empty pupa-skins were found in a rather large road puddle 

 near a cranberry-bog. This place is always moist, and was 

 probably filled with water all winter ; but it does lose all water 

 during the summer except after a heavy rain. In the shallow 

 edges of a reservoir close by, no larvae were found and none 

 were found in road-puddles out of the woods. Adults emerged 

 later in the day from some pupae, and many larvae pupated ; 

 the usual period of the pupal stage being 3 to 4 days. All the 

 adults were sent to me and all were canadensis, the determina- 

 tion being made by Mr. Coquillett. 



May 13th, another tour of investigation turned out a lot of 

 very small blackish wrigglers as well as others that were 

 almost or quite full grown, and the indications were that a 

 second brood was already developing. In a spring, filled with 

 leaves so that not a drop of water was visible, the leaves were 

 .shoved aside and in the water beneath, some half -grown wrig- 

 glers were found. Mr. Brakeley noted that these larvae were 

 much more active and " scary " than tho.se found in the pitcher 

 plants, and he suggests as a reason that they have more natural 

 enemies to fear, and are hence more easily startled. 



May 14th, quite a number of adults were noted in the woods, 

 and again it was noted that they manifested no inclination to 

 bite. Nor did any of them come to the house which was very 

 close by — certainly not over 500 feet from the edge of the 

 woods ! They seemed to be, strictly speaking, woodland mos- 

 quitoes. 



May 1 6th, the number of mosquitoes was much reduced ; 

 but very small larvae were now found along the edge of the 

 reservoir where it was more or less gra.s.sy, and many empty 

 pupa shells were seen. 



May 17th, adults began to i.ssue from pupae that had formed 

 subsequent to May 12th, and an average period of 3!^ days 

 was e.stal>li.shed for this stage. A lot of the young larva- was 

 secured, but they did not do well in confinement and soon 

 diefl. On the 19th, the full grown larva- and pupic had dis- 

 appeared, and only small si)ecimens were .seen. 



June ist, I was at Lahaway and found this .species common 

 in the woods. Males were obtained by sweeping with tlu- net
