Genus Chrysoconops, 
445 
longer but the same width as the second, their bases nearly level; 
stem of the first fork-cell about one-fourth the length of the cell; 
stem of the second also about one-fourth the length of the cell; 
posterior cross-vein as long as the mid, sloping towards it, and 
about one and a half its own 
length distant from it; scales 
on the stem of the third and 
fourth very long. 
Length. —6*5 to 7 mm. 
Habitat .—Mpuma, Uganda 
(Sir David Bruce). 
Observa tions .—Described 
from one perfect female and 
one damaged one. 
It forms a very marked 
species which can at once be 
separated from other African 
Chrysoconops by the black spot 
near the base of the wing, by 
the very long and equal breadth 
fork-cells, by the very narrow 
dark apical leg banding and by 
the marked ornamentation of 
the thorax when viewed under 
the two-third power. The ab¬ 
domens in the two specimens 
vary in colour but the general 
effect is a golden-yellow hue in 
some lights, ochreous in others, 
with much dark violet-black 
coloration basally and the same dark coloration on the apical 
borders of the last few segments. The type in the British 
Museum collection I unfortunately broke, but the remains are 
sufficient to enable its identity, and part of the second specimen 
(damaged) is mounted in balsam. 
There seems to be some variation on the wings in regard to 
the colour of the scales, but the dark sixth vein and dark scales 
on some of the others and the marked yellow areas are 
characteristic.
