border-scales ; first sub-marginal cell longer and narrower than 
the second posterior cell, its base nearer the base of the wing

Fig. 184.

cell; posterior cross-vein rather more than its own length 
distant from the mid cross-vein. Halteres with half the stem 
pale yellowish, the rest and the knob deep purplish-black, the 
knob densely scaled. 
Length. —3*5 to 4 mm. 
£. Head much as in the 9 > hut with rather more golden 
scales on the occiput; palpi much longer than the proboscis, 
entirely brown; the last two joints have fused into one, so that 
the palpi are really only two-jointed, unless we count a basal 
constriction; the last joint has dense black, long and thick 
bristle-like hairs, a few of which also arise from the preceding 
joint, the whole densely covered with brown scales; proboscis 
dark brown; antennae banded brown and grey, with dense 
brown plumes. 
Abdomen dusky black, the second to sixth segments inclusive
