86 A Monograph of Culicidae. 



branch of the first fork-cell, all the rest with dense blackish- 

 brown scales ; first sub-marginal cell longer and narrower than 

 the second posterior cell, its base slightly nearer the base of the 

 wing, its stem nearly as long as the cell; stem of the second 

 posterior also nearly as long as the cell ; the scales are darkest 

 and densest at the costal region on the apical half, the region of 

 the cross veins and in the middle of the sixth and on the lower 

 branch of the fifth ; fringe without any pale spot. 



Halteres clothed with creamy scales, some dusky ones on one 

 side of the knob. 



Length. — 5 ' 8 mm. 



Habitat — Lagos (Dr. H. Strachan). 



Time of capture. — November (1905). 



Observations. — Described from a perfect $ . It comes very 

 close to M. umbrosus, Theobald, from Malaya, but can at once be 

 separated by the dense dark scaled wings and the peculiar 

 cephalic ornamentation. In the latter the front scales seem to 

 be intermediate between upright forked scales and narrow 

 curved ones, the line of chaetae bordering the eyes is also very 

 characteristic.

 species from Japan, where it was studied in connection with 

 malaria, which it was found to transmit.
