198 AGRICULTURAL EXPERIMENT STATION. 



the siphonal tuft is exceptional!}^ large and consists of from six 

 lo eight hairs. There are from 5 to 8 spines in each lateral row, 

 all with two or three long teeth (fig. 10). The ninth segment is 

 transversely oblong, widest at the dorsal part, and with the usual 

 double tuft of hairs. The barred area of the ventral part is 

 small and has only three or four tufts of long hair and a row of 

 very short tufts. The anal gills are long, twice as long as the 

 siphon, and provided with obvious tracheae. 



Habits of the Larva. 



This larva has been sent in only by Mr. William P. Seal, of 

 Delair, N. J., in small numbers. The first lot was collected June 

 18, 1903, received at the laboratory June 20th. They were at 

 once 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 bottom, back 

 down, antennas pointing upward and mouth brushes kept in con- 

 stant 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 the larvae are rare, and he noted their habit 

 of remaining below the surface and feeding at or near the 

 bottom. 



This species is so far removed in general character of both 

 larva and adult from the other species of C^ile.v that it should 

 not really remain associated with them. The bottom feeding 

 habits of the larvae are further characteristic and far removed 

 from those of the more typical species. 



CULEX SOLLICITANS^ WALK. 



The JVhite-handed Salt Marsh Mosquito. 



The distinctive characters of this species are the broadly white 

 banded tarsi, the white banded beak and the yellowish white 

 bands at the base of the abdominal segments, crossed longitudi- 

 nally in the center by a broad continuous line of the same color. 

 The thorax is golden brown with the sides silvery white. This 

 combination of characters occurs in no other New Jersey species 

 and renders it recognizable at a glance.
