In fifty-three cases therefore or 84 per cent. of the total finds, the larvæ were obtained in the stored clean water used for drinking, cooking, etc.
In the remaining eleven cases, the finds were made three times in miscellaneous jars in yard, twice in flower pots, once in a wooden tank for soaking bamboos in (Chair Makers), three times in jars in Preserved Fruit Factories, once in a jar in a woodyard and in one case no record of the jar was made.
In all cases the finds were made in densely built over areas either in the houses themselves or in their immediate vicinity.
The habits of Stegomyia fasciata here are therefore the same as in other parts of the world with the important exception that it is not usual to find it breeding in miscellaneous receptacles such as old jars, cans, tins, etc., as described by Sir Rubert Boyce and other authorities.
Careful and prolonged search has been made of these miscellaneous breeding places both in this investigation and by Dr. J. C. Thomson in 1902.
In Dr. Thomson's case no fasciata at all were found, and in the present investigation they have only been found in these receptacles to a very limited extent.
Stegomyia scutellaris which is to be found breeding in practically every such collection of water here apparently occupies the place taken by Stegomyia fasciata in other parts of the world.
With the exception of a few licensed premises none of the Chinese houses in Kowloon have water laid on.
All water for drinking, cooking, etc., has therefore to be carried from stand pipes in the street and stored in the kitchen or yard in wooden barrels, earthenware jars (kongs), iron pails, etc.
