noying species. Not only during the latter part of the sum- 

 mer does it become troublesome around the houses and the 

 parks, but even as early as the month of June (1908), it has 

 been found in the city in large numbers. 



So frequently have the larvae been collected in roadside 

 ditches, in marsh pools, and in other situations within the 

 limits of the city, and so commonly have the adults been ob- 

 served in this region, that a page of local records could be 

 given, were it necessary. As the habits of this mosquito are 

 well known, it will suffice to say that the earliest record for 

 the adults is May 16; the latest, October 6. 



Aedes gylvicola Gross. 



One male was bred from some larvae which were collected 

 in a ditch in a semi-woodland tract near Seventy-ninth Street 

 and East Avenue, on April 28, 1907. This specimen and an- 

 other taken at Palos Park, on May 30, 1907, are the only rep- 

 resentatives of this species that can be recorded. 



Aedes taeniorhynchus Wied. 



One specimen, a female, was collected May 18, 1906, on the 

 south side of the city, by Mr. Charles A. Hill. This is the 

 only mosquito with a white-banded beak that was taken in this 

 region. 



Aedes triseriatus Say. 



Specimens of this aggressive but rather rare woodland mos- 

 quito were collected at Beverly Hills (August 18 and 25, Sep- 

 tember i, 1907), and near Bowmanville, a suburb in the north- 

 ern part of Chicago (October 6, 1907). 



Aedes trivittatus Coq. 



Not observed within the limits of the city, but in the tracts 

 of woodland near the following places the adults were some- 

 times rather common and always ready to bite, occasionally 

 being quite persistent in their attacks: Beverly Hills (August 

 18 and 25, 1907; July 13, 1908); Willow Springs (July 14. 

 1908); Palos Park (July 15, 1908; at light, September 4, 

 1909) ; Glen Ellyn (August 2, 1908), and Hessville, Ind. 

 (July 12, 1908; August 29, 1909).
