negative results were obtained. Further investigation of these apparently 

 favourable localities is desirable. 



Since the presence of larvae oi A. maculipennis has now been observed 

 as far within the urban district of London as Chelsea, records are needed 

 of the occurrence of adults in this area. Up to the present time adults 

 have only been recorded from suburban localities (Acton, Mitcham, etc.) 

 all lying at a considerable distance from Charing Cross. 



In order to make this report as complete as possible, previous records 

 have been incorporated into it. All such records have been drawn from 

 W. D. Lang's Map showing the known Distribution in England and Wales 

 of the Anopheline Mosquitoes, with explanatory Text and Notes, published 

 by the British Museum (Natural History), 1018. The Local Government 

 Board's Reports and Papers on Malaria contracted in England in 1917 

 (New Series, no. 119, 1918) has also been consulted, but contains no 

 additional information on the London area. 



The writer is extremely indebted to Mr W. D. Lang for his kindness 

 in identifying numerous larvae and adults, to Mr A. J. Grove (Acting 

 Entomological Investigator, Local Government Board), and to Mr Hugh 

 Scott for his assistance throughout the course of the investigations.
