FRUIT FLIES OF GENUS TOMOPLAGIA — ACZEL 391 



notopleural bristle shorter and weaker than anterior. Dorsocentral 

 pair placed close to transverse suture, approximately in anterior fourth 

 of distance between suture and supra-alar bristles (sa); slightly more 

 widely spaced than prescutellars (prsc=acr) which stands in posterior 

 third of distance between sa and upper postalar bristles. Apical pair 

 of scutellar bristles convergent and sometimes crossing, slightly shorter 

 than basal pair. 



Coxae and legs entirely testaceous yellow. 



Wings with the general pattern of the genus. Tip of humeral cross- 

 vein brownish black. Basal band abbreviated and ending in a diffuse 

 small brown cloud at tip of apical process of anal cell. Subcostal cell 

 (stigma) 2.5 to 2.8 times as long as basally broad. Fhst section of 

 costa (stigma) 0.60, second 1.43, third 0.82, and fourth 0.57 mm. long. 

 Basal section of fourth longitudinal vein 1.32, penultimate (median) 

 0.41, and ultimate 1.36 mm. long. Inner cross-vein 0.32 mm. long 

 and slightly more obliquely placed than the 0.59-mm.-long outer one. 

 Whole anal cell 0.93 mm. long, 2.6 times as long as apical process 

 (0.36 mm.). 



Haltera ochraceous yellow. 



Preabdomen 1.6 mm. long and 1.6 mm. wide, subshining testaceous 

 yellow, covered with appressed brownish yellow hairs. Third to fifth 

 tergites each with a pair of large rounded black spots, larger than in 

 reimoseri; the pau's on third and fourth tergites nearly equal, widely 

 spaced but pair on fifth tergite less so and reaching posterior margin. 

 Fifth tergite (0.54 mm.) 1.7 times as long as fourth (0.32 mm.). 



Postabdomen testaceous yellow; epandrium oval with apex hidden 

 beneath fifth sternite. Membrane mostly black, sternites mostly 

 testaceous yellow. 



Female: Lilve male. Length of body (without ovipositor) 4.6 

 (4.9) mm.; wing 4.5 (4.6) mm. long and 2.1 (2.0) mm. broad, 2.1 

 (2.3) times as long as broad. 



Head 0.85 (0.82) mm. long, 1.41 (1.48) mm. wide, and 1.25 (1.30) 

 mm. high. Frons at vertex 0.66 (0.70) and at anterior margin 0.48 

 (0.50) mm. long, and on median line 0.53 (0.54) mm. long. Postpedicel 

 0.25 (0.25) mm. long and 0.17 (0.16) mm. wide, 1.4 (1.5) times as long 

 as wide. Eyes in profile 0.91 (1.00) mm. high and 0.61 (0.57) mm, 

 wide, 1.5 (1.7) times as high as wide. Genae below eyes 0.13 (0.13), 

 inferior region of postcranium in profile 0.16 (0.17) mm, wide. 



Thorax with scutellum 1.9 (2.1) mm. long and 1.5 (1.6) mm. wide, 

 with the same dusted pattern, black spots, etc. as in male. 



Wings like those of male. First costal section 0.68 (0.73) second 

 1.43 (1.45), third 0.82 (0.86), and fourth 0.59 (0.61) mm. long. Basal 

 section of fourth longitudinal vein (Mi) 1.04 (1.20), penultimate 0.41 

 (0.41), and ultimate 1.34 (1.38) mm. long. Inner cross-vein (to) 0.32 

 (0.34) and outer cross-vein 0.63 (0.63) mm. long, ta always slightly
