and the V-shaped face cinereous, third antennal joint blackish, bluntly conical, less than twice aslong as wide and one-fourth 
as long as the dark arista; palpi oval, twice as long as wide, no long apical seta. Posterior dorsocentral moderate, apical 
scutellars approximate. Third abdominal tergite and its flattened setula brown, pygidium large and very long, tipped with 
two long strong black bristles. Legs simple, the hind metatarsi as long as the subsequent joints and two-thirds as long as 
their tibiae which have two strong extensor setzte. Wings hyaline, veins yellowish, a strong seta at base of costa, costal 
sections proportioned 1 : 0 5: 1 : 0.4, first posterior cell gradually widening, sections of fourth vein ri : 1.2 : 3.5, of fifth
