bers. The species becomes locally abundant in the South, much more 
so during the winter and spring than in the summer. It is of general 
distribution in the Northern, Eastern, and Southern States, but 
becomes rare in southern Florida. The adults usually have a pair, 
sometimes two pairs, of small white dots on the mesonotum (fig. 12, A’). 
The abdomen has conspicuous white bands which are not narrowed 
at the lateral margins. 
Unfortunately, the name terr7tans was changed to designate this 
species after it had been applied for years to the one now known as 
apicalis. Edwards (53) has shown that the synonymy is very doubt- 
ful, and the writers agree with him in the desirability of restoring the 
name restuans, so that there will be no confusion as to the species 
meant. 
CULEX APICALIS Adams 
(Syn., C. territans Dyar (not Walk.) in part, C. testaceus Dyar (not V. d. W.), 
C. saxatilis Gros., etc.) 
Culex apicalis has a wide distribution and is found breeding in 
grassy pools and swampy places containing aquatic vegetation. 
The larvae are fairly common, but the adults apparently do not bite 
man. As they have been observed feeding on frogs, they probably 
live on cold-blooded animals. 
The adults are recognized by the presence of narrow white bands, 
which widen laterally, on the posterior margins of the abdominal 
segments. The name apzcalis refers to this character. 
CULEX TARSALIS Cog. 
The writers have one collection of this banded-legged Culex from 
Louisiana (Mound, October 13, 1918, D. L. Van Dine). The larvae 
were taken in a clay borrow pit with Anopheles punctipennis, but 
were not obtained again, although many collections were made in 
the same locality during the following 10 or 15 years. It has also 
been reported from Arkansas (47, 85), from Orleans Parish (47) and 
Lake Charles, La. (75), and from Florida and Tennessee (table 1). 
This species is very common in the Western States. 
CULEX BAHAMENSIS D. and K. 
(Syn., 0. corniger Dyar (not Theob.) ) 
This is a tropical species that has recently been collected by Fisk 
(55) in several breeding places at Key West, Fla., including an un- 
derground cistern containing brackish water. The writers have also 
identified a male of this species collected on Elliott Key in the spring 
of 1940 by F. H. Stutz. It now seems probable that the specimens 
previously recorded by Dyar (50) as Culex corniger Theob., from 
Knights Key, Fla., were the same species, since the identification was 
based on a collection of females only and the two species are not 
easily distinguished in this stage. 
The larva of Culex bahamensis has only two anal gills, instead of 
the normal four, and they are thick and bulbous. The adult female 
has narrow white rings on the tarsi, which occur on both sides of the 
joints on the hind tarsal segments.
