THE DOMESTIC MOSQUITOS OF ACCRA. 



177 



Table VII. — continued. 



Summary and Conclusions. 



1. An examination of the mosquito larvae found in domestic water-receptacles, 

 etc., in native compounds at Accra shows that two species, Stegomyia fasciata and 

 Culexfatigans, predominate, and that of these the former is by far the most common. 



2. Such an examination, however, fails to give a true idea of the mosquito fauna 

 of the town, or of the species to the attacks of which the inhabitants are exposed. 

 Many of the species most common in the houses do not breed in the compomids, but 

 come from further afield, where their larvae should be sought out and destroyed.

[With reference to the supposed non-existence of Culexfatigans in Lagos, Dr. J. M. 

 Dalziel, who has recently been investigating the domestic mosquitos of that town 

 has kindly supplied the following records of the occurrence of that species : — 

 " July 1914. One adult caught in neighbourhood of the golf course 

 marsh. 

 Sept. 1914. One adult caught in Government House or environs. 

 Aug. 1915. Bred from larvae from wells — twice.
