marginal cell considerably longer and slightly narrower than 

 the second posterior cell, its base slightly nearer the base of the 

 wing than that of the latter, its stem 

 variable, from one-half to one-fourth the 

 length of the cell ; stem of the second 

 posterior about two-thirds the length of the 

 cell ; posterior cross-vein rather more than 

 its own length distant behind the mid cross- 

 vein ; halteres with reddish-brown stem, 

 fuscous knob with a few grey scales.

$ . Head deep brown, with narrow- 

 curved grey scales with a median dividing line, numerous upright 

 black and ochreous forked scales and some black bristles ; palpi 

 dusky-brown almost black along the two apical segments and on 

 the apex of the antepenultimate, traces of a pale band (very 

 narrow) towards the base ; hair-tufts deep brown ; proboscis deep 

 brown, thin. 



Thorax much as in the female, but the scanty ornamentation 

 not so distinct; pleurae pale with indistinct patches of grey 

 scales. 



Abdomen deep brown, hairy, the segments with basal white 

 lateral spots, the last segment with basal white band, posterior 

 border-bristles pale golden, short, lateral hairs very long, golden- 

 brown; basal segment testaceous with two prominent tufts of 

 black scales ; owing to scanty scaling the abdomen appears to be 

 basally pale banded.
