AQUATIC INSECTS IN NEW YOKK STATE 409 



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. m a c u 1 i p e n n i s . Trolonged 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 

 arrangement 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 

 lateral) are branched. The anus is at the extremit}^ 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.ll]
