upon which is located a sphincter-form ring; teeth absent. Basal

antennal shaft spiculate basally. Postclypeal head hair 4 short, 
single; upper frontal head hair 5 long, multiple; lower frontal head 
hair 6 long, triple; preantennal head hair 7 long, multiple. Mentum

about 8.0; eight pairs of two to four branched siphonal tufts present 
on the siphon. Pecten with eight to 12 teeth on the basal fourth of 
the siphon; the distal tooth is considerably removed from the other 
teeth; each tooth is long, thin and with numerous barbs on one side.

SystemMatics.—This is one of the three species characterized by 
possessing two distinct leaves on the apical lobe of the basistyle. It 
is distinct from Culex diplophyllum by not having annulations on the 
apical third of the dististyle. It differs from C. lahillei by possessing 
a prominent enlargement at the apex of the dististyle. 
SALIENT CHARACTERS.— Adult female: See table 1. 
Male terminalia: Basistyle conical, about twice as long as the basal 
width; clothed with fine setae in addition to the normal, long, setal 
pattern. Apical lobe of the basistyle prominent, undivided, and 
clothed with fine setae. Appendicles of the apical lobe as follows: 
basal rod strong, gently hooked at the apex; median rod broader and 
longer than the basal rod, and with a prominent distal hook; apical rod 
longer than the median rod and prominently hooked; two leaves 
present, the proximal leaf broad and tapering to an apical point, the 
distal leaf more narrow, equally as long, and also tapering to a point; 
no accessory setae present. Dististyle normal but distinctly enlarged 
at the apex. Tenth sternite crowned with a dense tuft of short, 
pointed spines; basal arm moderate in length, gently curved; about 
three cercal setae present. External process gradually tapering to a 
point, slightly exceeding the ventral cornu in length. Ventral cornu 
dentiform, slightly larger than, and close to the teeth of the median 
process. Median process with three to five distinctly separated teeth. 
Basal process short, straight, and bluntly rounded.
