FRUIT FLIES OF GENUS TOMOPLAGIA — ACZEL 403 



are three vittae, golden yellow dusted and equally narrow, one 

 in median line and two lateral ones in dorsocentral line; the pale 

 ochraceous yellow dusted space between two golden yellow vittae 

 twice as broad as one vitta. Only one pair of oval black spots, each 

 between upper postalar and prescutellar bristles; a pair of round 

 black spots, each beneath the base of wing and below postalar 

 callosity. This is the only known species with small but very distinct 

 shining brownish black circlets on mesonotum at bases of the presutural, 

 dorsocentral, supra-alar, postalar, prescutellar, and scutellar bristles. 

 In 'punctata only the dorsocentral and prescutellar bristles are inserted 

 on shining dark brown circlets. 



Thoracic bristles long and strong, brownish yellow and somewhat 

 flattened; apical pair of scutellar bristles crossed; two pairs of long 

 mesopleural bristles, inferior slightly shorter than superior; dorso- 

 central pair inserted about half way between transverse suture and 

 supra-alar bristle. 



On pleura only two small black dots present, a round one on sterno- 

 pleura below sternopleural bristle and an oval one on inferior margin 

 of ventral pleurotergite at base of haltere; the latter may be absent, 

 principally in male. Sometimes there is a smaller black or brown dot 

 above hind coxa. Scutellum pale ochraceous yellow, with narrow 

 basal part subshining and with apical two-thirds sparsely covered 

 with yellow appressed hairs. Each side of postscutellum with a 

 triangular black marking. Mediotergite (metanotum of authors) 

 shining and intensively brownish yellow with reddish tinge. 



Coxae and legs entirely ochraceous to testaceous yellow, with 

 bristles and hairs ochraceous yellow except for a row of densely spaced 

 anterodorsal bristles and a row of much weaker posterodorsal bristles, 

 and, between these, two rows of hairs on hind tibiae brownish black. 



Halteres pale ochraceous yellow. 



Wing with the usual pattern of the genus; base of subapical band 

 very narrow; basal band present, forming at apical process of anal 

 cell a diffuse translucent dark brown spot, which extends over anal 

 vein; costa at humeral cross-vein {th) and at termination of subcosta 

 not blackened, a small blackish brown dot on anterior termination of 

 th, and almost linear borders of the same color at tip of subcosta 

 (auxiliary vein). Stigma (= subcostal cell) long, nearly 2,8 times as 

 long as wide basally. First costal section 1.13 (1.13), second 2.61 

 (2.73), third 1.36 (1.32), and fourth 0.75 (0.82) mm. long; first section 

 of the fourth vein (Mi) 2.38 (2.45), penultimate section (between the 

 cross-veins) 0.54 (0.59), and ultimate section 1.93 (2.0) mm. long; inner 

 cross-vein {ta) 0.59 (0.66), outer cross-vein {tp) 1.13 (1.18) mm. long, 

 ta slightly longer than distance between cross-veins (= penultimate 

 section of Mi), and much more obliquely situated than tp; fifth longi- 

 tudinal (Ms+Cwi) vein which limits posteriorly the discoidal cell 

 hardly excurved; anal cell very long (1.82 (1.86) mm,), its apical
