 cloud at apex of apical process of anal cell. Tip of humeral cross-vein 

 brownish black. Subcostal cell (stigma) approximately 2.8 (2.9) 

 times as long as basally broad. First section of costa 0.70 (0.75), 

 second 1.59 (1.75), third 0.95 (0.85), and fourth 0.61 (0.59) m.m. long. 

 Basal section of fourth longitudinal vein 1.27 (1.34), penultimate 

 (between both cross-veins) 0.29 (0.32), and ultimate 1.85 (1.66) mm, 

 long. Inner cross-vein 0.36 (0.36) mm. long and slightly more oblique 

 than outer cross-vein (0.68 (0.73) mm. long). Anal cell with apical 

 process 0.93 (1.13) mm. long, 2.0 (2.6) times as long as apical process

Preabdomen 2.2 (2.9) mm. long and 2.0 (2,2) mm. wide, faintly 

 shining testaceous yellow in ground color, covered with dark brown, 

 golden shining hairs. In all male specimens examined only the fifth 

 tergite is marked with a pair of lateral brownish black spots, which 

 are variable in size, usually very small, and in one specimen represented 

 by pointlike yellowish brown dots; very probably they may be wholly 

 absent. The fifth tergite (0.59 (0.82) mm.) is 1.5 (1.7) times as long 

 as fourth (0.34 (0.56) mm.); intrasclerital membrane and sternites 

 testaceous yellow, 



Postabdomen testaceous yellow, relatively small; epandrium wide- 

 oval, nearly round with normally shaped surstyli. Gonapophyses 

 shining black, posterior pair very reduced.

 (6.3) mm. long and 1.9 (2.6) mm. broad, 2.6 (2.4) times as long as 

 broad.

 mm. high. Frons at vertex 0.80 (1.18) and at anterior margin 0.57 

 (0.68) mm. broad, and in median line 0.68 (1.00) mm. long. Post- 

 pedicel 0,34 (0.34) mm. long and 0.22 (0.25) mm. wide, approximately 

 1.4 (1.5) times as long as wide. Eyes in profile 1,13 (1.43) mm. high

 section of fourth vein 1.27 (1.59), median or penultimate 0.31 (0.32), 

 ultimate 1.48 (1.77) mm. long. Inner cross-vein 0.36 (0,50), outer 

 cross-vein 0,63 (0.86) mm. long. Anal cell together with apical
