 line in front of venation, a narrow, wavy line not far from 

 the apex of the infuscation (both transverse), a longitudinal, 

 narrow line not very far from caudal margin of the wing, its 

 middle about opposite the apex of venation and a subquadrate 

 area against apex of the submarginal vein, hyaline. Scutellum 

 more coarsely scaly than the scutum, large, with a pair of setae 

 at its apex. Frons prominent, moderately narrow, the face 

 greatly inflexed. Club obliquely truncate, longer than the 

 funicle and as broad, the funicle joints annular, the first dis- 

 tinctly narrower than the others. Pedicel wider than long, 

 crescentic. Third tooth of mandible more obtuse than the 

 other two. Hind tibial spurs double. Marginal vein somewhat
