from Kaslo, British Columbia, taken by Dr. Dyar ; Victoria, Van- 

 couver, September 9th, and Miniota, Manitoba, September 1st. 

 There are only single examples from each locality, indicating that 

 it is not exactly common ; but they are all very much alike, indica- 

 ting that there is no very great range in variation. There are 

 several examples from Kaslo in the collection of tl)e United States 

 National Museum. 



So far as examination has been made, the sexual tuftiugs of the 

 male correspond closely with those described for bicolorago ; but 

 material for destructive study has not been available.

In this species I have under examination a very interesting serie 

 of considerably over 200 examples. Besides my own collection, 

 there are more than 70 examples from the U. S. National Museum, 

 which are particularly useful because of the range of localities and 

 because there is a series of seven bred specimens; there is also a 

 series of about a dozen examples from the Museum of the Brooklyn 

 Institute, showing extremes of variation ; Mr. 0. Buchholz has sent 

 me a large number of examples, spread and unspread from Mani-
