FRUIT FLIES OF GENUS TOMOPLAGIA — ^ACZEL 349 



humeral cross-vein dark brown only on the upper surface of wing; the 

 neighboring part of costa remains yellow. First costal section (stigma) 

 0.61 (0.66), second 1.25, third 0.68, and fourth 0.45 mm. long; first 

 section of the fourth longitudinal vein 1.25, penultimate 0.29, and 

 ultimate 0.98 mm. long; inner cross- vein slightly shorter (0.27 mm.) 

 than the distance between both cross-veins and nearly parallel to the 

 0.50-mm.-long outer cross-vein; both cross- veins placed slightly more 

 obliquely than in monostigma. Anal cell with apical process 0.68 (0.72) 

 mm. long. Process (0.23 (0.25) mm.) about half as long as the rest 

 of the cell; whole anal cell nearly three times as long as apical process, 

 which latter is slightly shorter than in monostigma. 



Preabdomen shining ochraceous yellow, opaque, covered with very 

 short brown hairs, 1.6 (1.7) mm. long and 1.4 (1.2) mm. wide; third 

 and fourth tergifces each with one pair and fifth tergite with two pairs 

 of lateral black spots, all of which are smaller than in female; second 

 tergite in all specimens examined with pair of pointlike lateral black 

 to brown dots; fifth tergite 0.57 (0.52) mm. long, 1.7 (1.8) times as 

 long as fourth. Sternites and membrane ochraceous to whitish yellow, 

 sternites slightly shining. 



Epandrium ochraceous yellow and wide-oval; only one pair of 

 shining black gonapophyses present, posterior pair entirely absent. 



Female: Length 4.0 (3.9) ram.; wing 4.1 (4.1) mm. long and 1.8 

 (1.6) mm. wide, 2.3 (2.5) times as long as wide. Head 0.75 (0.70) mm. 

 long, 1.23 (1.20) mm. wide and 0.95 (0.91) mm. high. Frons at 

 vertex 0.54 (0.52), at anterior margin 0.36 (0.36) mm. wide, and in 

 median line 0.50 (0.48) mm. long. Postpedicel 0.25 (0.25) mm. long 

 and 0.16 (0.16) mm. wide, 1.5 times as long as wide. Thorax, includ- 

 ing scuteUum, 1.6 (1.5) mm. long and 1.3 (1.3) mm. wide, with the 

 same black markings as in the male. 



Wings like those of male; first costal section 0.68 (0.63), second 1.41 

 (1.34), third 0.75 (0.85), and fourth 0.54 (0.52) mm. long; first section 

 of the fourth longitudinal vein 1.45 (1.38), penultimate (between the 

 cross-veins) 0.34 (0.29), and ultimate 1.02 (0.98) mm. long; inner 

 cross-vein 0.27 (0.27), outer 0.59 (0.50) mm. long, inner slightly 

 shorter than distance between both cross- veins; anal cell 0.72 (0.68) 

 mm. long, including the apical process (0.25 (0.23) mm. long); whole 

 anal cell is 2.9 (3) times as long as apical process itself. 



Preabdomen 1.8 (1.7) mm. long and 1.4 (1.4) mm. wide; second to 

 fourth tergites with the same markings as in male, fiith and sixth 

 tergites each with a pair of lateral black spots; these black spots 

 usually larger in female than in male; fifth tergite about as long (0.27 

 (0.27) mm.) as sixth (0.29 (0.27) mm.). 



Sheath of ovipositor in specimens examined slightly flattened dor- 

 soventrally and slightly longer (0.68 (0.73 mm.) than wide at base 

 (0.64 (0.63) mm.) ; at apex 0.27 (0.27) mm. wide and at the base 0.43
