A total of 23 named species, known in all stages, and 4 unnamed forms, known by 1 or more females, is treated. In all, 22,235 specimens, 4,164 males, 4,967 females, 7,542 larvae, 5,562 pupae and 2,424 individual rearings (1,497 larval, 767 pupal, 160 incomplete) have been examined. The methods of study and presentation, as well as the terminology and ab- breviations, follow, in general, Belkin (1962); a few additional terms for the meso- scutal markings and details of the genitalia follow Berlin (1969) and Schick (1970a), respectively. I am indebted to John N. Belkin for reading the manuscript and suggesting certain improvements; Harold C. Chapman, George B. Craig, Jr., Pedro Galindo, Kenneth L. Knight, Lewis T. Nielsen, George F. O'Meara, L.L. Pechuman, John F. Reinert, Paul L. Rice, Alan Stone, Floyd G. Werner, and Michael J. Zavortink for loans of museum specimens or gifts of live mosquitoes; Willis W. Wirth for information on the type of Finlaya nigra; Abdiel J. Adames, J. Hal Arnell, Lewis T. Nielsen and Robert X. Schick for stimulating discussions; Sandra J. Heinemann and William A. Powder for help in the preparation and rearing of specimens; Sharon Burmeister, L. Margaret Kowalczyk and Nancy L. Martsch for prepara- tion of many of the preliminary drawings and L. Margaret Kowalczyk for prep- aration of all of the final illustrations; Claire M. Price for typing a portion of the preliminary draft; and, finally, Caryle Stallard for typing the remainder of the preliminary draft, providing editorial assistance and preparing the text copy for lithoprinting. SYSTEMATICS I am removing all New World Aedes that have been placed in the subgenus Finlaya from that subgenus and assigning them to other subgenera or genera, as follows: the Triseriatus, Zoosophus, Kompi and Knabi Groups treated in the pres- ent paper and the Terrens Group treated by Schick (1970a,b) are placed into the subgenus Protomacleaya of Aedes; ramirezi and mediovittatus are placed into the monotypic subgenera Aztecaedes and Gymnometopa of Aedes, respectively; the Atropalpus and Fluviatilis Groups are placed into the subgenus Ochlerotatus of Aedes; scutellalbum and upatensis
