NO. 3557 SUBGENUS CULEX—BRAM 43 
larger than the lateral teeth; the sub-basal lateral teeth longer than 
the other lateral teeth. Thorax and abdomen spiculate. Comb with 
numerous scales in a patch; each scale rounded apically and fringed 
with subequal spinules. Siphonal index more than 8.0 ; Siphon slender 
and only slightly tapered; seven to nine pairs of two to four branched 
siphonal tufts inserted in a straight line. Pecten with nine to 12 
teeth on the basal third of the siphon; each tooth with three to five 
coarse barbs on one side. Anal segment completely ringed by the 
saddle; gills shorter than the saddle. 
MATERIAL EXAMINED.—Three adult males and associated terminalia 
from Argentina, two from Brazil, two from Ecuador, two from Puerto 
Rico, one from Venezuela, and one from Texas. The lectotype male 
from Panama was also studied. 
Distrisution.—Reported from Panama (the type locality), Costa 
Rica, Mexico, Texas, Puerto Rico, J amaica, Lesser Antilles, Venezuela, 
Colombia, Ecuador, Brazil, and a questionable record from Bolivia. 
The author has seen specimens in the U.S. National Museum collection 
from Concepcidén and Medinas, Tucuman, Argentina.

SYSTEMATICS.—Culex corniger is distinctive from other members of 
the subgenus having only one accessory seta next to the leaf on the 
apical lobe of the basistyle by possessing a short, pointed, distinctive 
external process. 
SALIENT CHARACTERS.—Adult female: See table 1. 
Adult male: Basistyle tubular, two and a half times as long as the 
basal width; clothed with fine setae in addition to 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 narrow, straight, and pointed; median rod robust, longer 
than basal rod, and prominently hooked at the apex; apical rod similar 
in size and shape to the basal rod; leaf short and truncate, with some 
minute, basal, longitudinal striations; accessory seta long and gently 
curved. Dististyle normal. Tenth sternite crowned with a dense 
tuft of short, pointed spines; basal arm moderate in length, strongly 
curved at the distal end; two cercal setae present. External process 
narrow, straight, and sharply pointed; not reaching the ventral cornu.
