distad except the club joint which is shorter than the preceding joint 

 b}' about a third. Joints 2 to 10 subequal, longest, a third longer than 

 the proximal joint, the scape subequal to them or slightly longer. 

 Club joint and proximal funicle joint subequal. Pedicel globular, 

 somewhat longer than wide. Lateral ocelli not touching the eye mar- 

 gins. Posterior wings hyaline but tip tinged with some brownish ; no 

 discal cilia, excepting a double row along the edge of the caudal mar- 

 gin and a single row along the cephalic margin ; also some brownish 

 just out from the marginal vein over the whole blade. Marginal cilia 

 of posterior margin not more than twice the width of the wing blade 

 which is not linear but acuminate and slightly curved. Whole of the 

 blade of cephalic wing clouded, excepting the clear portion proximad 

 of the end of the marginal vein and a less regular, less clear area just 

 distad of a distinctly deeper band across the wing just at the end of 

 the marginal vein (or stigmal vein). Marginal cilia moderately short, 

 the longest only a fourth the greatest wing width. Discal ciliation 

 uniform, about seventeen longitudinal lines. Marginal vein deflexed 

 into a distinct, true stigmal vein, which is shaped like a snake's head. 

 Discal ciliation not dense enough to obscure cilia. Scutellum not 

 visible. Head behind the eyes longitudinally striate, the striations 

 delicate.
