smaller and duller ones at the back ; over the whole surface very 

 long deep black upright forked scales. Proboscis black, with a 

 pale ochreous band slightly towards the apical half. Palpi deep 

 brown and densely scaly ; clypeus brown. 



Thorax rich deep chestnut-brown, with scattered golden 

 curved scales ; silvery white flat scales on the prothoracic lobes ; 

 numerous black bristles over the roots of the wings. Scutellum 

 brown, clothed with silvery white flat scales and black border- 

 bristles, six to the mid lobe and some smaller ones with them ; 

 pleurae brown, with prominent silvery puncta composed of flat 

 scales. One large spot of these scales seems to project outwards, 

 and can be seen when the insect is viewed from above, looking 

 almost like a silvery spot close to the roots of the wings. 



Abdomen deep brown, with basal white lateral spots and pale 

 venter. 



Legs black, with apical silvery white bands as follows : small 

 but prominent on all the femora and tibiae of all the legs, on all 

 the first tarsals and on the fore and mid second tarsal segment ; in 

 the hind legs prominent on all the segments, the last tarsal being 

 pure white. All the ungues equal and uniserrated. Wings with 

 the first sub-marginal cell longer and narrower than the second 

 posterior cell, its base nearly level with that of the second 

 posterior cell, stem of the first sub-marginal about two-thirds the 

 length of the cell, stem of the second posterior as long as the 

 cell ; posterior cross-vein nearly twice its own length distant 

 from the mid. Halteres with pale stem and fuscous and white 

 knob. 



The scales of the wings are deep brown, especially along the 

 costa, with deep violet reflections along the base and a white 

 patch at the base of the costa and first long vein. 



Length. — 4 ■ 5 mm. 



$ . Palpi about the same length as the banded proboscis, 

 the two apical segments small and about equal, a pale band at 

 the base of the apical segment ; on both apical segments and on 

 the apex of the antepenultimate a few long brown hairs. Fore 

 and mid ungues unequal, the mid more so than the front ones, 

 both uniserrated, the tooth of the larger mid unguis near the 

 base and small. 



Length. — 4 to 4 • 5 mm.
