Favorite haunts of the adults. 



taking note at the time whether they are " culex " or " anopheles." 

 As each mosquito is caught, the tube containing it can be taken to 

 the light, and the mosquito carefully examined before transferring 

 it to the large bottle. 



In occupied houses and in barracks and hospitals, " anopheles " 

 are more likely to be found on dark-coloured clothes hanging in the 

 corners of the rooms or in the cupboards, or resting on the under- 

 surface of the shelves which usually surround the walls of barrack- 

 rooms. Saddles and harness of all kinds are also favorite resting 

 places of this kind of mosquito, and in the harness rooms of the 

 cavalry regiments at Mian Mir as many as twenty or thirty can 

 often be seen resting on the under-surface of each saddle hanging 

 up in the rooms. 



In stables and out-houses of Indian villages, it is usual for the 

 natives to store a number of dried mud and straw cakes which are 

 used for repairing their houses, and if one of these heaps of mud 

 cakes is kicked over, a large number of "anopheles" will often fly 

 out. In such a case as this a muslin net will be found very useful for 

 catching the mosquitoes as they fly out. With one sweep of the 

 net it is often possible to catch ten or twelve A. culicifacies after 

 disturbing one of these heaps, when it may be difficult to find any 

 specimens of this species resting on the walls or roofs of the houses. 



In addition to collecting the species which are commonly found 

 in the neighbourhood of habitations, it is very important to search 

 for those species which are seldom or never found in houses and 

 which may be termed " wild " species of " anopheles. " They may 

 sometimes be caught by the following method : On a night when 

 there is little or no wind a white sheet is hung near the ground 

 under some trees, and a lighted lamp is placed on the ground in 

 front of the sheet. The mosquitoes are attracted by the lamp and 

 alight on the white sheet, when they may be caught by placing a 

 test-tube over them in the usual way. Another plan is to erect a 

 tent in the jungle or other place where we wish to search for these 

 mosquitoes. After a day or two several will almost certainly be 

 found in the corners of the tent and beneath the folds of its 

 hangings. This method is of great service in villages where the 

 inhabitants are unwilling to permit search being made in their 

 houses.
