that malaria is present, and even a small number of them is 

 usually accompanied or immediately followed by new cases, the 

 number (of cases) depending largely on the prophylactic control 

 of the station."'^ 



Nothing occurred to suggest to me that an error had been made 

 in referring this species to A. fimesius until the spring of 1912, 

 when in discussing some Philippine mosquitos with Dr. Malcolm 

 Watson, Chief Medical Officer, Estate Hospital Association, Klang, 

 F. M. S., who was in Washington at that time, he called my atten- 

 tion to the fact that the dark species under consideration had a 

 hght ventral apical portion on the proboscis, and it seemed possible 

 that it was an undescribed species. I gave Doctor Watson speci- 

 mens of various Philippine mosquitos which he took to Mr. F. W. 

 Edwards (British Museum) for confirmation of my naming, and 

 at once wrote me that what I had called funesta Giles was really 

 christophersi Theob. In the meantime I published a description 

 of the dark specimens as Myzomyia flavirostris. 



Mr. Edwards also kindly wrote me in regard to the matter, 

 saying there could be no doubt as to the naming of the species, es- 

 pecially as Mr. Theobald's types in the British Museum were " for- 

 tunately in good condition. The type of christophersi has two 

 broad apical bands like your funesta. On the other hand both 

 funesta Giles and listoni Liston \vaxe female palpi with three 

 narrow bands," and in a later letter writing in regard to specimens 

 I had sent him, Mr. Edwards writes '"'M. funesta Giles' and 'M. 

 flavirostris Ludl.' both, as you suggest = christophersi." 



In preparing the manuscript of "Bulletin No. 4, Surgeon Gen- 

 eral's Office" in 1913, as this species had heretofore been reported 

 to the Medical Corps, U. S. Army as "M. funesta" it seemed wise 

 to retain the name and Giles description and add a footnote ex- 

 plaining the error which had occurred, and giving the correct name 

 and synonomy, which, with the description of flavirostris imme- 

 diately following, it was believed would make the matter quite 

 clear. 



It was therefore a surprise to find Mr. Banks had redescribed 

 this species as A . fehrifer ^ and that Messrs. Walker and Barber in 



' The observations on which these statements were based began in 1901 and therefore cov- 

 ered several years.
