 species with four large black spots, formed by clumps of 

 scales, on the wings. 



2. African Species. 



Anopheles algeriensis, Theobald. Found in Algiers. Like 

 A. bifurcatus (see above) but lighter in colour and smaller : 

 probably a variety. 



Anopheles smithii, Theobald. Found in Sierra Leone. 

 The wings are not spotted and the legs are not banded, but 

 the palps have three narrow pale rings. Mr Theobald speaks
