second fork-cell, their bases about level; stem of the first less 
than one-third the length of the cell, stem of the second fork-cell 
also less than one-third the length of the cell; posterior cross-vein

Length. —5*5 mm. 
Habitat. —Mpuma, Uganda (Sir David Bruce). 
Observations .—Described from a single 9 5 the abdomen lost. 
It is such a very marked species, however, that I have described 
it. Its general black appearance makes its identity an easy 
matter if it is examined under the two-third power, otherwise 
it may be confused with Mansonia (?) nigra , Theobald, from the 
Sudan. It differs in ; (1) the black forked cephalic scales ; (2) 
the venation; and (3) absence of heart-shaped scales on the sixth 
long vein.
