Head wholly yellow, the occiput opaque and covered with grey pollen, the face 

 and frons shining, especially the last, which is highly pohshed ; all the bristles are 

 yellow, those of the occipital row short and thin. Antennae, palpi, and proboscis 

 yellow. 



Thorax wholly yellow, with pale pubescence and yellow bristles ; on the back it 

 is dark ferruginous, a broad notopleural band is light yellow, the pleura are also paler. 

 The black dots are : two pairs in the middle after the suture, shining, bearing the prsc. 

 and the dc. ; two on each side in the notopleural depression, larger and velvety-opaque, 

 one below the prst., the other before the first sa. ; besides there is another black spot 

 below the post-alar callus and one smaller at the root of the wings. Scutellum like 

 the thorax, but without black spots ; haltères and squamulae yellowish. Abdomen 

 entirely reddish yellow, with pale pubescence and numerous but short yellow bristles 

 on the sides. Ovipositor shining reddish, as long as the three last 'abdominal seg- 

 ments. Legs wholly yellow ; front femora below with 5-6 very long and strong bristles ; 

 hind tibial row very developed, the bristles being black, and disposed like a comb. 



Wings wholly hyaline, with yellow veins ; the stigma long, entirely yellow, of the 

 same colour as the costal band. Costal band extending in almost equal width from the 

 base to the tip of the wing ; it reaches below the third vein, but just after the small 

 cross- vein leaves a narrow hyaline streak in the middle of the submarginal cell. The 

 colour of this costal border is light yellow, but it includes some dark spots, one lighter 

 in the costal cell and two darker towards the end of the marginal cell ; the arcuate 

 tip, from the end of the second to the end of the third vein, is, moreover, blackened. 

 The yellow posterior ray begins in the anal cell and runs along the fifth vein, being 

 much broader below than above ; at the apex it rejoins the hind margin of the wing ; 

 its colour is paler yellow than the fore border.

Distinguished by the prominent epistome, the long and geniculate proboscis, the 

 4 bristles of the scutellum and the banded wings with very approximate cross- veins. 



Head broader than high ; the frons rather long and depressed, broad, prominent ; 

 face short and very concave, the epistome strongly prominent and cutoff; antennae 

 inserted below the middle of the eyes, reaching the epistome, the third joint a little 

 shorter than twice the second, a little pointed at the upper corner ; arista bare ; pro- 

 boscis long, geniculate ; palpi not bristly. Oc. strong ; or. 1. 2 ; pvt. divergent ; 

 bristles of the occipital row strong, whitish ; genal bristle less developed. 



Thorax with paler pubescence and complete chaetotaxy, but the scp. less distinct ; 

 only a strong mpl. Scutellum with four bristles of almost equal size, the apical pair 

 crossed, at least at the end. Abdomen with apical bristles ; ovipositor short and 

 flattened. Legs short and strong ; front femora with a less developed row of bristles 

 beneath ; middle tibiae with a single spur ; hind tibiae with some short hairs. 



Wings narrow and elongate with small costal bristle ; first vein short, not reaching
