FRUIT FLIES OF GENUS TOMOPLAGIA — ACZEL 361 



lateral black spots, in this species relatively large; a black dot behind 

 wing base. Pleura shining, except for the whitish pruinose meso- 

 pleuron (anepisternite) and sternopleuron (katepisternite), with three 

 black markings — a broad horizontal black vitta crossing sternopleuron 

 and broader than the yellow vitta above it on upper margin, a large 

 black spot above hind coxa, and on inferior part of pleurotergites a 

 double one, very broad, on ventral pleurotergite (occupying lower two- 

 thirds) and much narrower on dorsal, Scutellum shining pale ochra- 

 ceous yellow with some short black hairs on sides; middle third of 

 postscutellum pale testaceous yellow, lateral thirds black. Medio- 

 tergite entirely shining, intensive, testaceous yellow. 



Thoracic bristles brownish yellow and somewhat flattened; two 

 mesopleural bristles present on both sides, but inferior very weak 

 and shorter than half of superior bristle. Posterior notopleural 

 bristle two-thirds as long as anterior but much weaker. Dorsocentral 

 pair inserted in anterior tbird of distance between transverse suture 

 and supra-alar bristle, spaced slightly wider than prescutellar pair, 

 which stands in posterior third of distance between upper postalar 

 and supra-alar bristle. Apical pair of scutellar bristles distinctly 

 shorter than basal pair and convergent. 



Coxae and legs entirely testaceous yellow. 



Wings with the general pattern of the genus ; apical half of humeral 

 cross-vein brownish black on upper surface of wing; costa slightly 

 darkened only at tip of subcosta; basal band very abbreviated, ending 

 in an indistinct brownish cloud. Subcostal cell (stigma) approxi- 

 mately 2.4 times as long as basally broad. First costal section (stigma) 

 0.63, second 1.29, third 0.75, and fourth 0.59 mm. long. Basal 

 section of the fourth longitudinal vein 1.09, penultimate (or median) 

 0.45, and ultimate 1.23 mm. long. Inner cross-vein 0.34 mm. long 

 and more obliquely situated than the 0.59-mm. outer cross-vein. 

 Anal cell 0.85 mm. long, including apical process (0.38 mm. long) ; 

 the whole ceU is approximately 2.2 times as long as the apical process 

 itself, 



Halteres entirely testaceous yellow. 



Preabdomen 1.3 mm. long and 1.2 mm. wide, shining testaceous 

 yellow, covered with appressed short black hairs; second to sixth 

 tergites each with a pair of lateral black spots; black spots on second 

 tergite small, on other tergites large, all slightly transverse-oval in 

 shape except for rounded spots on the 0.34-mm. sixth tergite. The 

 0.27-mm. fifth tergite is slightly shorter than sixth. 



Ovipositor sheath shining testaceous yellow, covered with appressed 

 minute black hairs, apical margin with pair of small brown lateral 

 dots Sheath considerably shorter (0.52 mm.) than basally broad 

 (0.77 mm.) and dorsoventrally strongly flattened; at apex 0.36 mm, 

 wide and at base only 0,16 mm, high in profile. Apical part of ovi-
