FRUIT FLIES OF GENUS TOMOPLAGIA — ACZEL 359 



anterior pair of recurved upper orbital bristles. Genal bristle short 

 but distinct by the brownish black color. 



Thorax with scutellum 2.0 mm. long and 1.5 mm. wide, testaceous 

 yellow in ground color; mesonotum covered with silky whitish pruinos- 

 ity and with appressed thickish pale yellow hairs, except for posterior 

 margin which is shining; in the dusting there are no vittae present. 

 The usual pair of oval black spots relatively large, each situated 

 between prescutellar and upper postalar bristles; a minute black dot 

 behind and beneath wing base. Pleura shining, only inferior part of 

 sternopleuron (katepisternite) sparsely dusted with whitish pruinosity ; 

 they are marked with thi'ee black spots as in reimoseri but the double 

 one on inferior part of dorsal pleurotergite is as wide as on ventral. 

 Scutellum shining testaceous yellow with some minute yellowish hairs 

 at sides. Median part of postscutellum yellow, whitish dusted; 

 lateral parts black, which continues in a pair of large lateral long- 

 oval black spots on the shining yellowish red mediotergite. 



Thoracic bristles brownish yellow and somewhat flattened; inferior 

 mesopleural bristle but slightly shorter than superior; posterior 

 notopleural bristle slightly shorter than anterior; dorsocentral pair 

 inserted approximately in, or slightly before, anterior thh-d of distance 

 between transverse suture and supra-alar bristle, spaced slightly 

 farther apart than prescutellar pair, which stands approximately in 

 posterior fourth of distance between upper postalar and supra-alar 

 bristles. Apical pair of scutellar bristles almost parallel and slightly 

 shorter than basal pair. 



Coxae and legs entirely testaceous yellow, without special characters. 



Wings with the usual pattern of the genus; tip of humeral cross-vein 

 brownish black; costa blackened at tip of humeral cross-vein and at 

 tip of subcosta. Basal band abbreviated and terminated in a small 

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

 cell (stigma) 2.9 times as long as basally broad. First section of costa 

 0.63, second 1.25, third 0.80, and fourth 0.63 mm. long; basal section 

 of fourth longitudinal vein 1.02 penultimate 0.38, and ultimate 1.36 

 mm. long. Inner cross-vein 0.30 mm. long and almost parallel to 

 outer cross-vein (0.61 mm.). Anal cell with 0.34-mm. apical process 

 0.85 mm. long, the whole cell exactly 2.5 times as long as the entire 

 apical process. 



Halteres testaceous yellow with brownish knob. 



Preabdomen 1.7 mm. long and 1.6 mm. wide, ground color sub- 

 shining testaceous yellow, covered with appressed brownish yellow 

 hairs. Third to sixth tergite each with pan of lateral black spots; 

 black spots of third to fifth tergites small, rounded or long-oval, and 

 placed in two parallel longitudinal rows, unusually near lateral margins 

 of corresponding tergites; black spots on sixth tergite larger and con- 

 siderably closer placed than anterior pairs. Sixth tergite slightly
