NO. 3557 SUBGENUS CULEX—BRAM 69 
with about 17 teeth; the apical tooth considerably broader and longer 
than the lateral teeth. Comb with numerous narrow scales in a patch. 
Siphonal index about 6.0; three double or triple siphonal tufts beyond 
the pecten. Pecten with numerous teeth on the basal third of the 
siphon. Anal segment completely ringed by the saddle. 
MATERIAL EXAMINED.—One adult male and associated terminalia 
from Colombia, four from Costa Rica, nine from Panama, 13 from 
Venezuela, and three from Trinidad. 
DistriBuTION.—This species has been reported from the Lesser 
Antilles, Cuba, Trinidad, Mexico, Costa Rica, Panama, Colombia, and 
Venezuela.

Systematics.—In the male terminalia this species appears to be 
close to Culex peus, C. stenolepis, and C. thriambus; however, the 
appendicles of the apical lobe of the basistyle and the distinctive 
ventral cornu are diagnostic. 
SALIENT CHARACTERS.—Adult female: See table 1. 
Male terminalia: Basistyle conical, slightly longer than twice the 
basal width; clothed with fine spicules in addition to the normal, 
long setal pattern. Apical lobe of the basistyle rather flattened, 
undivided, and also clothed with fine spicules. Appendicles of the 
apical lobe as follows: three fine, subequal, gently curved rods; 
a narrow, bluntly rounded leaf which exhibits minute longitudinal 
striations; two accessory setae, one straight the other prominently 
hooked. Dististyle normal. Tenth sternite crowned with a dense 
tuft of short, pointed spines; basal arm moderate in length, gently 
curved; cercal setae absent. External process very broad, tapering 
to a point, and curved so as to be directed laterally; not reaching 
the ventral cornu. Ventral cornu large, rounded and rugulose. 
Median process with five to seven sharply pointed, distinctly sepa- 
rated teeth. Basal process not a distinct arm, but represented by 
a round bulge of the mesosome. 
Larva: Antennal tuft located in a constriction near the outer 
fourth; antennal shaft spiculate basally. Postclypeal head hair 
4 short, single; upper and lower frontal head hairs 5 and 6 long, 
triple; preantennal head hair 7 long, multiple. Mentum with approxi- 
mately 17 teeth; the apical tooth broader and longer than the lateral 
teeth. Thorax sparsely spiculate. Comb with numerous scales in 
a patch; each scale long, narrow, with apex expanded and fringed 
with subequal spinules. Siphonal index 3.0 to 3.5; four pairs of
