long; inner cross-vein (0.23 mm. long) is considerably shorter than 

 distance between both cross-veins and is much more oblique than the 

 0.54-mm.-long, convex outer cross-vein. Anal cell and its 0.23-mm. 

 apical process 0.73 mm. long, the whole anal cell being 3.2 times as 

 long as the apical process. 



Preabdomen covered with brownish appressed hau-s, subshining and 

 bicolored in the specimen examined ; basal tergites (first to third) and 

 lateral margins of fourth and fifth tergites ochraceous yellow, apical 

 part black; 1.25 mm. long and 0.9 mm. wide; third and fourth tergites 

 shortest; fifth tergite shorter (0.25 mm.) than sixth (0.32 mm.). 

 Sternites and major part of membrane ochraceous yellow, only apical 

 part of membrane black. 



Sheath of ovipositor flattened, 0.70 mm. long, at base 0.68, at apex 

 0.29 mm. wide, basally 0.14 mm. high; nearly as wide at base as long; 

 dark brown with yellowish tinge, except below on both sides of apical
