Psyche 
[June-September 
However Buckell (1924) states that both species have been seen at 
Nicola, B.C. “in large numbers during late May feeding together 
upon flowers of Amelanchier . . .”. 
We have examined about 300 specimens of monstrosa and 200 of 
buckelli. In addition to the type, allotype and paratypes of strepi- 
tans, we have seen 20 or so alcoholic specimens supplied by Dr. R. 
Willey of the Univ. of Chicago. Dr. Willey’s material is from Los 
Pinos Pass, Col., a locality which he discovered in 1962 (Willey & 
Willey, 1963). 
All plotted localities are based upon actual examination of 
specimens excepting Wind River, Wyo. This record is taken from 
Thomas (1876) on the strength of his illustration of an adult male. 
Though the drawing is small the shape of the sternal process is 
apparent and marks the specimen as strepitans. A listing of localities 
is given below for each species.
