A — Average number of QQ of Myzomyia ludlowi THEOBALD captured, 
by means of mosquito-nets, per 10 M? and per night at different salinities. 
For each salinity class the averages are derived at once from all the 
data collected throughout the entire Batavia empang zone. 
a — Average number of 22 of Myzomyia ludlowi THEOBALD captured, 
by means of mosquito-nets, per 10 M? and per night at different salinities. 
The averages were obtained by determining for each salinity class the 
average of the local averages calculated for the different parts of the 
Batavia empang zone. 
A B — Number of 99 of Myzomyia ludiowi THEOBALD per 100 99 of 
Myzomyia rossii GILES at different salinities. For each salinity class 
these numbers are derived at once from the total numbers of both 
Anophelines captured by means of N throughout the entire 
Batavia empang zone. 
A’ B’=Number of 22 of Myzomyia ludlowi THEOBALD per 100 22 of 
Myzomyia rossii GILES at different salinities. For each salinity class 
these numbers are derived at once from the total numbers of both 
Anophelines emerged from larvae and pupae collected throughout the 
entire Batavia empang zone. 
B = Averages relating to the production of Myzomyia rossti GILES which 
serve for comparison with the corresponding figures concerning the 
production of Myzomyia ludlowi THEOBALD mentioned after A. 
b = Averages relating to the production of Myzomyia rossit GILES which 
serve for comparison with the corresponding figures concerning the 
production of Myzomyia ludlowi THEOBALD mentioned after a.
