apparently chitinized plate, which may be folded over them, 
flaplike; on each side of them is a conical papilla with a few 
bristles at the apex. These are not figured by Nuttall though . 
figured by Meinert for C. maculipennis. Prolonged back- | 
ward are two lobes (somewhat pressed_apart in the figure), and 
between these is an elongate, flattened, checkered plate forming 
the floor of the area. On the ventral surface of each posterior 
lobe are a branched hair and a few bristles. On either side of 
this structure is a comb, its teeth projecting caudad. Each 
comb has about seven long teeth, and between each of these are 
from one to four shorter ones. The cylindric ninth segment, 
when the animal lies horizontal, its dorsal surface uppermost, 
is suspended obliquely below the breathing apparatus, its dorsal 
surface covered with a chitinized plate or saddle. From its 
ventral surface, attached to a keellike process, is a fanlike 
airangement consisting of two rows, each with nine branched 
hairs. On the dorsal surface are four hairs, the two anterior 
‘ones are feathered, the two posterior (and also a little more 
_ijateral) are branched. The anus is at the extremity of the seg- 
ment, and surrounded by the four white papillae or blood gills. 
Pupa. Resembles that of the other Culicidae. “When 
viewed sidewise, the pupa of Anopheles presents a compara- 
tively smooth outline, but in Culex the edge where each tergum 
joins posteriorly the soft integument which unites it with the 
succeeding tergum stands out as a ridge, and the dorsal out- 
line presents a series of salient angles” [Nuttall & Shipley]. 
*“ Respiratory trumpets are not so broad terminally in Culex as 
in Anopheles” [Howard]. [pl.42, fig.11]
