vol. 3, p. 426, 1915. , 
A very small black mosquito. Mesonotum dark brown, legs black- 
ish, abdomen with or without basal segmental whitish bands, lateral 
spots present. Very uncharacteristic in markings, but distinct on 
the characters of larvae and male genitalia. 
The larvae live in permanent water with aquatic vegetation. They 
have the habit of hanging themselves up on leaves, etc., by the hooks 
of the air tube, or often lie on the bottom, seldom coming to the sur- 
face. No observations are on record of the biting habits. The spe- 
cies is rare and insufficiently studied in its habits. 
Distribution —Cuba and southern States.
