FRUIT FLIES OF GENUS TOMOPLAGIA — ACZEL 339 



Wings with the same modified wing pattern as in incompleta; sub- 

 apical band completely absent, except for brown spot on tip of fourth 

 longitudinal vein. A small hyaline dot at apex of second longitudinal 

 vein. Apical half of humeral cross-vein brownish black. Basal band 

 abbreviated and terminated in a subtriangular translucent brown 

 spot at tip of apical process of anal cell. Anterior half of second basal 

 cell hyaline. Fourth longitudinal vein (Mi) densely and very distinctly 

 setulose on upper surface of wing almost to tip of vein; lower surface 

 very loosely setulose between base and inner cross-vein. Subcostal 

 cell (stigma) 3 times as long as broad at base. First section of costa 

 0.66, second 1.25, third 0.68, and fourth 0.50 mm. long. Basal 

 section of Mi 1.11, penultimate 0.25, and ultimate 1.16 mm. long. 

 Inner cross-vein 0.33 mm. long and nearly parallel to outer cross-vein 

 (0.53 mm.). Anal cell, including apical process, 3 times as long 

 (0.77 mm.) as apical process itself. 



Halteres yellow. Legs testaceous yellow, without special armature. 



Preabdomen 1.9 mm. long and 1.5 mm. wide, shining dark testa- 

 ceous yellow, covered with appressed brownish black hairs and marked 

 with four pairs of lateral black spots, one each on second to fifth 

 tergites; spots on third and fourth tergites rounded, spots on second 

 tergite narrow, long, transversely placed, and spots on fifth tergite 

 long-oval in shape. Fifth tergite approximately 1.4 times as long 

 (0.57 mm.) as fourth (0.41 mm.). 



Postabdomen testaceous yellow; epandrium very wide-oval, with 

 normally ^shaped surstyli and with two pairs of shining black gona- 

 pophyses, posterior pair shorter and more acute than anterior.

 Cainzo, near Tafi Viejo, November 18, 1950, R. Golbach. 



Tomoplagia brevipalpis, new species 



FiGUBES 91; 97, e; Plate 19, figure 2 



This rather large species belongs to the conjuncta group and may be 

 distinguished from the related species by the characters of the wing 

 and by the black markings of the abdomen. 



Male: Length 5.6 mm.; wing 5.6 mm. long and 2.5 mm. wide, 2.2 

 times as long as wide. 



Head 1.07 mm. long, 1.75 mm. wide, and 1.59 mm. high, ochraceous 

 yellow, mesofacial plate, lunula, and lower half of the occiput paler 

 in color; frons at vertex 0.93, at anterior margin 0.68 mm. wide, and 

 in median line 0.75 mm. long, considerably shorter than wide at 

 vertex. Frontal vitta bare and slightly darker than genovertical, 

 parafacial, and ocellar plates, except for a wedge-shaped area in front 

 of ocellar plate. Mesofacial plate impressed, oral margin raised and
