process (0.95 (1.00) mm.) slightly longer than rest of cell, and con- 

 siderably longer than petiole {Cih-{-An2); the whole anal cell only 1.8 

 times as long as the apical process, 



Preabdomen subshining pale ochraceous to testaceous yellow, cov- 

 ered with pale yellowish and brownish hairs, 2.6 (3.0) mm. long and 

 on the second tergite 1.8 (2.1) mm. wide; fom-th and fifth tergites each 

 with a pair of vittalike lateral black marks, and third tergite with a 

 pair of lateral small dots, black to pale brown. Fifth tergite 0.81 

 (0.91) mm. long, 1.7 times as long as fom-th. Sternites, membrane, 

 and postabdomen of same color as tergites. 



Epandrium oval; two pairs of gonapophyses ("claspers" of authors) 

 shining black, posterior pair smaller.

 mm. wide, and 1.86 (1.93) mm. high. Frons at vertex 0.88 (0.95) and 

 at anterior margin 0.G3 (0.68) mm. wide, and in median line 0.80 

 (0.93) mm. long. Postpedicel 0.48 (0.50) mm. long and 0.23 (0.23)

 penultimate 0.57 (0.63), and ultimate 2.43 (2.61) mm. long; inner 

 cross-vein (ta) 0.57 (0.70), outer 1.62 (1.29) mm. long; anal cell 1.86 

 (1.86) mm. long, including apical process (1.02 (1.02) mm.), apical 

 process is longer than half the whole cell length. 



Preabdomen 2.2 (3.0) mm. long and 2.4 (2.6) mm. wide with the 

 same black markings as in male but sixth tergite without black 

 marks; fifth tergite 0.32 (0.43), sixth 0.43 (0.61) nam. long, longer 

 than the fifth. 



Sheath of ovipositor 1.29 (1.45) mm. Jong, in some specimens dor- 

 soventrally flattened (first numbers), in others subcylindrical, shining 

 and translucent testaceous yellow, evenly covered with fine golden 

 shining brownish hairs; more than twice as wide at base (1.20 (1.11) 

 mm.) as at apex (0.52 (0.45) mm.), slightly longer than basally wide. 

 Apical part of ovipositor (ovipositor of Benjamin) dorsoventrally
