A Monograph of Culicidae. 
Ungues of the female equal and simple. Wing scales thin or 
moderately broad, symmetrical. 
Six species of this genus have been received from the West 
Indies, South America, India, and Malay Peninsula. Dr. Lutz 
speaks of them as “Wood Mosquitoes,” and says they all haunt 
damp woods near the river or seashore, where the “ bromelias ” are 
abundant, and always contain water. Most of them are likely to 
breed in “ bromelias,” some only do so. These “ wood mosquitoes ” 
have a peculiar habit of, so to speak, staying in the air with the 
last pair of legs thrown over the back, and, with their thin body 
and long legs, looking very much like spiders. They will attack 
man and dogs in the daytime. The pale parts of their legs shine 
distinctly in the sun while they are staying in the air. 
The character by which I have separated these species from 
Aedes is the presence of bristles on the metanotum, seen in no 
other members of the family Culicidae except Sabethes and 
Trichoprosopon. These chaetae, when denuded, leave a distinct 
scar where they were attached. 
The larvae are, according to Dr. Lutz, of Culex type, but are 
usually coloured red, green, or blue. 
The species W. Grayii, from St. Lucia, is a solitary species 
occurring up to 1000 feet above sea-level in the forests, and 
W. pertinans occurs high up as well, and in woods and forests.*

* The species described here as Wyeomyias very closely resemble 
% Sabethes, but the wing scales are never asymmetrical as in that genus.
