REPORT ON MOSQUITOES. 227 



Pupation began May 3d, and a male squamiger emerged May 

 8th, though possibly not from the first pupa. Additional collec- 

 tions were made May i6th, mostly pupae and mostly canadensis; 

 but in two days fourteen specimens, nearly equally divided as to 

 sex, were bred out. Though this territory was collected over 

 many times later in the season and several other species were 

 found, no further trace of squamiger appeared. It is probable, 

 therefore, that only one brood occurs, and that very early in the 

 season. Nothing is known of the egg-laying habits nor of the 

 method of hibernation, but from their early date of appearance 

 and their constant association with canadensis, it is probable that 

 the eggs winter like and with those of its associate. 



CULEX NIVKITARSIS, COO. 



The Snomy Foot Mosquito. 



This is a rather small brown mosquito with pale brown legs ; 

 the first two joints of the tarsi in the fore and mid legs are nar- 

 rowly white banded at each end; the remaining joints of fore 

 legs without bands; the remaining ones of the middle legs nar- 

 rowly banded at the bases. In the hind legs the tarsi are wholly 

 white, save for a faint brown band in the center of the three 

 mid joints. The beak is unhanded, the wings unspotted, the 

 thorax is evenly brown, while the abdomen is narrowly white 

 banded in the female, broadly banded in the male, becoming very 

 wide toward the sides. 



Description of the Adult. 



Owing to insufiicient material for dissecting purposes, none 

 of the details could be drawn, and j\Ir. D. W. Coquillett's de- 

 scription is quoted in full : 



"Female : black, thorax and scutellum brown, first antennal 

 joint, halteres, coxae, femora and tibiae yellow, the hind tarsi

 middle joints. Scales of palpi brown, those of the basal portion 

 yellow, on the apex white; scales of upper part of occiput golden
