Genus Wyeomyict. 
Halteres with ochraceous stems, with a ]ine of black scales up 
one side and black scales round the knob. 
Length .—3 • 5 to 4 mm. 
Habitat .—Rio de Janeiro (Dr. Lutz, 4. 7. 1899). 
Observations .—Described from more or less damaged speci¬ 
mens sent by Dr. Lutz. This species can be readily identified, 
however, by the extremely long proboscis, and is thus easily 
separated from W. Grayii; the metathoracic bristles are also in 
a group of four, instead of in a straight line, as in IF. pertinans. 
Dr. Lutz calls it the “ Wood Mosquito.” 
Although the specimens are rather damaged, one can detect 
basal white lateral spots on the abdomen clearly in the best 
specimen. Its long rostrum is very marked, and should make 
its identity an easy matter. 
5. Wyeomyia Trinidadensis. n. sp. 
Thorax deep brown, with bronzy scales. Abdomen black, 
with metallic green reflections, basal white lateral spots, which 
often pass into basal bands, venter white scaled. Legs long, 
black, the mid tarsi white above. Ungues small, equal, simple. 
Proboscis as long or longer than the whole insect.

violet and sometimes green reflections, sides with rather grey 
scales; around the eyes are short black bristles projecting over

project from the head between them; antennae rather short, 
black, basal joints with a grey sheen, almost white in some 
lights; palpi very short, covered with purplish-brown scales ; 
clypeus brown, with grey sheen; proboscis thin, very long, as 
long or longer than the whole insect, deep brown with metallic 
reflections. 
Thorax deep brown, with flat spindle-shaped bronzy-green 
scales, which appear deep bronzy in some lights ; numerous deep 
brown and golden-brown bristles over the roots of the wings ; 
prothoracic lobes covered with flab scales, showing blue, violet 
and ochraceous reflections, and a few forwardly projecting 
bristles; scutellum densely clothed with flat bronzy scales, 
black when denuded; mid lobe with four border-bristles, the 
two median ones crossing one another; metanotum nearly black, 
with apparently three bristles in a row behind and two in front ;
