FRUIT FLIES OF GENUS TOMOPLAGIA — ^ACZEL 357 



black markings are very characteristic for this species. Third and 

 fourth tergites each with three black spots, one median and two 

 laterals extremely variable in size; the lateral spots situated near 

 lateral margin of tergites, and median spot always reaches anterior 

 margin; in one specimen fourth tergite is mostly black, the three 

 black spots being separated only by two linear vittae. Fifth tergite 

 with a pair of rounded subtriangular large black spots separated by a 

 testaceous yellow narrow median vitta. Fifth tergite 1.8 (1.7) times 

 as long (0.45 (0.59) mm.) as the fourth (0.25 (0.34) mm.). Inter- 

 sclerital membrane and sternite testaceous yellow, with or without 

 black parts. 



Postabdomen testaceous yellow; epandrium oval with normally 

 shaped surstyli and with two pairs of shining black gonapophyses 

 subequal in length but anterior pair much thicker than posterior. 



Female: Like male. Body 4.1 (4.2) mm. long; wings 3.9 (3.9) mm. 

 long and 1.6 (1.6) mm. broad, 2.4 times as long as broad. 



Head 0.80 (0.80) mm. long, 1.32 (1.36) mm. wide, and 1.04 (1.11) 

 mm. high. Frons at vertex 0.59 (0.57) and at anterior margin 0.45 

 (0.43) mm. wide, and in the median line 0.59 (0.54) mm. long. Post- 

 pedicel 0.20 (0.21) mm. long and 0.18 (0.19) mm. wide, only 1.1 times 

 as long as wide. Eyes in profile 0.86 (0.73) mm. high and 0.52 (0.57) 

 mm. wide, 1.6 (1.3) times as high as wide. Genae below eyes 0.08 

 (0.09) and inferior part of postcranium in profile 0.13 (0.13) mm. wide. 



Thorax with scutellum 1.7 (1.8) mm. long and 1.4 (1.4) mm. wide, 

 with the same characters as in male. 



Wings like those of male. First costal section 0.57 (0.50), second 

 1.11 (1.09), third 0.75 (0.73), and fourth 0.50 (0.45) mm. long. Basal 

 section of the fourth vein 0.98 (0.88), penultimate 0.29 — 0.35, and 

 ultimate 1.29 (1.20) mm. long. Inner cross-vein 0.27 (0.25), outer 

 0.53 (0.50) mm. long. Anal cell with apical process 0.68 (0.68) mm. 

 long, the whole cell 3.2 (3.4) times as long as entire apical process (0.18 

 (0.20) mm.). 



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

 fifth tergites each with three black spots, which are variable in size 

 and shape ; lateral spots are near lateral margin and usually long-oval 

 in shape, median spots may be as large as, or considerably larger than, 

 lateral spots, in shape transverse-oval to rhomboid. On sixth tergite 

 a pau* of lateral black spots, less widely spaced than those on anterior 

 tergites, sometimes a small triangular median spot present, reaching 

 anterior margin of the tergite. In some specimens the median black 

 spots form an almost uninterrupted vitta. Sixth tergite (0.29 (0.38) 

 mm.) slightly longer than fifth (0.25 (0.27) mm.). 



Sheath of ovipositor usually dorsoventrally flattened (at base only 

 0.14 (0.16) mm. high) and entirely shining testaceous yellow, covered 

 with appressed fine brownish yellow hairs; it is 0.52 (0.61) mm. long,
