754 MOSQUITOES OF NORTH AMERICA 



two filaments before tip ; an outer row of cilia from a collar; eleven filaments on 

 outer edge ; dentition of four teeth on a process, the first longest; a filament and 

 two unequal teeth before ; a broad filament and six feathered ones within, unusu- 

 ally large; process below furcate, with patches of hair; a pointed basal angle, 

 with four long hairs within; a long row of hairs at base. Maxilla elongate 

 hemispherical, divided by an oblique suture; inner half with rows of hairs, a 

 large tuft at vertex; outer half with a band of hair, two filaments next ttie 

 suture toward apex and a spine on the other side ; palpus short, with four small 

 digits and a central elevation. Thorax wider than long; hairs moderate. 

 Abdomen rather stout, the anterior segments shorter; lateral hairs single on 

 segments 3 to 6; tracheal tubes broad, band-shaped. Air-tube stout, about 

 three times as long as wide; pecten usually evenly spaced, occasionally with 

 some of the terminal teeth somewhat detached, reaching less than half the 

 length of tube, followed by a single tuft of two or three hairs ; single spine long, 

 slightly widened at base, with two small branches rather far out. Lateral comb 

 of eighth segment of a very few scales in a line ; single scale elliptical, fringed 

 with short spinules and with one very long stout terminal spinule. Anal seg- 

 ment longer than wide, ringed by the plate ; dorsal tuft a pair of long hairs on 

 each side ; ventral brush well developed, confined by the plate ; anal gUls moder- 

 ate, tapered. 



The larvae appear in the early spring, hatching from the overwintering 

 eggs. There is but a single annual generation. The larvae occur mixed with the 

 other early spring species in woodland pools and marshes, often when ice is still 

 present. Mr. Knab and Dr. Dyar collected nearly fully-grown larvae from a 

 marsh by standing upon ice at its edges and dipping under the ice, where the 

 larvae had taken refuge. The females live for two or three months in the woods, 

 and soon become much worn, being then indistinguishable from other species of 

 Aedes with similar habits. 



Northeastern United States, probably also in Canada. 



Plattsburg, New York, larvae April 24, 1905 (H. G. Dyar) ; Dublin, New 

 Hampshire, May, June, 1909 (A. Busck) ; Springfield, Massachusetts, April 28, 

 1903 (F. Knab) ; Wilbraham, Massachusetts, June 4, 1903 (F. Knab) ; Mount 

 Tom, Massachusetts, May 6, 1903 (F. Knab). Reported also from Orange 

 Mountains and New Brunswick, New Jersey (Morse). 



It seems probable that Aedes abserratus has a wider range than indicated by 

 our localities. Its distribution seems northern, and it is probably due to chance 

 only that no specimens have appeared in our collections from Canada. This 

 species has been referred to by several American authors under the name 

 punctor.
