among the bushes, while females were taken readily in flight. 

 They were not especially blood-thirsty, and while they would 

 bite if left undisturbed, they were easily scared off. Among 

 those that were taken in flight was one example filled with 

 blood, which had not been obtained from any of our party. 

 It was taken deep in the woods near an old spring, and it is 

 doubtful whether any human being had been in that immedi- 

 ate vicinity for a month. There was no house within half a 

 mile, and no traveled road anywhere near ; yet from some 

 source this specimen had obtained a meal of blood. Larvae 

 and pupae were found everywhere in the road and other wood- 

 land pools, and in all the springs that we examined. All the 

 adults bred proved to be ca?iadensis. Followed out the cour.se 

 of a small stream through a marshy meadow and examined 

 numerous pools, finding wrigglers wherever there was no sedi- 

 ment of iron ru.st. There is much bog iron here and most of 

 the pools are " rusty "; where this was the case, there was no 

 mosquito life. I verified the fact that none of these mosqui- 

 toes came to the house only a few rods off, and noted that 

 where the abdomen was distended in those I caught, the crop 

 contents consisted of a clear, ahnost colorless liquid. At this 

 time very minute larvae were found in the pools with those 

 that were full grown — exactly the condition noted by Mr. 

 Brakeley on the i6th. Assuming that the brood maturing- 

 June I St was that started May i6th, it would give a 15-day 

 period for the full development. As adults recently hatched 

 were seen in numbers. May i ith, it would mean that the larvae 

 from which they came were in the pools during the latter part 

 of April. Many of these pools came into existence during the 

 winter — how did the larvae get into them in spring? Many 

 places containing larvae June ist were fast drying up into mere 

 mud holes and would hardly be anything else until the follow- 

 ing winter. 



Nothing more was done with this species during the sum- 

 mer of 1901 ; but in October, Mr. Brakeley took the matter up 

 again and reported larvae in one of the springs on the i6th, 

 after there had been frost and ice. On the 27 th. of the same 

 month, larvae and pupae were obtained from the springs, and
