Culex canaden^i^-, whose hirva^. in early spring usually crowd the 

 AvooJlaiid }X)ols, was conspicuous l)v its almost eutire absence durinu' 

 the past year. It was present in some nniulicrs in a few places, 

 but as compared Avith foruier j-ears this wa,s entirely insigiiiticant. 

 In the hilly districts of J\lillburn, where there are a great many 

 large woodland pools or "kettle-holes" most all of which form ideal 

 breeding situations for this species, only a conlparati^'(dy f(>w 

 larvse occurred, and the resulting adults from this broo'd (piickly 

 disappeared. Each year that w^e study this form p'roduces addi- 

 tional evidence which points more and more to the- fact that this 

 species cannot be counted among the truly pestiferous ones. It 

 seems to^ disapipear entirely a few weeks after emerging from the 

 pu]>a, and this, coupled with the fact that it is rarely if evt'r found 

 out of the iunuediate woodland where it breeds, renders it one 

 wdiioh needs but little consideration from an economic standpoint. 

 In the pools where they occur, howeveir, certain other toi'ms occa- 

 sionally develop which are a menace to close-by dwellings, and ]!0(ds 

 treated for these will incidentally be freed from such ca.nadcii.sis as 

 may be piresent. 



Culex triseriatus, which normally 1>reeds in the Avater in tree- 

 holes and has on only Iwcv occasions beeai rcjMirtcd as occurring else- 

 where, once in an iron kettle and once in a few jxiols formed by a 

 drying brook, was found breeding contiiuiously in ])ails in uiy back 

 yard from mid-July until the end of August. Tlie larva' develojied 

 quickly, three distinct broods coming toi maturity in that s]Kice ol 

 time'. Most of the lar\a' were taken from the \n\'\\> a^ they neared 

 maturity, but a few develoiied to adults outdoors, and one of these 

 at one time was caught in the house toward evening. Two large 

 larval exam]>les wei'c taken with a full brood of (Uifcx siqiiifcr at 

 Chester on Jiovember 1 Ttli. 



Cidex serratiu'< was taken but once during the season, and then 

 only half a dozen larva' occurred among a lot of C. si/l resins 

 secured by Mr. Brehme, August (ith. on the Oi'aiige mountain-, a 

 new locality for its occurrence. 



Culex punctor. taken in New Jersey iu I'.M):. inv the tiist time, 

 and then only as an adult, was found in l'.M)(; as a larva on the 

 Oranffo mountains ami in the Livimistou Park woodland area near
