 brown spot at apex of apical process. Stigma approximately 2.6 times 

 as long as broad at base. First costal section 0.64, second 1.45, third 

 1.00, and fourth 0.54 mm. long. Basal section of the fourth longitu- 

 dinal vein 1.11, penultimate 0.41, and ultimate 1.50 mm. long. The

 Basal section of fourth longitudinal vein 1.17 (1.17), penultimate 

 (median) 0.39 (0.38), and ultimate 1.57 (1.55) mm. long. Inner 

 cross-vein 0.32 (0.33), outer cross-vein 0.61 (0.66) mm. long. Anal

Preabdomen 1.6 (1.6) mm. long and 1.5 (1.5) mm. wide. Third 

 to sixth tergites each with a pair of lateral black spots, which are sub- 

 equal (the pair on the sixth tergite is shghtly larger) and oval in shape.

Ovipositor sheath shining testaceous yellow, with dark brown 

 apical margin and covered with fine dark brown hairs; it is dorso- 

 ventrally flattened in the specimens examined (basally only 0.11
