To Capture Anophelines 
Necessary Apparatus .—One or two small collecting 
tubes, a clean and perfectly dry bottle (whiskey bottle), 
some cotton wool (Fig. 34). 
To Detect Anophelines 
Choose a suitable native village, i.e ., in Africa, 
any bush village; or in India, any village near a nullah 
or other source of Anopheline larvae. 
Determine whether Anophelines exist in any of 
the following situations :— 
1. In the dark corners of sheds, cow-houses or 
other out-houses. 
2. Under the eaves (in darkish parts) of the huts. 
3. In the huts themselves, hanging to straws, 
stalactites of soot, etc., etc. 
4. Any other likely situations, e.g ., collections 
of dry grass ; in the undergrowth in the bush (capture 
in this situation is difficult). 
If, on inspection, none of the insects can be 
detected by careful scrutiny (the most concentrated 
attention is, as a rule, needed), the thatch should be 
carefully disturbed with the hand or a short stick. 
To Detect Culex 
Examine the walls of houses, out-houses, and 
native huts. Examine especially clothes hung up in
