Amclanchier canadensis. 
1. Nepiicula amelanchierella Clem. 
This is found in the leaves of the service-berry or June-berry, Amelan-

Early in August the larva may be found in the leaves of June-berry 
or service-berry making Lithocolletiform mines on the under surface. 
Towards the middle of the month, it abandons its mine and feeds under
