Culex serratus Theo. 



PI. 44, 52, fig. 4, 4 respectively 



This species is a moderate sized, well marked form, and may.be 

 recognized by the prominent silvery white stripe in the middle of 

 the thorax. 



Description. The larva has a dark brown head, somewhat flat- 

 tened, tapering anteriorly. The antennae are darker at the tip, 

 not quite half the length of the head, and are terminated by four 

 articulated spines, and the tuft of hair arises near the middle. 

 The triangular labial plate has 35 fine teeth. The air tube is 

 about twice as long as wide, a little dilated before the middle, 

 with posterior pecten, each consisting of seven to nine spines 

 minutely toothed near the middle and with a conspicuous terminal 

 tuft. The comb is composed of five somewhat spatulate scales 

 arranged in a short curved line. 



Distribution. A larva of this species was received in September 

 from J. E. de la Torre Buen'o who took it in a fresh-water pool on 

 Staten Island. This species has been recorded by Theobald, from 

 several South American localities, and Dr Smith states that it 

 ranges the full length of the state of New Jersey. 



Life history and habits. Larvae and pupae of this species were 

 taken by Dr Smith in a low swampy woodland in New Jersey, 

 July 29, and adults began to appear the next day. A few larvae 

 were also taken in early September, and adults were met with 

 near dried up pools the middle of the month. These pools became 

 filled with water and produced larvae and pupae Sep. 30, and 

 adults emerged early in October. The species appears to be a 

 woodland form, since Dr Smith states that he has never received 

 it in miscellaneous lots collected near and in towns and villages. 



Culex dupreei Coq. 



PI. 46, 53, fig. 3, 6 respectively 



This small mosquito, originally described from Louisiana, 

 ranges in color from grayish brown to nearly black. There is on 

 the dorsum of the thorax a silvery white stripe with diffuse edges, 

 which is continued on the head occupying most of the space be- 

 tween the eyes. This species resembles a small C. serratus,
