2. Examine, with a light, some wall which has 
been only dimly illuminated by the lamp, i.e ., some 
wall at the distance of several yards, and note true 
mosquitoes resting upon this. Capture several of 
these by placing a tumbler over them, and kill them by 
puffing in a little tobacco smoke. 
The specimens caught will probably be specimens 
of Culex. If near a swamp or jungly place there may 
be T aeniorhynchus, Mansonia , and possibly Anophelines. 
Observe the hunchback attitude in the case of most of 
the mosquitoes caught. If an Anopheline should by 
chance be caught, note the striking difference in the 
general appearance, the attitude, and the spots on the 
wings. 
3. Observe in stuffy, furnished rooms, offices, etc., 
the presence of mosquitoes feeding actively during the 
day. Capture some of these. They will probably 
belong to the genus Stegomyia. Note their extreme 
alertness. Observe that they are black with white 
bands. Note the habit of waving the hind legs, and 
that the tarsi of these are kept curved. Ascertain 
whether the males feed upon blood. 
4. Examine stables, huts, outhouses, bridges, 
drains, etc., in the early morning.
