482 A Monograph of Culicidae. 



lines, a paler curved one on each side in front of the roots of the 

 wings, two median darker ones which converge posteriorly (the 

 effect being quite different under the microscope to under a 

 hand-lens), chaetae over the roots of the wings brown ; the scales 

 are paler in front of the scutellum, which is also clothed with 

 narrow-curved pale scales and with eight posterior border- 

 bristles to the mid lobe ; metanotum bright brown ; 

 pleurae pale silvery grey. 



Abdomen shiny black, clothed with deep brown scales 



with dull violet black reflections, each segment with a 



basal median creamy-yellow spot, basal segment all dark 



and the last two with almost complete basal bands, hairs 



brown. Genitalia with large claspers very broad at 



the base becoming finer apically with a lateral apical 



expanding segment ; lateral process of basal lobe with 



three large spines, the two largest with fine bent tips, the 



third acuminate, a leaf -like plate and then a smaller spine. 



Legs deep brown ; the hind pair with apex of tibiae, 



first, second and third tarsals very narrowly pale 



banded, the pale scales to some extent involving both 



sides of the joints, traces of this banding seen in fore 



' legs and still less on the mid ; fore and mid ungues 



/ unequal, both uniserrate, the smaller with a tooth close 



/ to base ; hind equal and simple. 



Wings with rather dense moderately large lateral 

 scales, especially on the branches of first fork-cell ; first 

 imu. 216, fork-cell longer and narrower than the second posterior 

 a o¥ P cell, its base a little nearer the base of the wing, its stem 

 <!nn"'\ahi about one-third the length of the cell ; stem of the second 

 posterior nearly two- thirds the length of the cell ; super- 

 numerary and mid-cross veins united, both bending in towards the 

 base of the wing, the posterior cross-vein about twice as long as 

 fche mid about one and a half times its own length distant from 

 it ; halteres with dusky pallid stem, fche knob dark inside. 

 Length. — 6 mm. 



Habitat —Stanley Town, New Amsterdam (Dr. Rowland). 

 Time of capture. — July. 



Observations. — Described from a single perfect male. 

 It is somewhat obscure, but the hairy banded proboscis will at 

 once separate it from the species of Culex which it resembles and 

 places it in the genus Trichopronomyia. 



It differs from T. annulata in not having a banded abdomen,
