FRUIT FLIES OF GENUS TOMOPLAGIA — ACZEL 407 



Preabdomen 2.5 mm. long and 2.2 mm. wide, shining, testaceous 

 to brownish yellow, with broad ochraceous yellow hind margins, and 

 covered with pale yellow and black appressed hairs; fifth tergite 0.66 

 mm. long, 1.75 times as long as fourth; lateral and hind margin of 

 fifth tergite with rather closely spaced marginal bristles, strong and 

 black; each of third to fifth tergites with a pair of lateral black spots, 

 which are on third tergite rounded, on fourth oval, and on fifth 

 long-triangular. 



The small epandrium is testaceous yellow (see fig. 3. of Dr. A. da 

 Costa Lima, 1934, p. 119). 



The Argentine specimen was reared from sweet orange by Kenneth 

 J. Hayward, according to information received from Dr. Hayward. 

 After finishing this paper the writer received a small lot of Argentine 

 Tomoplagia from the private collection of Dr. Everard E. Blanchard 

 (Buenos Aires), and among them was a female specimen of trivittata. 

 The author wishes to acknowledge this generous assistance. The 

 description of this specimen with the same wing pattern as figured 

 by Lima (in which much of the intensive yellow of the wing 

 pattern of the Sao Paulo specimen is substituted by brown) is as 

 follows: 



Female: Length 4.5 mm.; wing 4.1 mm. long and 1.7 mm. wide, 

 2,4 times as long as wide. 



Head 0.89 mm. long, 1.36 mm. wide and 1.16 mm. high, colored as 

 in the Sao Paulo male, but the two testaceous yeUow vittae on frons 

 nearly parallel. Frons at vertex 0.68 and at anterior margin 0.52 

 mm. wide, and in median line 0.59 mm. long. Postpedicel 0.29 mm. 

 long and 0.19 mm. wide, 1.6 times as long as wide. 



Cephalic bristles as in the Sao Paulo specimen but anterior upper 

 orbital bristles (ors) slightly shorter than the two pairs of lower 

 orbitals (ori), and posterior ors slightly shorter than anterior ori; the 

 more divergent ocellar bristles as long as the outer verticals. 



Thorax 1.6 mm. long and 1.4 mm. wide, ground color, vittae of 

 mesonotum, and bristles as in the Sao Paulo specimen, but apical 

 pair of scutellar bristles slightly convergent, and the black markings 

 brown. 



Coxae and legs as in the Sao Paulo specimen. 



Halteres brownish yellow. 



Wings with the typical pattern of this species (pi. 1, fig. 3 of Costa 

 Lima, 1934); first costal section 0.59, second 1.45, third 0.73 and 

 fourth 0.50 mm. long; first section of fourth longitudinal vein 1.41, 

 penultimate 0.30, and ultimate 1.01 mm. long; inner cross-vein 0.29, 

 outer, 0.66 mm, long; anal cell 0.85 mm. long, together with the 0.36- 

 mm,-long apical process; apical process slightly shorter than in the 

 Sao Paulo specimen (whole anal cell 2,3 times as long as apical process).
