County until August 22, when there was a slight invasion in 

 the northeastern section of Newark. In Hudson County it 

 was the predominating species, as very little work had been 

 done to check the breeding. In Union County pipicns was re- 

 duced considerably by the continued oiling and filling in of the 

 breeding places and not many individuals were noticed 

 throughout the season. 



Anopheles maculipennis was very abundant throughout the 

 State, more so than in previous years, and larvae could be 

 found in the eddies of all brooks, in among the grass along 

 the edges of brooks, and in almost any grassy pool scores of 

 larvae could be found. The most prolific place that was dis- 

 covered for this species was near White City in Mercer 

 County. The swamps in that section were alive with them. 



Anopheles punctipennis was very abundant throughout the 

 State and larvae were found almost anywhere until November. 

 The most prolific place for this species was found near Prince- 

 ton. 



Anopheles crucians was quite rare throughout the entire 

 season and only odd specimens, all in the larvae stage, were 

 noticed and these were found on the saltmarsh along Barne- 

 gat Bay. 



Psorophora ciliata was apparently rare throughout the sea- 

 son. Few larvae were noticed and not many adults were seen 

 anywhere. The prolific breeding places for this species in 

 Essex County have been eliminated. 



Aedes sayi was plentiful in the Great Piece Meadows 

 (Essex County) during the latter part of August. As this is 

 one of the most ferocious species in the State it made life 

 miserable for both man and beast in that region. 



Aedes jamaicensis was very rare and no records were made 

 at all. 



Aedes cant at or was not as abundant in the northern part of 

 the State as in 1911 ; in the southern portion, however, it was 

 very plentiful and in exceedingly large specimens. The first 

 brood hatched early in May and they held on for nearly six 

 weeks, and no more hatching took place until early in Sep- 

 tember, when they appeared in association with sollicitans.
