especially in beds of Chara. Elsewhere they have been collected in 
salt-marsh pools containing flotage, algae, and grasses. 
The larval characters most nearly resemble those of Anopheles 
punctipennis, from which they can usually be distinguished by the 
fact that the leaflets of the palmate hairs on segments 3 and 7 are 
slender, mostly with smooth margins and smaller than those on seg- 
ments 4 to 6. In pwunctipennis the palmate leaflets are all about 
equally broad and usually notched near the tip. Many adult speci- 
mens appear to be indistinguishable from those of typical erucians, 
but about half of the females examined have the stem of vein 5 com- 
pletely or mostly white-scaled, whereas it is entirely dark-scaled in 
crucians. 
ANOPHELES GEORGIANUS King 
(Syn., A. crucians var. georgianus King) 
This species was first collected by Bellamy (77) in 1937 from fresh- 
water breeding places in southern Georgia and was described by 
King (95) as a variety of Anopheles crucians. The spots on the wings 
appear to be more contrasting than in crucians, but no positive charac- 
ters have been found for separating the adults. The larva, however, 
is unusual in that only three pairs of functional palmate hairs are 
present (on segments 4 to 6), whereas crucians and all the other species 
of Anopheles have at least five. The larvae are further distinguished 
from bradleyi by having a larger number of branches in the antepal- 
mate hairs of segments 4 and 5, and from crucians by the lack of devel- 
opment of the anterior submedian hairs (hair 0) on these and other 
segments. In the pupal stage the corresponding hair is usually un- 
branched in georgianus but with three to five branches in crucians. 
In bradleyi the branching is more irregular. Slight differences in the 
claspette spines of the male genitalia were described by King (95), 
with crucians intermediate in these characters. 
Anopheles georgianus has been collected by Bellamy (77) in Brooks, 
Sumter, Terrell, and Thomas Counties, Ga. A single larva was 
identified from a collection of crucians made by G. H. Bradley in ponds 
near Hinesville, Ga., in March 1941. It has since been reported from 
all the Southeastern States except Tennessee and Arkansas. Its 
typical habitat appears to be in seepage areas at the head of small 
streams, and the larvae were usually found in pure culture or with a 
small proportion of crucians. Scattered larvae were also reported 
from other types of ponds. 
ANOPHELES PUNCTIPENNIS (Say) 
(Syn., Culex hyemalis (Fitch), Anopheles perplexens Ludl.) 
Anopheles punctipennis ranges from the Atlantic to the Pacific 
coast and has a variety of breeding places. In the South it appears 
to prefer the margins of flowing streams, probably because of the 
lower temperature of the water. Throughout the southern range it 
occurs much more commonly late in the fall and early in the spring 
than in the summer (7, 79). At Mound, where it was never abundant, 
it disappeared almost entirely during the warm months. In that 
vicinity pure cultures of the larvae were sometimes taken in the 
fall in small clay borrow pits or pools free of vegetation. Asa rule 
the species is rare in central and southern Florida. The writers have 
found the adults in some numbers at Rock Springs, Orange County,
