37. A. mauritianus, Grandpre, Planter's Gaz. Press (1900). 



A. paludis, Theo., Royal Soc, Rept. Malaria Com. p. 75 (July 6, 1900). 



The tarsal character given by Theobald for separating mauritianus and paludis 

 breaks down, and I feel sure there is really only one species. There is, however, 

 a fairly constant difference between specimens from East and West Africa ; in 

 the former there is a broad white patch embracing the apex of the hind tibia and 

 the base of the metatarsus, on the upper surface : in the latter, which may be 

 known as var. paludis, the patch is very narrow and inconspicuous. 



Widely distributed in Africa, but as a rule uncommon. In Nairobi, British 

 East Africa, however, it appears to be the commonest Anopheles. 



I have been unable to consult Grandpre's original description, and do not know 

 whether his name has priority. It lias been retained because the form with a 

 black spot at the base of the 3rd hind tarsal joint is by far the commoner, both 

 in East and West Africa.

It is possible that this species may prove to be identical with A. bifurcatus, L.

I have been unable to examine this species.
