though only in small numbers. It does not appear to be a par- 

 ticularly troublesome form locally. 



Swamp mosquito (Aedes sylvestris Theo.). This m.edium or 

 small mosquito has the tarsi narrowly white-banded basally. It was 

 taken the latter part of June, during July and also in August, mostly 

 in and about swamps, especially at First and Second creeks and 

 Wintergreen point. Larvae were extremely abundant on Sand point 

 August 14th following heavy rains, and were also found at this time 

 in the large swamp area near the village. Under certain conditions 

 this species is probably very abundant and annoying. 



Golden-scaled mosquito (Aedes aurifer Coq.). This medium- 

 sized, black mosquito with its conspicuous golden yellow scales on 

 the sides of the thorax, is preeminently a woodland swamp form and 

 was found abundantly under such conditions from June 7 th to July 

 2 2d, it being particularly numerous in and about Lake BluflE swamp, 

 though it was also found in a large swamp near Sodus Point village 

 and in the vicinity of Second and Third creeks. This mosquito is 

 one of the most bloodthirsty, attacking quickly and in numbers 

 whenever there is an opportunity, though on account of its being 

 limited so closely to sylvan conditions it is not troublesome to any 

 extent in and about human dwellings. 



Aedes impiger Walk. Larvae of this com.mon native species were 

 taken in temporary pools in early July near Sodus Point, though in 

 no case were they very abundant. This species appears to breed 

 largely in small, temporary, woodland or swamp pools in associa- 

 tion with A. canadensis and the series of species usually 

 occurring under such conditions. It does not appear to be par- 

 ticularly important as an annoying form. 



Three-striped mosquito (Aedes trivittatus Coq.). Two 

 specimens of this mosquito were taken July 26th on Newark island. 

 The adidts have three black, longitudinal stripes with a yellow 

 background on ' the thorax, while the legs and beak are unhanded. 

 The wings are unspotted and the abdominal segm,ents have lateral, 

 basal white marks, which frequently unite to form transverse 

 bands. This woodland form is reported as a fierce biter. It 

 appears to fly low most of the time, since attacks are usually confined 

 to the lower extremities, it rarely biting above the knees. 



Tree Hole mosquito (Aedes triseriatus Say). This is 



another comparatively rare mosquito which breeds very largely in 



tree holes, hence its common nam_e. A few larvae were m.et with 



August 24th in a characteristic depression near Second creek,
