Genus Mansonia. ie 
Wings with the veins densely clothed with Mansonia scales, 
the third and fifth long veins with underlying Taeniorhynchus-like 
scales, the scales are mostly dark, but many pale ones are dotted 
about ; border-scales of Taeniorhynchus form ; first sub-marginal 
cell longer and narrower than the second posterior cell, its base 
a little nearer the apex of the wing than that of the second 
posterior cell, its stem less than one-third the length of the cell; 
the posterior cross-vein from two and a half to three times its 
own length from the mid cross-vein. Halteres with ochraceous 
stem and fuscous knob. 
Length.—6°5 mm. 
Habitat.—Bahr el Ghazal, Central Africa (Capt. Cummins, 
R.A.M.S8.). 
Observations.— Described from a single 9 somewhat damaged, 
but so marked from the other African Mansonia that I have 
ventured to describe it ; although the specimen is squashed, all 
the scaled structure is apparent, except on parts of the abdomen. 
It can at once be told by the golden-brown scaled thorax, with a 
pale silvery patch in front of the scutellum. It is also much 
larger than M. uniformis and has the first sub-marginal cell 
considerably longer in proportion. The border scales are all dull 
yellow, and so again differ from M. wniformis.
