On June 1st, 1901, while on a mosquito hunt with Mr. J. Turner Brakeley, at Lahaway, we investigated the little pools around the head of a swamp spring. The water was very cold, and our object was, mainly, to ascertain wheter Aedes larvæ occured in such localities, where pitcher plants were in the vicinity.In the course of our dipping I found a very odd little wriggler, altogether different from anything I had ever seen befor, and soon Mr. Brakeley found the same thing. We took only a few of them at that time, and from their minute size I assumed they must be very yound. I afterward sent a specimen to Dr. Howard, and he appeared as much at sea concerning its location as I was. It seemed to be a Culicid larva, without much doubt; but that was as far as we could get. The specimens were about an eight of an inch in length, light reddish in colour, and very hairy in appearance. The head was very broad, and from it the body taped gradually to the short obtuse anal siphon.
