SysTeMATiIcs.—This species may be distinguished from Culex 
brethest by the number of appendicles on the apical lobe of the basistyle. 
It is distinguished from C. acharistus by lacking annulations on the 
dististyle and from C. laticlasper by the appendicles of the apical lobe 
of the basistyle and by the median plate of the mesosome. 
SALIENT CHARACTERS.—Adult female: See table 1. 
Male terminalia: Basistyle conical, about two and a half times as 
long as the basal width; clothed with fine spicules in addition to the 
normal, long setal pattern. Apical lobe of the basistyle prominent, 
undivided, and also clothed with fine spicules. Appendicles of the 
apical lobe as follows: basal rod narrow, terminating in a small hook; 
median and apical rods subequal, broader and longer than the basal 
rod, and terminating in a prominent hook; leaf small, not as long as 
the rods, and obovate; two accessory setae present, both fine, gently 
curved and longer than the leaf. Dististyle normal. Tenth sternite 
crowned with a dense tuft of short, pointed spines; basal arm moderate 
in length and curved; one or two cercal setae present. External 
process very broad, somewhat twisted, and tapering to a point. 
Median process without teeth. Basal process absent. 
Larva: Antennal tuft inserted near the middle of the antennal shaft, 
antennal shaft spiculate, slightly narrowed and darker beyond the 
antennal tuft. Postclypeal head hair 4 short, double or triple; frontal 
head hairs 5, 6, and 7 long, multiple, and barbed. Mentum broad, 
with about 20 very long, subequal, bluntly rounded teeth. Body 
glabrous. Comb with many scales in a patch; each scale rounded and 
fringed apically with subequal spinules. Siphonal index 4.0 to 4.5; 
siphonal tufts represented by three pairs of long, single hairs irregu- 
larly placed on the siphon, and a pair of small, subapical, two or three 
branched tufts inserted beyond the pecten. Pecten with 12 to 20 
teeth on the basal third of the siphon; each tooth with one to five 
coarse barbs on one side. Anal segment completely ringed by the 
saddle, which is spiculate on the dorso-apical surface. 
MaTERIAL EXAMINED.—A series of 25 adult males and associated 
terminalia from the United States.
