 m-cu very pale; distal section of Cu\ lonp:, sinuous, in the specimen 

 figured with a short branch before apex; cell Mi relatively narrow 

 at margin, subequal to Cu; vein Ut A distinct, the cell a little wider 

 on basal half. Most of the specimens lack the apical branch on the 

 distal section of Cux and its occurrence must be held as adventitious. 

 Abdomen pale, densely clothed with long setae, very dense at end 

 of organ, rendering it difficult to separate the two sexes. Male 

 hypopygium (fig. 2) with the basistyle (6) relatively stout, the outer 

 face on basal two-thirds with numerous large setigerous punctures,
