72 SYKPIIIDJE. 



and below, an oblique band running to the superior and inferior 

 corners of the eyes; proboscis black; antennae short, black, brownish 

 towards the base ; third joint oval ; arista long, yellowish, feathered 

 with long hairs. Thorax black, covered with dense and short 

 reddish hairs ; the ground-colour is deep black behind the suture 

 and grey in front of it, and consequently the thorax viewed from 

 behind appears to be banded; pleurae grey pollinose, the hairs 

 becoming paler below. Scutellum brown, clothed with hairs like 

 those on the main portion of the dorsmn of the thorax, reddish 

 tomentose on the hind border and below. Squamulae blackish, 

 Avith a dark fringe ; halteres dirty yellow. Abdomen entirely 

 blackish brown, somewhat dark reddish on the sides of the second 

 and on the fourth segment ; the bullae are black, disposed as in 

 In Hig era, the largest and most prominent bulla being that on the 

 second segment ; the latter also exhibits a basal band of short 

 yellowish hairs, which is broader towards the sides; hairs on the 

 following segments more golden. Venter black. Legs black, the 

 tibiae whitish at the base, those of the hind pair more narrowly ; 

 hair short and dense, mainly black on the upper side of femora and 

 yellow on the tibiae, which are brown in the case of the two anterior 

 pairs ; hind tibiae broad, on the inside with a black, on the outside 

 with a yellow fringe ; all the tarsi red. those of the first pair very 

 short and broad. Wings appearing rather dark on account of the 

 short and dense pubescence, which covers all the surface from the 

 fore border to the line formed by the subapical. postical cross-vein 

 and seventh vein ; the hind border is therefore narrowly hyaline, 

 but in the axillary cell there is a broad spot of pubescence ; alula 

 also pubescent ; the extreme base of the wings is blackened ; there 

 is also a broad dark median band running from the stigma to the 

 end of the second basal cell ; this band is darker towards the small 

 cross-vein ; kink in the third vein deep, angular, with only the 

 rudiment of an appendix ; lower angle of the discal cell with a 

 long appendix. 



Type $ , a single specimen from the Uganda Protectorate. Daro or 

 Durro Forest, Toro, 4,000-4,500 ft., 25-29. x. 1911 (8. A. Neave). 

 There is also an aberrant female from Obuasi, Ashanti, W. Africa, 

 2. vii. 1907, " caught on flower " (Dr. W. M. Graham), which I 

 regard as a melanic form of the present species. The hairs on 

 head, thorax, and scutellum are grey, not fulvous ; the abdomen is 

 entirely shining black, even at the base and distal extremity, and 

 the hair, including the lateral fringe, clothing it is grey, not 

 golden ; the fore tibiae are black instead of brown, and the fringe 

 on the hind tibi'-e is black on the outer as well as on the inner side. 

 The eyes seem to be without distinct bands. Wings with the 

 same pattern and pubescence as in the type, but the pubescence is 

 less developed, partly wanting in the anal cell and entirely wanting 

 in the axillary cell ; the glabrous hind border is therefore broader ; 

 the appendix to the kink in the third vein is rather long.
