punetipennis or quadrimaculatus. A study of the chaetotaxy of the 
four instars has been published by Hurlbut (87). 
ANOPHELES BARBERI Cog. 
The larvae of this mosquito are found principally in tree holes, 
although the writers once took them in wooden tubs at Mound, La. 
The adult is very small, with unspotted wings, and is rarely encoun- 
tered. It has been proved susceptible to infection with malaria para- 
sites but is of doubtful importance in malaria transmission (140). 
Thibault (742) in Arkansas noted that it enters dwellings readily and 
is a persistent biter, although easily disturbed. 
The species has been recorded from various places throughout the 
East and South from Ithaca, N. Y., to Houston, Tex. With recent 
records from Reelfoot Lake (57) and Norris, Tenn. (736) and from 
several counties in Georgia (notes from Justin Andrews), it has now 
been reported from all the Southeastern States. 
ANOPHELES ALBIMANUS Wied. 
(Syn., A. albipes Theob.) 
This species is the only anopheline included here in which the tarsi 
are white-banded. It is a tropical species, of much importance as a 
vector of malaria in tropical America. It was introduced into Key 
West, Fla., in 1904, and apparently developed one brood there. ac- 
cording to the records of its discoverer, George N. MacDonell. For- 
tunately it did not become established and has not since been reported 
from that locality. At the present time the only place in the United 
States where it is knewn to occur is the lower Rio Grande Valley, 
Tex. The distribution of this species and the possibilities of its be- 
coming established in southern Florida and along the Gulf coast 
have been discussed by King (94). 
Genus CuLEx Linnaeus 
(Syn., in part, Melanoconion Theob., Mochlostyraz D. and K., Neoculex Dyar, 
Choeroporpa Dyar) 
The mosquitoes of this genus breed in more or less permanent col- 
lections of water. The eggs are laid on the surface of the water 
in rafts of a hundred or more (fig. 3, 4), and they hatch within 2 
or 3 days at summer temperatures. Breeding is continuous during 
warm weather and even through the winter in the warmer parts 
of Florida and the Gulf coast. Elsewhere the winter is passed in 
hibernation as adult females. 
In identifying some of their collections of Culex, particularly those 
taken in light traps, the writers have found it convenient to use 
subgeneric names, since the specimens frequently are in poor condition 
or difficult otherwise to identify as to species. For the small species 
of Culex Dyar’s subgeneric name Mochlostyrax has been employed 
previously, but Edwards (53) has reclassified them on larval charac- 
ters that place two of the three local species in Melanoconion. Since 
the differences are of a minor nature and it is difficult to define the 
two subgenera by either classification, the writers are of the opinion 
that only the earlier name J/elanoconion need be retained. The 11
