 tapered ; vestiture bronzy brown, darker towards tip ; setae minute, curved, black, 

 those on labellos more prominently outstanding;. Palpi small and slender, one- 

 fifth as long as proboscis, black, with a few outstanding setae. Antennse with 

 basal joints somewhat shorter than apical ones, rugose, pilose, black, second 

 joint slightly enlarged ; tori subspherical, with a cup-shaped apical excavation, 

 brown, blackish on inner side ; hairs of whorls sparse, moderate, black. Clypeus

 except the first and second, joining a row of lateral triangular segmental spots ; 

 venter clothed with yellowish-white scales, without distinct bands; a row of 

 yellowish hairs at tip of each segment dorsally. 



Wings moderate, hyaline; petiole of second marginal cell about one-third 

 as long as its cell, that of second posterior cell a little shorter than its cell ; basal 

 cross-vein about its own length distant from anterior cross-vein ; scales brown, 

 with a bronzy luster on costa, linear, denser towards apex, especially on forks of 

 second vein. Halteres whitish. 



Legs moderate, femora whitish beneath nearly to tip ; tips of hind tibiae pale ;
