cation given in the record is questionable. 
? 1=important economic species, 2=locally abundant and annoying, principally out of doors; 3=common 
species, not very troublesome; 4=usually rare or of very restricted distribution. 
3 King et al. recorded Culex atratus Theob. from Florida, Boca Chica Key, Dee. 9, 1942. 
4 Exclusive of questionable identifications. 
The following species are listed as being of economic importance: 
Anopheles quadrimaculatus, the common malaria mosquito, transmits malaria 
and is a bad pest otherwise. 
Aedes aegypti, the yellow-fever mosquito, transmits yellow fever and dengue 
fever and is a serious house pest. 
Culex quinquefasciatus, the southern house mosquito, is a serious house pest. 
It transmits bird malaria and is an intermediate host for some of the filaria. 
Aedes sollicitans, the salt-marsh mosquito, is the most important salt-marsh 
species generally in the Eastern and Southern States. 
Aedes taeniorhynchus, the small, black salt-marsh mosquito, is another salt- 
marsh species of economic importance, especially in Florida. 
Psorophora confinnis, the Florida glades mosquito, is an important fresh-water 
species in southern Florida, and is also troublesome in other areas. 
Mansonia perturbans, the common Mansonia, is a severe pest in areas where 
suitable breeding conditions occur. 
(Some of these species may also transmit equine encephalomyelitis or other 
diseases. ) 
The woods mosquitoes, taken collectively, are also important pests 
of man and animals. The principal ones in the Southeast are 
Aedes triseriatus, A. infirmatus, A. atlanticus, A. vexans, Psorophora 
ferox, and P. ciliata. Culex salinarius is important at times, and 
various other species, such as 7. cyanescens, P. varipes, A. canadensis, 
and Mansonia titillans, may become annoying in restricted localities. 
Of the 51 species taken in Florida, 8 are tropical species, and 7 of 
these 8 have not been found elsewhere in the United States. Two 
(Psorophora pygmaea and Anopheles albimanus) have been recorded 
only once each on the extreme southern keys and apparently have 
not become established in the State. Two (Culex bahamensis and C. 
atratus) are known to occur at present only on the Florida Keys. The 
former is probably the same species as that reported several years ago as 
Culex corniger from Knights Key (50). The other 4 species (Wye-
