Genus Uranotaenia.

same width, its stem and upper branch very close to the first 
long vein, its stem nearly twice as long as the cell: stem of the 
second posterior cell about one and a third times longer than the 
cell; supernumerary cross-vein nearer the base of the wing than 
the mid cross-vein; posterior cross-vein a little more than its 
own length distant from the mid cross-vein. 
Halteres with a pale stem and fuscous knob. 
Length. —2*3 mm. 
<£. Head brown, with flat dusky black scales in the middle 
and creamy ones at the sides, and a few long black bristles 
projecting forwards; eyes black and silvery; 
proboscis brown, rather bulbous at the tip, as 
long as the antennae; antennae grey, with 
brown bands in the middle of the joints, from 
which spring the brown verticillate hairs ; basal 
joint dark brown and bright testaceous. Thorax 
much as in the 9 5 but a little darker brown 
and with more numerous and longer black 
bristles over the roots of the wings. Abdomen 
as in the 9 > but narrower and 
pubescent. Wings much as in the 9 ? but the 
posterior cross-vein is relatively much longer. 
Ungues of the mid legs very unequal, both simple, the larger much 
curved, the smaller nearly straight, hind claws equal and simple. 
Length .—-2*8 mm. 
Habitat .—Salisbury, Mashonaland (Marshall) (97). 
Time of capture .—March. 
Observations. —Described from a single and 9 • A third 
specimen is differently ornamented and is placed as a distinct 
variety (var. alba). This species can easily be told by the rufous 
thorax, with its brown flat curved scales dotted about, its fuscous 
abdomen, the verticils of the antennae arising from the middle of 
the joints, the much curved second long vein, and by the curious 
mid ungues of the male. It comes very close to Uranotaenia , 
but all the members of that genus I have seen have the scutellum

with flat scales. 
It may therefore have to be removed from this genus, but 
its venation, general form and head ornamentation place it so 
close to a typical Uranotaenia that I imagine the specimens 
may have had some of the scutellar scales removed as other 
parts of the thorax have; in any case it shows close affinities to 
this genus, differing only in the presence of a few curved scales
