The dangerous vector of malaria, Anopheles darlingi Root, has been found in three places in Central America, in British Honduras, in Guatemala, and in Spanish Honduras. It has not hitherto been known north of Venezuela, in South America.
Severe malaria is known to be present in British Honduras and in Guatemala, and this may be associated with the presence of A. darlingi.
The species has probably been present for at least 15 years in Spanish Honduras.
The present status of A. darlingi in Central America is discussed.
Notes on the literature, showing the very high natural infection rates of this species in South America, are given.
Suggestions as to future investigations are outlined.
