and antennae deep black. Palpi slightly clavate, much contracted 

 at the base, apical segment minute. 



Thorax black, with bronzy-brown narrow-curved scales, paler 

 almost grey ones behind and at the sides forming lateral pale 

 lines, and a narrower one just over the roots of the wings ; 

 prothoracic lobes white scaled, separated from the rest of the 

 thorax by a prominent black line ; pleurae densely white scaled ; 

 scutellum with small flat grey scales and brown border-bristles, 

 four to the mid lobe ; metanotum deep brown. 



Abdomen deep brown with violet reflections, in some lights 

 under the microscope bright violet, each segment with prominent 

 apical lateral creamy spots, which in some segments spread 

 almost across the apical borders so as to form prominent pale 

 lines, but they never quite meet, except in the penultimate 

 segment ; the first segment testaceous, with large dense black 

 scales in two confluent spots, with brown bristles; border- 

 bristles very short, pale brown, shining apically. Yenter creamy- 

 white ; the apical spots are very pronounced on the ventral 

 surface in dried specimens, 



Legs jet-black ; under surface of femora, tibiae, and first hind 

 tarsal silvery-white \ ungues small, equal, and simple. 



Wings with brown scales ; fork-cells of moderate length, the 

 first sub-marginal cell considerably longer and narrower than the 

 second posterior cell, its base the nearer to the base of the wing ;, 

 stem of the first sub-marginal cell more than half its length ; 

 stem of the second posterior cell nearly as long as the cell ; 

 posterior cross- vein about twice its own length distant from the 

 mid cross-vein. 



Halteres with dull testaceous stem and fuscous knob. 



Length. — 4*5 mm. 



$ . Thorax and abdomen as in the 9 , but the abdomen 

 narrower and the apical lateral spots not quite so prominent. 



Basal lobes of genitalia densely bristly, bristles large, and 

 arise from distinct papillae ; claspers long and thin, simple. 



Antennae deep brown, with deep brown plume-hairs, pale 

 banding more or less noticeable ; proboscis black ; palpi shorter 

 than the proboscis, deep blackish-brown, no hair-tufts, the last 

 two segments of nearly equal length, the apical one slightly 

 shorter and with terminal bristles. 



Legs as in the 9 ; fore ungues unequal, the larger uniserrated, 

 the smaller simple ; mid ungues unequal, both simple ; posterior 

 ones very small, equal and simple, much curved.
