2 . Length of antennae, 2.27 millimetres. 
Expanse of wings, 3.81 x 0.88. 
Size of body, 4.31 x 0.88. 
Antennae brown, the length of the proboscis ; first joint of the 
scapus and basal half of the second joint testaceous. Head 
deep brown, nearly black with yellow scales. Proboscis deep 
brown, nearly six times the length of the palpi, with a prominent 
broad ring of white in the middle one-third the length of the 
proboscis. Palpi black or deep brown, the third and last joints 
almost imperceptibly tipped with white. Thorax deep brown, 
rather densely covered with yellow scales and hairs ; pleurae 
deep brown, spotted with a few small patches of white scales ; 
a little testaceous under the origin of the wings ; scutellum 
somewhat testaceous-brown, with long yellow hairs ; metanotum 
deep brown. Halteres brownish-ochraceous. Abdomen twice 
the length of the thorax, deep brown, nearly fuliginous ; each 
segment bordered anteriorly with a narrow band of white scales 
and fringed posteriorly with golden-yellow hairs ; underneath 
covered with white scales. Coxae reddish-brown, with white 
scales. Femora deep brown above, white beneath (in the fore 
and intermediate pairs the brown predominates), and just 
perceptibly white at the extreme apex ; tibiae and tarsi sordid 
brown, with a yellowish-grey reflection, all joints, except the 
last tarsal joint, with a small ring of white at the base. In the 
hind-legs the metatarsi equal in length to the tibiae. Wings 
longer than the abdomen, hyaline, the veins thickly covered 
with brown scales, chiefly long and very slender, cilia brownish- 
grey. Auxiliary vein reaching the costa about opposite the tip 
of the posterior branch of the fifth longitudinal vein ; middle 
and posterior cross- veins very pale, the former a little shorter 
than the latter and situated in front of it a distance equal to 
twice its length ; first sub-marginal cell a little longer and 
distinctly narrower than the second posterior cell, its base situated 
almost opposite but slightly beyond the base of the latter ; 
anterior branch of the fifth longitudinal vein originating at a 
point about mid-way between the origin of the second longi- 
tudinal and the tip of the sixth longitudinal, joining the margin 
opposite the middle of the second posterior cell. 
$ . Head with creamy upright forked scales on each side in 
front, dusky ones behind, a bare line in the middle ; grey and 
brown flat scales at the sides ; antennae brown, with pale bands 
and dark silky-brown plumes ; palpi dark brown, with two broad 
basal pale bands and two narrow ones to the apical joints, the 
one broad band corresponds in position with the proboscis band ; 
proboscis banded in the middle, expanded towards the apex, 
which darkens and then becomes paler, not so long as the 
palpi ; ungues of fore and mid legs unequal, both serrated,
