174 A Monograph of Culicidae. 



three tarsals broader than on the other feet ; fore and mid ungues 

 equal, uniserrated, the hind equal and simple. 



Wings with brown scales, fork-cells short, upper border 

 darker than the rest of the wing ; first sub-marginal longer and 

 slightly narrower than the second posterior cell, its stem nearly 

 as long as the cell, stem of the second posterior cell as long as 

 the cell ; posterior cross-vein some distance from the mid cross- 

 vein. Lateral vein-scales rather long. Halteres with pale stem 

 and fuscous knob. 



Length. — 4 mm. 



Habitat. — Peradeniya, Ceylon. (E. E. Green), 



Time of capture. — January (1902). 



Observations. — Described from a single ? . 



It differs from all known Stegomyias that have a banded 

 proboscis in its thoracic ornamentation. The mid tarsi look all 

 dull white in some lights ; this is due, I fancy, to the ventral 

 surface of the segments being pale-scaled. The thorax is slightly 

 rubbed, but is evidently entirely covered with pale scales which 

 now and again present the same rusty hue as that seen in the 

 head scales.

 abdomen blackish with basal white dagger-shaped median 

 patches ; fore legs brown with a white spot on base of first

 white spot on basal half of tibia, base of first tarsal broadly 

 white, and the other segments with basal white bands. 



9 . Head black mostly covered with large flat snow white 

 scales, with a dark patch on each side, and black bristles project-
