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 Taeniorbyncbus, Mansonia, and possibly Anophelines. 

 Observe the hunchback attitude in the case of most of 

 the mosquitoes caught. If an Anofbeline 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.
