FRUIT FLIES OF GENUS TOMOPLAGIA — ACZEL 409 



Pleura throughout shining, with only two dark brown to brownish 

 black spots: above hind coxa a small spot on metapleura, and a 

 larger one on inferior half of ventral pleurotergite, extending in form 

 of a nearly linear process over inferior margin of dorsal pleiu-otergite. 

 Scutellum shining, pale testaceous yellow with some scattered minute 

 hairs on the sides. Postscutellum and mediotergite shining, intensive 

 testaceous yellow, postscutellum with a pair of small lateral black spots. 



Coxae and legs entirely testaceous yellow. 



Wings with the general pattern of the genus, but slightly modified, 

 since apex of apical band is prolonged into tip of first posterior cell, 

 with its wide apex ending at second third of fourth costal section, 

 which therefore has only the posterior third hyaline. Second basal 

 cell mostly hyaline and basal band greatly abbreviated. Subcostal 

 cell (stigma) long, approximately 3 times as long as wide at base. 

 First costal section 0.63, second 1.11, third 0.59, and fourth 0.50 mm. 

 long. Basal section of the fourth longitudinal vein (Mi) 1.16, median 

 0.23, and ultimate 1.11 mm. long. Inner (to) and outer (tp) cross- 

 veins nearly parallel and only slightly oblique, ta 0.23 and tp 0.50 mm. 

 long; ta as long as median section of Mi. Whole anal cell 0.50 mm. 

 long, 4.5 times as long as the short apical process (0.11 mm.). 



Thoracic bristles brownish yeUow; only upper mesopleural bristle 

 present ; posterior notopleural bristle shghtly shorter and weaker than 

 anterior. Dorsocentral pair inserted in anterior fifth of distance 

 between transverse suture and supra-alar bristles (so), and slightly 

 wider spaced than prescutellar pair, which stands near level of sa pair. 

 Apical pair of scutellar bristles convergent and crossed, much weaker 

 than basal pair. 



Halteres testaceous yellow. 



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

 yellow (in the specimen examined it is irregularly darkened) and cov- 

 ered with dark brown appressed hairs. Second to fourth tergites each 

 marked with a pair of rounded black lateral spots, pair on second 

 tergite very small, nearly pointlike, pairs on third and fourth tergites 

 large; fifth tergite with two pah's of lateral black spots, anterior pair 

 large and oval, posterior pair represented by small, round dots touching 

 posterior margin. The 0.50-mm.-long fifth tergite 1.7 times as long 

 as the fourth (0.29 mm.) 



Postabdomen shining, testaceous yellow; epandrium oval with nor- 

 mally shaped surstyli and with well developed shining black anterior 

 gonapophyses ; posterior pair very reduced.
