This species is recorded, and also known to the writer, from other 

 regions of East Africa, not contiguous with our faunal district, north- 

 ward to Abyssinia ; but it is not yet known from tropical West Africa. 



. Occiput and labium light ochreous yellow. Labruni shining 

 black. Ante- and postclypeus dark brown to almost black ; genae 

 dull olivaceous. Frons and vertex black ; frons whitish pruinose 

 anteriorly to base of antennae and anterior ocellus. Very small, 

 almost circular, dull greenish postocular spots. Prothorax black, 

 somewhat lighter at the sides, rather densely whitish pruinose. 

 Thoracic dorsum black, a narrow line on median suture and a broad 

 ante-humeral band pruinose blue ; the latter about half the breadth 

 of each mesepisternum, touching laterally the humeral suture. Sides 

 rather densely pruinose, but the pattern still recognisable ; black 

 from humeral suture to half-way to metastigma, also a line in dorsal 

 end of first (obliterated) and a rather broad band on full length of 

 second lateral suture. Ventral surface ochreous with sutures lined 

 with black to almost black, whitish pruiuose. Legs black, external 

 side of tarsi and claws reddish brown, femora pruinose. 



Dorsum of abdomen black, pruiuose blue, the pruinosity ending at 

 narrow black terminal rings of segments 3-7 ; sides dull reddish 

 brown. Appendages (Text-fig. 25) dull reddish brown, tips of superior 

 blackish. The most characteristic feature is the long inferior branch, 

 beginning with a rather sharp angle, and the absence of a sub-basal 

 median tooth. A* at Cnq or very slightly proximal ; pterostigma 

 dark brown to almost black, comparatively large, its costal distal 

 angle very acute. 



9 . Black and light olivaceous, sometimes with a more yellowish 

 tinge, the black markings much reduced. Labrum only dark at base, 

 but this colour not deep black ; anteclypeus olivaceous, postclypeus 

 obscure anteriorly ; frons olivaceous to base of antennae and anterior 

 ocellus.
