33 INSECUTOR INSCITI^ MENSTRUUS 



This widespread species was found in the timbered country 

 in the lake region. Eighty-five examples are at hand, as fol- 

 lows : Dryden, Ontario, June 30-July 2, 1918; Kenora, On- 

 tario, July 2, 1918. 



Swarming was observed at both Dryden and Kenora. The 

 males appeared after sunset, swarming in a similar manner to 

 Aedes punctor and lasarensis and in company with these spe- 

 cies, although the swarms did not become mixed together.

 tends outside of it, reaching the Pacific coast and the moun- 

 tains of California. Only five specimens were found : White 

 River, Ontario, June 12-22, 1918 ; Red Deer, Alberta, August 

 1, 1918. At Red Deer a single male flew out of a cold well, 

 but it was not possible to ascertain whether there were any 

 larvae in the water.
