second band is narrower and placed on the fore border of the fourth segment ; the 

 5th segment is also blacky forming a third narrow band in front of the ovipositor ; 

 the latter is as long as the four last segments, swollen, shining ferruginous with a 

 black end. In the male the first band covers only the hind margin of the second 

 segment, and the third band is not present. The third and fourth segments have a 

 rather whitish colouring. Male genitalia prominent, shining black, with projecting 

 yellow organs. Legs of the male entirely yellow ; hind femora of the female darkened 

 at the end. 



Wing-pattern like that of the preceding species; stigma entirely brown, with a 

 small yellowish dot on the apical corner ; the first brown band from the stigma runs 

 hindwards between the first and fourth veins to the root of the wing ; second band 

 and anterior arcuate border as in the preceding ; the apical brown streak is united 

 to the fore border through the middle of the last portion of the third vein ; the band 

 on the hind cross- vein is isolated and much widened at the hind margin.

 the middle and the lower occipital orbits pale cinereous; antennae yellow, the arista 

 darker and deeply plumose; palpi light yellow, pale-haired, with 2-3 short black

 broad parallel ferruginous stripes which extend to the dc. ; humeri, notopleural region 

 and two large lateral spots before the scutellum whitish. Pleura black, shining, a 

 large white patch filling the mesopleura and the anterior part of the pteropleura and 

 forming with the humeral and notopleural patches a single ver}^ striking oblique band . 

 Pubescence of the pleura rather long, whitish, on the lower portion of sternopleura 

 thicker. Metanotum black, with the usual white lateral spots; hypopleura white. 

 Scutellum shining black, with two lateral whitish yellow spots, in the middle of which 

 are inserted the basal bristles. Haltères pale yellow.
