minutely pubescent ; apical half of all femora and the whole of 

 the middle tibiae reddish tawny : some whitish-grey hairs below 

 femora; hind tibiae shortly pubescent, with reddish-bronze reflec- 

 tions. Wings pale grey, apical half pale brownish; no distinct 

 stigina, but a rattier broad ill-defined brown baud runs from the 

 stigmatic portion of the costa towai'ds the posterior border, but 

 fades away before reaching it ; discal cell three times as long as 

 broad ; anal cell closed just before the border ; by a strong con- 

 A'ergence of the veins the fourth posterior cell (terinin, O.-S.) is 

 almost closed, thus (if a stable specific character) separating this 

 species from all other Oriental species in this genus; halteres 

 yellowish, knobs black, rather large ; tegula? cinereous grey.
