diffuse posteriorly, are on the center of the dorsum. The pleura are 

 light brown with small patches of dirty, white scales. The legs are 

 black, with the under sides and bases of the femora and a small dot 

 at the knee creamy. The claws are equal and simple on all feet. The 

 abdomen is dark l)rown, all segments with apical white bands, which 

 widen out laterally, till, beneath, it is white with dark brown basal 

 corners. 



Habits. 



This species was met with August 31st, in a rock-bottomed pool, 

 on the Garret mountain, Paterson, in the pupal stage only. Some 

 larvae and pupae of C. pipiens were in the pool at the same time, so 

 it was not known that a new species had been taken until adults began 

 to issue. Two females emerged on the same day of collecting, and 

 September 1st, five others, all females, emerged, each time with 

 pipiens, which, excepting one, were also all females. The last of the 

 brood had been secured, the males having already hatched. 



Uranotcenia sapphirina Osten-Sacken. (The Sapphire-Lined Mos- 

 quito). — No specimens were taken in any stage during the past sea- 

 son. 



Wyeomyia smiihii Coq. (The Pitcher Plant Mosquito). — No effort 

 was made to collect specimens of this species, though it imdoubtedly 

 bred in its usual numbers in the southern portion of the State. 



Note. — The Corethini, formerly a division of the family Culicidce, 

 and embracing the New Jersey genera Sayomyia, Corethra and Core- 

 ihrella, is now given family rank and is called Corethrida'. 



They are distinguished from the Cidicida', or true mosquitoes, by 

 the comparatively short proboscis. 



Sayomyia alhipes Johann. (The White-Legged Corethra). — In the 

 last report a belief was expressed that this species passed the winter 

 in the larval stage. The evidence upon which this belief was based 

 was the collection of a lot of almost full-grown larvae at Paterson, 

 October 3d, none of which showed any further development up to 

 October IGth, when all were placed in alcohol. In the season of 1905 

 a few full-grown larvae and pupa? were taken from a pool on Garret 

 mountain, Paterson, April 18th, and a female emerged April 21st, 

 thus removing all reasonable doubt as to its method of hibernation. 

 It is also probable that they breed continuously throughout the season, 

 as larvie were taken again July and Septemh^'r, and adults bred from 

 thorn the same voar.
