the whole foot is shiny creamy white ; in the hind legs the greater 

 part of the femora are white, the apex only dark and the white basal 

 bands on the metatarsi and first three tarsi 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 knot. 



Length 4 mm. 



Habitat : Peradeniya, Ceylon. 



Time of capture : January, (1902).

 rusty hue as that seen in the head scales.

 brown, the fore and mid metatarsi and first tarsals with small white apical
