deep ochreous upright forked scales and small flat dull brown 

 ones laterally ; palpi shorter than the proboscis, thin, scaly, 

 brown, except at the actual base where they are testaceous, the 

 two apical segments are small, the penultimate a little longer 

 than the apical one, apex bristly (the exact number of segments 

 cannot be made out owing to the scales). Clypeus small, rather 

 long and bright testaceous. Proboscis brown, yellowish-brown at 

 the base, fairly long and swollen apically. Antennae with the 

 basal segment brown with a hoary sheen, testaceous in the cup- 

 like depression and with a very pronounced blunt prominence on 

 the inner side, the prominence has fine hairs on one portion, the 

 four following segments normal, the sixth to ninth with varied 

 processes as shown in the figure, the two long apical segments 

 very pubescent. Thorax deep shiny brown, with scattered bronzy- 

 brown narrow-curved scales at the base of the wings, the integu- 

 ment is pallid ; prothoracic lobes with dull grey flat scales ; 

 scutellum testaceous, with small narrow-curved black scales and 

 four black bristles to the mid lobe ; pleurae ochreous brown. 



Abdomen violet-black, with bronzy reflections in certain 

 lights, basal segment bright testaceous, with two spots of black 

 scales ; venter brown apically, yellowish-brown to ochreous

 unequal, the larger curved and thick and uniserrated, the smaller 

 simple ; the mid unequal, the larger much curved and simple, the 

 smaller uniserrated, hind very small, equal, simple and curved. 



Wings with the fork-cells short, the first sub-marginal longer 

 and narrower than the second posterior cell, its base nearer the 

 base of the wing than that of the second posterior cell ; its stem 

 more than two-thirds the length of the cell ; stem of the second 

 posterior a little longer than the cell ; supernumerary cross-vein 

 shorter than the mid, the mid longer than the posterior cross- 

 vein, the latter about three times its own length distant from the 

 mid ; scales on the branches of the fork-cells Taeniorhjnchus-MVa, 

 but small, on the steins and on the fifth and sixth veins median 

 vein scales alone present. Halteres with pale stem and slightly
