 Wing of Culex stoehri. ? . n. sp. 



cell about two-thirds the length of the cell ; supernumerary and 

 mid cross-veins not meeting exactly together, the posterior cross- 

 vein longer than the mid, sloping backwards, and about twice its 

 own length distant from it. 



Length. — 4*5 mm. 



Habitat. — British Central Africa (E. 0. Stoehr). 



Observations. — Described from a perfect J . The thoracic 

 adornment is very marked and characteristic when viewed with a 

 hand lens, but this is not seen under the microscope ; the three 

 darker markings being due it seems to slightly more scanty 

 scaling and the direction of the scales. 



The thorax is very distinct from C. fatigans, which it closely 

 approaches, the scales having a dull, in some lights almost fawn 

 coloured shade.

 median area ; proboscis unbanded. Thorax uniformly dusky 

 brown. Abdomen deep brown, unbanded, but the pale border 

 bristles giving a quasi-banded appearance. Legs brown, unbanded. 



$ . Head deep blackish-brown, with narrow-curved pale 

 scales which are very scanty except in the middle line, so that 

 the head appears dark ; flat grey and creamy grey lateral scales
