white, there are also scattered white scales over the upper 

 surface of femora ; ungues all equal and uniser rated.

 dense ; first sub-marginal cell longer and a little narrower than 

 the second posterior cell, their bases nearly level ; stem of the 

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

stem of the second posterior cell about three-fourths the length of 

 the cell ; posterior cross-vein about the same length as the mid, 

 and a little more than its own length distant from it ; halteres

$ . In the male there is a trace of a narrow indistinct line 

 of pale scales in the middle of the mesothorax. Palpi deep 

 blackish-brown, last two segments enlarged, with dense brown 

 hair-tufts and similar coloured hairs at the apex of fche ante- 

 penultimate segment ; antennae with dense deep brown plume 

 hairs with flaxen reflections. Fore and mid ungues unequal, the 

 larger fore ungues biserrate, the smaller uniserrate ; mid ungues 

 unequal, but not so much so as the fore, the smaller uniserrate, 

 the larger with one large tooth, and traces of a smaller basal 

 one ; hind ungues equal and uniserrate. Claspers long and 

 curved, flattened, apical segment long, dark brown, with a small 

 spine at the base ; harpogones expanded at the apex, chopper 

 shaped ; two median short, dark, thick curved hooks. 



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

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

 base of the wing, its stem nearly as long as the cell, stem of the 

 second posterior longer than the cell ; posterior cross-vein not as 

 long as the mid, its own length distant from it. The apical 

 segment of palp shorter than the penultimate and slightly 

 narrower, apex of the ante-penultimate swollen with a tuft of 

 chaetae, one side arising from well-marked tubercles, the long
