same place other pnp^ were taken on the 21st, yielding adults 

 on the 22nd. May 26th, larv?e and pupae were taken by Mr. 

 Dickerson in the Black River Swamp in M'orris County and a 

 single example of this species was identified among a lot of 

 canadensis. 



There are no records of later captures in any stage and it is 

 fair to conclude that there are no late broods. 



Mr. Brakeley classes this among the local breeders ; that is, a 

 species which he can count upon finding every year in about the 

 same places ; but which does not occur in all bodies of water even 

 under similar conditions. 



URANOT^NIA SAPPHIRINA, OSTEN-SACKEN. 



The Sapphire-lined Mosquito. • > 



A small dark brown mosquito with the beak and legs unhanded, 

 though there is a large white dot at apices of the femora and 

 tibiae. The thorax is marked with metallic blue spots and there 

 is a narrow line of the same color down the center of the dorsal 

 surface. The abdomen is narrowly banded at the apex of some of 

 the segments. The wings are unspotted. 



Description of the Adult. 



This is a very small mosquito, measuring 2.5-3 nim.,==. 10-. 12 

 of an inch in length, with a beak almost two-thirds the length 

 of the body. The head is black, with a patch of metallic blue 

 scales in the angle formed by the eyes, and often patches of 

 similar ones on the posterior edge of the eyes, which join the 

 anterior patch ; the palpi (fig. 66, 2) are alike in both sexes, short 

 and two jointed, the apical joint with long bristles; the proboscis 

 is brownish, hairy and swollen at the tip. The antennae in the 

 female are pilose, brown in color, with the large basal joint 

 yellow ; in the male they are plumose, dark brown, with paler 

 plumes. 



The thorax is brown and has many long, black, curved bristles; 

 a median narrow line of metallic blue scales extends the whole 

 length of the mesonotum, not quite reaching the anterior margin 

 and a short, blue, curved line is slightly anterior of each wing. 

 The patagia are wholly covered with blue scales and appear as 

 lobes from above. The pleura are light brown, with two small 

 patches of blue scales, which are very often connected. The legs
