108 THE ENTOMOLOGIST. 



creamy flat scales with the black ones, which latter only occurred in 

 the type. 



The pleurae have some flat white scales which could not be seen 

 in the type, owing to its being somewhat damaged. 



All other characters agree with the specimen from the Pibor. 



Ficalbia inornata, no v. sp. 



Thorax and abdomen uniform deep brown ; proboscis moderately 

 long, deep brown ; pleuraa pale brown. Legs uniform brown. The 

 whole insect with bronzy reflections in bright light. 



? . Head brown, with dull flat scales and paler upright forked 

 scales ; clypeus pale ; proboscis uniform in colour, brown in some 

 lights, violet in others, swollen apically where it is testaceous ; 

 antennae brown ; basal segment pale. 



Thorax deep brown, with traces of a paler line in the middle and 

 in front at the edges, clothed with scanty narrow-curved bronzy 

 scales and long black backwardly-projecting chsetse, especially poste- 

 riorly and over the roots of the wings ; pleurte pale brown with some 

 grey reflections ; scutellum with small flat brown scales showing 

 violet reflections, forming a large mass on the mid lobe, small areas 

 on the lateral lobes, mid lobe with two long median border-bristles, 

 then two shorter ones and a few still smaller ; metanotum nude, deep 

 brown. Abdomen brown, unhanded, with metallic violet and traces 

 of green reflections ; pale ventrally. 



Legs uniform brown, with bronzy and violet metallic reflections, 

 paler basally ; ungues small, equal and simple ; wings with typical 

 brown Ficalbian scales, a somewhat dense patch of them above the 

 cross-veins ; outer costal border spinose and dark ; subcostal vein- 

 scales dark, also the single-rowed median vein-scales, lateral ones 

 pale ; fork-cells of nearly equal length, the first submarginal slightly 

 the narrower, its base slightly nearer the apex of the wing, its stem 

 not quite twice the length of the cell ; stem of the second posterior 

 cell about one and a third the length of the cell ; posterior cross-vein 

 wider than the mid, a little more than its own length distant from 

 it ; halteres with pale stem and fuscous knob. Length 3 mm. 



<? . Head with flat, rather loose violet-brown scales, some show- 

 ing an ochreous tinge ; upright forked-scales dark, showing ochreous 

 reflections in some lights, especially behind ; apparently a single 

 large curved median black chaeta projecting forwards between the 

 eyes ; antennae plumose, dark brown, basal segment pale ; palpi very 

 short ; proboscis dark. 



Thorax as in female, but two median bare lines, very distinct. 

 Abdomen as in female, but with traces of indistinct pale basal lateral 

 spots on the three more basal segments. Fore and mid ungues 

 unequal and simple ; hind equal and simple. 



Wings very similar to the female, but the fork-cells relatively 

 shorter. Length 3 mm. 



Habitat. Transvaal (Mr. Simpson). 



Observations. — Described from a perfect female and two 

 males. 



This is the first female recorded, the three previously known
