NOTES ON SOME MOSQUITOES NEW TO CANADA. 



BY ERIC HEARLE, 

 Guelph, Ont. 



Psorophora sayi Dyar and Knab. 



This beautiful insect has not previously been recorded from Canada, 

 although it is reported from the Atlantic and Gulf states, the Mississippi Valley, 

 Cuba and the Bahamas. 



The single specimen obtained by the writer was taken near Jordan, On- 

 tario, on August 3rd, 1916. It was in woods, attempting to bite at 8.30 in the 

 morning. With it were a number of Aedes canadensis. 



This is a very distinctive mosquito; in the sunlight most of the scales give 

 off vivid purple reflections. The hind tibia and some of the hind tarsal segments 

 have many erect, dark purple scales which give a brush-like appearance to 

 these parts. The apices of the hind legs are white: the two distal tarsal seg- 

 ments and part of the preceding one being entirely white-scaled. The abdomen 

 is dark-scaled, the scales having violet reflections. At the apex of each seg- 

 ment, on each side, there is a lateral yellow triangular patch. The venter is 

 yellow-scaled. 



Aedes triseriatus Say. 



There is no previous Canadian record of this very interesting little mos- 

 quito. Howard, Dyar and Knab give its distribution as the United States 

 east of the Rocky Mountains. 



The writer found the species to be a fairly common one in woods in Southern 

 Ontario. Females only were taken and these were found to bite fiercely during 

 the day, but collections made after nightfall gave no specimens. Quickness of 

 movement and a highly-strung sense of danger characterizes the species which 

 is a very illusive one.
