A NEW MOSQUITO (AEDES WHITMOREI) FROM COLOMBIA 



BY LAWRENCE H. DUNN, 



Lieut., Sanitary Corps, National Army, Army Medical School, 



Washington, D. C. 



Aedes Whitmorei, new species. 



During 1916 the Rockefeller Foundation International Health 

 Board sent a commission of six experts sanitarians to South 

 America for the purpose of studying the yellow fever conditions 

 existing at that time. This commission consisted of Major 

 General William C. Gorgas, Dr. Juan Guiteras,, Dr. Henry R. 

 Carter, Major T. C. Lyster, Major Eugene R. Whitmore and Mr. 

 William D. Wrightson. 



While the party was in Colombia, Major W T hitmore collected 

 specimens of mosquitoes prevalent at several places that were 

 visited and made as complete a mosquito survey as tune and con- 

 ditions permitted. As specimens were taken on board ocean going 

 steamers, on river boats, in low lying coast, and in villages located 

 on the upper plateaus at higher altitudes, an interesting collection 

 was obtained. The writer was recently afforded an opportunity 

 to examine the specimens collected on this trip and found one 

 species to be new and previously undescribed. This species is 

 named in honor of the collector, Major E. R. Whitmore.
