In a recent paper, Bauer (1928) has shown that three species of mosquitoes are capable of transmitting experimental yellow fever to Indian monkeys, Macacus rhesus, in addition to the notorious yellow fever mosquito, Aedes aegypti. These are A. (Stegomyia) luteocephalus (Newst.), A. (Aedimorphus) apicoannulatus (Edw.) and Eretmopodites chrysogaster Graham, and are all indigenous to West Africa.

Investigations of other species have continued with the hopes of contributing to a clearer understanding of the feasibility of yellow fever control in that area. Three other Stegomyiae have thus been found to transmit the disease to experimental monkeys, two of which were logically predicted by Bauer (loc. cit.).

Aedes vittatus (Bigot) (= sugens Theo.). This and the following species are included by Patton and Cragg (1913) among the “five common species of Stegomyia.” It is a rapidly maturing and semi-domestic species favoring rain-holding depressions in rocks and masonry for purposes of breeding, but larvae have also been reported as collected from “buckets, roadside puddles and … antiformicas” (Patton and Cragg).
