Genus Danielsia. 245 



cell ; posterior cross- vein about twice its own length distant from 

 the mid ; lateral vein scales long and straight. 



Halteres creamy. 



Length. — 4 mm. 



Habitat. — Bihe, Angola (Dr. Creighton Wellman). 



Observations. — Described from a perfect female. A very 

 distinct species, easily told by the thoracic and abdominal 

 ornamentation and leg banding. It clearly comes in this genus, 

 but the scutellar scales are rather broader than in the type 

 (Danielsia albotaeniata. Theobald).

 bands. Fork-cells of wings short. Male palpi brown, nearly as 

 long as the proboscis.
