of dull creamy scales, so dull that they are only noticeable in 

 certain lights ; apical segments with a few scattered creamy 

 scales ; border-bristles dull golden. 



Legs uniformly brown, except the under side of femora, 

 which are pale ; in certain lights the legs show ochreous reflections. 

 Wings with brown scales and with a nude shiny white basal 

 patch, lateral scales on the apical portions of the veins and on 

 the major area of the second and on one side of the fourth 

 elongate, clavate, those on the basal parts of the second and 

 fourth longer than the others ; median vein-scales short and 

 spatulate, a single row only, those on the sixth somewhat longer 

 than the rest ; first sub-marginal cell about the same length and 

 scarcely narrower than the second posterior cell, its base nearer 

 the apex of the wing, its stem longer than the cell ; stem of the 

 second posterior about the length of the cell ; supernumerary 

 cross-vein slightly nearer the base of the wing than the mid 

 cross-vein ; posterior cross-vein longer than the mid and about 

 its own length distant from it ; halteres with grey stem and 

 black scaled knob. 

 Length. — 2 mm. 



$ . Proboscis brown, swollen from a little past the middle 

 ventrally, apex truncated, labellae leaf-like and acuminate, clothed 

 with small brown scales. Palpi very thin and needle-like, about 

 two-thirds the length of the proboscis, swollen at the base and 

 clothed with small brown scales. Antennae densely plumose, 

 plume-hairs brown. 



Legs brown, unhanded ; fore and mid ungues simple, unequal ; 

 hind, small, equal and simple. Wings with similar scales to the 

 female, but the lateral clavate ones rather shorter and broader ; 

 the upper branch of the first sub-marginal cell rather close to 

 the first long vein; first sub-marginal cell scarcely narrower 

 but almost the same length as the second posterior cell, its stem 

 as long as, or longer than the cell, its base nearer the apex 

 of the wing than that of the second posterior cell, stem of the 

 latter as long as the cell ; posterior cross-vein longer than the 

 mid and about its own length distant from it, supernumerary 

 and mid cross- veins united. Upper costal border with black 

 spines. 



Length. — 2 mm. 



Habitat. — Lado (female) ; Bahr-El-Jebel (male) (Dr. A. 

 Balfour) ; Congo Free State (Drs. Dutton and Todd).
