NO. 3557 SUBGENUS CULEX—BRAM 101 
Siphonal index about 4.0; six multiple siphonal tufts on the siphon, 
the basal tuft inserted within the pecten. Pecten with about 13 teeth 
on the basal third of the siphon, the apical tooth removed from the 
other pecten teeth; each tooth with coarse barbs on one side. Anal 
segment completely ringed by the saddle, which is spiculate distally. 
MATERIAL EXAMINED.—Three adult males and associated terminalia 
from Puerto Rico and one from Jamaica. 
DIstTRIBUTION.—Reported from Jamaica (the type locality), His- 
paniola, Puerto Rico, the Lesser Antilles, and Venezuela.

Systrematics.—This species demonstrates close affinity with Culex 
nigripalpus but is distinctive in the arrangement and conformation 
of the appendicles on the apical lobe of the basistyle. 
SALIENT CHARACTERS.—Adult female: See table 1. 
Male terminalia: Basistyle conical, about two and a half times 
longer than the basal width; clothed with fine spicules in addition 
to the normal, long setal pattern. Apical lobe of the basistyle promi- 
nent in the area of the rods, but somewhat flattened in the area of 
the leaf and accessory setae; also clothed with fine spicules. Appen- 
dicles of the apical lobe as follows: basal rod straight, strong, and 
pointed; median rod broader and longer than the basal rod, termi- 
nating in a gentle hook; apical rod longer and broader than the median 
rod, also terminating in a gentle hook; two subequal, strong, straight, 
pointed accessory setae located between the apical rod and the leaf; 
leaf rather narrow and truncate, about as long as the accessory setae. 
Dististyle normal. Tenth sternite crowned with a dense tuft of short, 
pointed spines apically and six to nine spatulate, scalelike spines on 
the lateral outer margins; basal arm short and gently curved; about 
six cercal setae present in a compact group. External process some- 
what curved and bluntly rounded; not reaching the ventral cornu 
in length. Ventral cornu distinct from the teeth of the median 
process, truncate and serrate. Median process with about six 
distinct, sharply pointed teeth. Basal process reduced to a bulbous 
expansion of the mesosome; not distinct. 
Larva: Antennal tuft located in a constriction near the outer third; 
antennal shaft spiculate basally. Postclypeal head hair 4 short, 
single; upper and lower frontal head hairs 5 and 6 three or four 
branched, long, barbed; preantennal head hair 7 multiple, long, and 
barbed. Mentum with about 17 teeth, the apical tooth broader 
and larger than the lateral teeth. Thorax finely spiculate, abdomen 
glabrous. Comb with numerous scales in a patch; each scale rounded
