of from 14 to 22 scales, as shown at figure 6. The individual 

 scales are shown at figure 7, and are ovate, the sides fringed 

 with spines which lengthen toward the tip, so that at this 

 point there is a long straight barb. 



The anal siphon (fig. 6) is short and chunky ; very dark 

 brown, almost black, in color. It has the usual double series 

 of spines, and these are of moderate length, taper rapidly to a 

 long acute tip, and tend to have short teeth near the base on 

 the inner side. 



The anal gills are short, without obvious tracheae, and the 

 species has the normal Culex habit of getting air through the 

 siphon only. 



Culex discolor. 



This is a yellowish-brown mosquito, of moderate size, the 

 body mottled and variegated with brown, legs and beak banded, 

 wings spotted. This combination occurs in no other New 

 Jersey species, and makes it an easily recognizable form. 



Larvae were collected by Mr. W. P. Seal, at Delair, June 

 1 8, 1903, and received at the laboratory June 2oth. They 

 were recognized as new to us, attracting attention, first, by 

 their unusually prominent, white antennae ; second, by the 

 very long anal gills ; third, by the habit of resting on the bot- 

 tom, back down, antennae pointing upward, and mouth - 

 brushes kept in constant motion. Pupae were formed June 

 23d and 24th, and on the 27th and 28th adults emerged, a 

 pupal period of four days. A second lot was received July 

 24th, but they were small, did not do well, and only one 

 female adult was secured August 8th. Mr. Seal states that 

 these larvae are rare, and he noted their habit of remaining 

 below the surface and feeding at or near the bottom. A sin- 

 gle larva was also received from Mr. J. T. Brakeley, taken at 

 L/ahaway, Ocean County. 



The larva (Plate x, fig. i) is from 7 to 8 mm. in length, 

 including the anal siphon, and is yellowish brown in color 

 throughout. The head is almost as large as the thorax, widest 

 at the eyes, a little excavated before the antenn , front 

 square. The antennae (Plate x, fig. 4) are white, almost 

 as long as the head, thickest centrally, with an out- and an
