Melanoconion, but the apical wing scales as seen in the ? are not 
of the type found in that genus. The abdomen is peculiar in that 
the base is contracted, giving it a waist-like appearance in both 
sexes, but this is possibly due to shrinkage. The two pale 
patches, one on each side of the mesonotum, are also very 
characteristic, but vary in size and intensity ; they are due to 
the prothoracic scales being pale. The abdomen presents a false 
banded appearance in some lights, the light basal bands being 
due to the light shining through the less scaled basal areas of 
the segments. 
The forked scales on the head in the specimens taken at 
Entebbe are black and ochraceous, and the abdomen is not con- 
stricted basally to the same extent. 3 
Dr. Dutton bred two 9’s from larvae taken from pools at 
Box Bay, Gambia. The venation is slightly different, the relative 
length of the fork-cells varying considerably. 
The larvae are emerald-green as well as the pupae. They 
may be found in pools of stagnant water. They are of larger 
size than one would expect from the size of the insect.

the basal one, the third much the longest, and there is apparently 
a small fourth apical joint; clypeus deep brown ; antennae deep 
brown, with pale pubescence and deep brown verticillate hairs, 
basal joint testaceous, with a few pale scales, second joint also 
testaceous at the base, with a few pale scales on the inside.
