NO. 3557 SUBGENUS CULEX—BRAM 87 
undivided, and also clothed with fine spicules. Appendicles of the 
apical lobe as follows: rods absent; a group of about seven long, 
pointed, gently curved setae evenly distributed; leaf absent. Disti- 
style normal. Tenth sternite crowned with a sparse tuft of short, 
pointed spines; basal arm moderate in length, strongly curved; two 
or three cercal setae present. External process gradually tapering 
to a blunt point; considerably exceeding the ventral cornu in length. 
Ventral cornu dentiform, but very large and distinctly separated 
from the teeth of the median process. Median process with about 
four, small, sharply pointed, subequal teeth. Basal process moderate 
in size, tapering to a blunt point, and directed posterolaterally. 
Larva: Unknown. 
Hotortypr.—An adult male and associated slide mounted terminalia

MacCreary, Colr.; reared quarry hole; Serial No. 12; RB62 290. 
USNM 67550; deposited in the U.S. National Museum. I take 
great pleasure in naming this species in honor of Dr. Oswaldo P. 
Forattini.

SYSTEMATICS.—This species is similar to Culex chidesteri and C. 
interrogator but may be distinguished by the arrangement and number 
of appendicles on the apical lobe of the basistyle and by the confor- 
mation of the structures of the mesosome. 
SALIENT CHARACTERS.—Adult female: See table 1. 
Male terminalia: Basistyle conical, slightly longer than twice the 
basal width; clothed with minute spicules in addition to the normal, 
long setal pattern. Apical lobe of the basistyle prominent, undivided, 
and also clothed with minute spicules. Appendicles of the apical 
lobe as follows: basal rod strong, straight, and bluntly rounded; 
median rod longer and broader than basal rod and terminating in a 
prominent hook; apical rod longer than, but not as broad as median 
rod, terminating in a gentle hook; leaf small, pointed distally, and 
possessing distinct longitudinal striations; two accessory setae present, 
one prominently hooked, the other gently curved and pointed. Disti- 
style normal. Tenth sternite crowned with a dense tuft of short,
