Inspections for determining mosquito indices in Freetown were 

 made quarterly, with the following results :• — (1) 16th to 19th March, 

 0'4 per cent. ; (2) 2nd to 6th June, ll'e per cent. ; (3) 9th to 17th 

 September, 25*2 per cent. ; (4) 11th to 30th December, 3 "2 per cent. 

 In the September examination, 54 out of 63 breeding-places were in 

 water-bearing plants and the mosquitos breed from the larvae 

 included :■ — Culex tigripes, Eretmopodites inor'}%ata, E. quinquevitattus, 

 Stegomyia simpsoni, and S. fasciata. 



The presence of Stegonujia in vessels other than ocean-going steamers 

 at Freetown was investigated. In thirteen vessels lying on shore, not 

 in actual use and containing fresh water, were found the larvae of 

 Stegomyia fasciata, S. sugens, Culex duttoni, and C. pipiens. C. pipiens 

 and S. sugens were also bred from fresh water in lighters in 

 the harbour. Six examples of Anopheles (Pyretophorus) costalis were 

 found on a wreck a mile from the shore. 



Examination of the natural breeding places of mosquitos in Freetown 

 demonstrated the presence of : — Culex decens, C. duttoni, C. tigripes, 

 Stegomyia fasciata and Anopheles costalis. In artificial breeding places 

 C. decens, S. fasciata, Culiciomyia -nebulosa and A. costalis were found.
