
provisionally, until more material comes to hand, because of the 
squamate structure of the head and scutellum and the wing 
venation. 
At present the distribution of the genus is as follows : South 
America, North America, Australia, New Zealand, India (?), 
Malay Peninsula (?), and West and Central Africa. 
All that is known of the life-history of this genus comes from 
Dr. Lutz, who writes me that the larvae are like Anopheles , but 
lie slightly obliquely in the water. They are often brilliantly 
coloured, red, blue and green, and have a short respiratory tube. 
The adults sting generally in the daytime, but do not seem 
inclined to do so, and may be found in the grass near places 
where they breed.
