96 Records of the Indian Museum. [Vou. VII, 
The most common situation in which larvae were found 
during the rainy season was in earthen pots, except in the case 
of one species (Myzomyia rossit) which was found chiefly in open 
drains, but during the other two seasons, tanks, open drains, 
cisterns, cesspools and earthen pots were all utilized as breeding 
places with about equal frequency. Other artificial collections of 
water, such as that in tubs, metal cans, iron and earthen pans 
also served as breeding places, but did not seem to be patronized 
very much by mosquitoes ; probably because some of these were 
less common, whilst others, being shallow, quickly dried up. In 
one instance, a canal served as a breeding place for Myzomyia rossi. 
Table VI shows the number of specimens of each species that 
emerged during each of the three different seasons and their relative 
percentage. It will be seen that Culex A was the most abundant 
mosquito in allthe seasons. Myzomyia rossti was commoner during 
the hot and rainy seasons than during the cold weather. The 
largest number of mosquitoes emerged during the rainy season, 
being as much as 69°9% of the year’s total, clearly indicating 
that the larvae were more easy to obtain at this time than at 
any other. 
The larvae of Culex A were found mostly in open drains 
during all the seasons. 
Larvae of Culex B were found in about equal proportion in 
tanks, open drains and earthen pots during the rainy season, and 
in open drains during the hot season. 
Culex A (with the proboscis unbanded) belongs rightly to the 
fatigans group of that genus, and I have noticed all varieties, both 
in respect to size and markings, emerge from a batch of larvae 
collected at one time from a single piece of water. 
The forms of Culex with the banded proboscis (Culex B) be- 
long to the impellens group. 
These were the only two forms of the smaller species of Culex 
which emerged from larvae received during the year’s survey. 
Larvae of Culex concolor, Desv., were not very plentiful and 
were chiefly found during the rainy season in small collections of 
water, vz., cesspools, tubs, iron pans and earthen pots, in com- 
pany with larvae of Culex and Stegomyia, These larvae are of 
carnivorous habits and small collections of water are most suitable 
for them as they can easily capture any other larvae which may 
breed along with them in these situations. 
Larvae of Leucomyta gelida, Theob., were only common during 
the rains, and were obtained chiefly from earthen pots, although 
some were got from tanks and open drains. This species appears 
to be entirely absent in the ‘‘ Fringe Area ’’ during the other two 
seasons. 
Larvae of Stegomyia scutellaris, I,., were procured in very large 
numbers during the three seasons from earthen pots, but chiefly 
during the rains. 
During the other two seasons larvae were obtained from open 
drains and metal cans as well.
