168 A. A. Girault: 
present, not margined by sulei; cephalic and caudal margins of 
the metathorax guarded by a carinated suleus, divided more or 
less irregularly by short longitudinal carinae. 
Wings densely ciliate, the marginal cilia very short, the caudal 
ones of the caudal wings more dense and somewhat longer than 
the same cilia of the fore wing; marginal vein over a fourth longer 
than the submarginal which is about twice the length of the stigmal 
vein. The latter is short but with a distinct neck. 
Antennae as in the preceding species. Pedicel slightly longer 
than first funicle joint, which is subquadrate; funicle joints 
widening distad, the last distinetly wider than long. Flagellum 
regularly clavate.
