The number of these larvae in close proximity to a house may be great, an 
yet the number of adults that enter the houses very small. It is not ti 
clearings become larger that such mosquitoes become truly domesticate! 
In the larger clearings such as the smaller township or suburbs with littli 
or no jungle close to the houses these mosquitoes are found in abundant 
in the houses and breed in water such as in water jugs or bath tubs in a 
well as outside the houses. Stegomyia scutellaris is therefore capable c 
domestication and under such circumstances may be found in large number 
Many other of the jungle mosquitoes are found from time to time i 
houses and bite freeiy, but do not appear to become domesticated or to bree 
in the houses, e.g., Leicesteria. To these may be added the widely distribute 
country mosquito, which is not restricted to jungle districts, Mansom 
nniformis. 
1 he mosquito which is most persistently met with in houses and rarel 
found away from them is Culex fatigans. In the jungle it is not found, no 
as a rule in small clearings in jungle, but as soon as a small village is forme 
it appears and becomes very numerous, breeding freely in almost an 
stagnant water, and particularly in water, however foul, contained in jarsc 
other artificial vessels. Anopheles Rossii, Kochu , and Barbivostris , tire rarel 
found at any distance from human settlements. 
Towns. 
The mosquitoes prevalent in a town such as Kwala Lumpur vary i 
each part. In all (Sulex fcitigcins is found, but it is in the crow ded parts an 
particularly near Chinese quarters that it becomes a real pest. In th 
purely European part where houses are at some distance from each other, i 
care be taken about drains, storage of water, etc., the number of mosquitoe 
found will be small, but, however great care is taken, these and the hardie 
jungle mosquitoes will from time to time be found. 
Coast Lands. 
1 roximity to the coast is a cause of much greater difference that 
altitude. Mosquitoes are found there which are found nowhere else, anc 
many of the common inland species are absent. 
Observations w r ere made at Port Swettenham and the low-lvinj 
mangrove swamps around it; at Jugra, where the coast lands are partly o 
the same character, but with a granite hill 915 ft* high close to it ; nea 
Port Dickson, where there is a clean sandy beach and the land behind i 
well drained and elevated; and at an island, Pangkor Laut, which is c 
granite formation with rocky edges and small stretches of sandy beach. 
At Pangkor Laut the mosquitoes found were similar to those met wit! 
inland granite formation. No new species were found. There were nc 
bamboos, but in a hollow in a tree trunk Toxorhynchites metallicus anc 
species of Orthopodomyia differing only in colouring of last tarsal joints o 
the hind legs from that common in bamboo was found. 
• Treacherii was found in the streams on the side of the steep hills 01 
this island and was also found in the granite hills behind Jugra, but not ir 
the flat coast lands, so that the unhealthiness of most of the coast districts 
cannot be attributed to this mosquito. 
Tn hollows and holes in granite boulders various species of mosquitoes 
were found, including, according to Dr. Clark, one species of anopheles.
