THE EARLIEST NAME OF THE YELLOW FEVER 

 MOSQUITO 



By FREDERICK KNAB 



A single species of mosquito has been definitely connected 

 with the propagation of yellow fever. This mosquito is well 

 known and widely distributed ; in fact, it occurs in association 

 with man throughout the tropical and semitropical parts of 

 the globe. Since the discovery that this mosquito is the vector 

 of yellow fever, it has become the subject of a very extensive 

 literature. Unfortunately there has been much disagreement 

 about the scientific name of this species, it having been de- 

 scribed independently by many entomologists, so that no less 

 than 23 specific names are cited in synonymy (see the last 

 volume of Howard, Dyar and Knab, The Mosquitoes of North 

 and Central America and the West Indies, now in press). 

 The names most frequently applied have been Culcx fasciatus, 

 C. calopus, C. mosquito, and C. tccniatus. In 1901 the genus 

 Stegomyia was introduced for this species and almost univer- 

 sally adopted, the species now becoming Stegomyia fasciata. 

 A readjustment of generic values caused Dyar and Knab to 

 sink the genus Stegomyia as a synonym of A'cdes} A strict 

 application of the laws of priority made the Fabrician name 

 fasciata (1805) untenable, the name having twice previously 

 been applied to other species in the genus Culex, in 1764 by 

 O. F. Mueller and in 1804 by Meigen.^ This has caused the 

 adoption, by those who adhere to the code of nomenclature,
