apical lobe possessing one or two strong, gently hooked spines. A small 
patch of setae is present at the apex of the basistyle; these setae are 
very long, reaching to at least the midpoint of the dististyle. The 
mesosome cannot be distinguished from other members of the complex, 
except Culex covagarciat. 
SALIENT CHARACTERS.—Adult female: See table 1. 
Male terminalia: Basistyle conical, slightly longer than twice the 
basal width; clothed with fine setae in addition to the normal, long setal 
pattern; at the apex is a small patch of long setae. Apical lobe of the 
basistyle prominent, undivided, and also clothed with fine setae. Ap- 
pendicles of the apical lobe as follows: rods absent; a group of approxi- 
mately 10 subequal, gently curved setae evenly distributed on the 
lobe; a small tubercle distad of the apical lobe possessing one or two 
strong, gently hooked spines; leaf absent. Dististyle normal. Tenth 
sternite crowned with a sparse tuft of short, pointed spines; basal arm 
rather long, gently curved; three cercal setae present. External 
process gradually expanding distally to the midpoint, then tapering to 
a point; slightly exceeding the ventral cornu in length. Ventral cornu 
long and slender, distinctly separated from the teeth of the median 
process, bent so as to be directed laterally; at the crest of the bend, 
the margin seems to be somewhat granulose. Median process with five 
to 11 strong, sharply pointed, subequal teeth. Basal process short, 
straight, and bluntly rounded. 
Larva: Similar to Culex coronator. Detailed descriptions of the 
immature stages are not available, and individual rearings of speci- 
mens belonging to this species were not examined. 
MATERIAL EXAMINED.—Forty-two male terminalia from areas 
indicated in table 3. 
DistriBuTION.—Probable distribution of this species is plotted on

Culex (Culex) albertot Anduze, 1943a, p. 193. [New synonymy.] 
SysTEMATICcS.—Culezx albertot was described from a single male and 
although the holotype has not been examined, Anduze’s detailed 
original description readily identifies this species with C. ousqua. 
Culex ousqua is distinguished from other members of the complex by 
the appendicles on the apical lobe of the basistyle. The apical lobe is 
divided into a large proximal lobe and a small distal tubercle; a group of 
approximately 10 subequal, gently curved setae are evenly distributed 
on the proximal lobe; four or five subequal, gently curved setae are
