TWO TEXT FIGURES 



The studies and observations on which this paper is based 

 were conducted with the support and under the auspices of the 

 International Health Board of the Rockefeller Foundation. 



The work was done for the most part during 1915 and 1916, 

 and most of the anophelines studied were collected in Selangor 

 State, Federated Malay States. Certain details regarding the 

 method of feeding mosquitoes on gamete carriers, sele^ion of 

 material, dissection, and the like will be given in connection with 

 the tables or included in the description of the technic. 



In the identification of Malayan Anopheles I have depended 

 chiefly on the publications of Stanton, and I owe much to him 

 for personal aid in identifying certain specimens. The works 

 of Watson, Strickland, Leicester, and other observers in Malaya 

 have also been of much assistance, not only in the classification, 

 but also in the study of biological and epidemiological character- 

 istics of species.
