mm. long and slightly more obliquely placed than the outer cross-vein 

 (0.59 (0.63) mm.). Whole anal cell 0.85 (0.95) mm. long, approxi- 

 mately 2.6 times as long as the apical process (0.32 (0.36) mm.). 



Halteres ochraceous to testaceous yellow. 



Preabdomen 1.6 (1.7) mm. long and 1.2 (1.6) mm. wide, shining 

 testaceous yellow and covered with golden shining appressed brown- 

 ish yellow hairs. Third to fifth tergites each with a pair of lateral 

 black spots, placed in nearly parallel longitudinal rows, only the pair 

 on the third tergite slightly wider spaced than the others; black 

 spots of third tergite usually rounded, those on fifth tergite largest 

 and long-oval but never reaching anterior or posterior margins. Fifth 

 tergite in this species short, only 1.2 (1.3) times as long as fourth 

 (fifth 0.43 (0.45), fourth 0.35 (0.34) mm.). 



Postabdomen testaceous yellow; epandrium wide-oval with nor- 

 mally shaped surstyli and with two pairs of shining black gonapo- 

 physes; posterior pair nearly as long as anterior, but much slender. 



Female: Like male. Length of body 4.2 (4.1) mm.; wing 4.1 

 (4.0) mm. long and 1.9 (2.2) mm. broad, 2.1 (2.2) times as long 

 as broad. 



Head 0.70 (0.71) mm. long, 1.32 (1.58) mm. wide, and 1.07 (1.07) 

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

 0.38 (0.38) mm, broad, and medianly (from lunula to vertex) 0.57 

 (0.54) mm. long. Postpedicel 0.23 (0.22) mm. long and 0.19 (0.16) 

 mm. wide, approximately^ 1.2 (1.3) times as long as wide. Eyes in 

 profile 0.86 (0.91) mm. high and 0.48 (0.46) mm. wide (long), 1.8 

 (2.0) times as high as wide. Genae below eyes 0.07 (0.07) and the 

 inferior region of postcranium in profile 0,18 (0,19) mm. wide. 



Thorax with scutellum 2.0 (1.9) mm. long and 1.5 (1.4) mm. wide, 

 with the same black markings as in male. 



Wings like that of male; first costal section 0.66 (0.59), second 1.38 

 (1.38), third 0.75 (0.77), and fourth 0.50 (0.48) mm. long. Basal 

 section of fourth longitudinal vein (Mi) 1.04 (1.09), median (penul- 

 timate) 0.32 (0.34), and ultimate 1.36 (1.36) mm. long. Inner cross- 

 vein (ta) 0.32 (0.32) mm. long and slightly more obliquely placed 

 than the outer cross-vein (0.63 (0.63) mm. long); ta approximately 

 as long as median section of Mi (between both cross-veins), Wliole 

 anal cell 0.86 (0.84) mm. long, 2.4 (2.2) times as long as the apical 

 process (0.36 (0.38) mm.). 



Preabdomen without ovipositor 1.5 (1.5) mm. long and 1.7 (1.6) 

 nam. wide. Third to fifth tergites each with a pair of lateral black 

 spots, the pair on second tergite slightly wider spaced than the others; 

 all three pairs of rounded spots may be equally large or may be 

 unequal, in the latter case the spots on fifth tergite are largest and 

 those on the third smallest. On sixth tergite a pair of small lateral
