A COLLECTION OF MOSQUITOES FROM THE 

 PHILIPPINE ISLANDS 



(Diptera, CuUcidce) 



By HARRISON G. DYAR 



A collection of 640 mosquitoes was sent me by Prof. C. F. 

 Baker, Dean of the College of Agriculture, Los Baiios, Luzon, 

 Philippine Islands. The collection was made by students of 

 the college, mostly in 1915. Thirty-two species are contained 

 in the collection, a large number for a single locality, but 

 probably by no means exhaustive. A recognition table of 

 these species is added for the convenience of the college.
