The major portion of material examined during the course of this 
study is housed in the U.S. National Museum (USNM). Additional 
specimens from collections in the following institutions were also 
consulted: Trinidad Regional Virus Laboratory, Trinidad (TRVL); 
Instituut Voor Tropische Hygiene en Geographische Pathologie, 
Amsterdam (ITHGP); Instituto National de Microbiologia, Buenos 
Aires (INM); Servigo De Erradicagio da Malaria e Profilaxia da 
Doenca de chagas, SAo Paulo (SEMPDC); Division de Endemias 
Rurales, Maracay (DER); Universidade de Sio Paulo, Sao Paulo 
(USP); Centro Ecuatoriano de Investigaciones Entomologicas (lo- 
cated in the USNM); and Instituto de Salubridad y Enfermedades 
Tropicales, Mexico, D. F. (SET). 
Since this manuscript was originally submitted for publication, 
Forattini (1965) has published a monograph of the culicine mosquitoes 
of the new world utilizing, in part and with the author’s permission, 
the classification of Bram (1964). Unfortunately, Dr. Forattini was 
not aware that the present manuscript had not yet been published in 
accordance with the International Code of Zoological Nomenclature 
and, therefore, attributed Culex alani, O. bickleyi, C. covagarciai, and 
C. oswaldoi to Bram (1964). Since Forattini (1965) was the first 
author to publish these species in accordance with the Code, the names 
must be credited to him. However, since Forattini saw no specimens 
and did not designate holotypes or type localities for these species, 
the original material upon which the species were based by Bram 
(1964) should be recognized as the type series for the species. Simi- 
larly, synonymy listed as new in this publication was actually first 
published by Forattini (1965), but reasons for proposing the synonymy 
are included in this paper. 
New World synonymy is listed under each species. Complete 
references may be found in Stone et al. (1959) and Stone (1961, 1963). | 
Zoogeography 
Little is known about the zoogeography of the family Culicidae. | 
This is due mainly to reasons enumerated by Bates (1949), who
