The scattering records of rustica indicate that it is an inhabitant 
of the Boreal, Transition and Austral life zones. The larger part of 
the records are confined to the humid divisions of the Transition and 
Upper Austral life zones. Future records will doubtless extend the 
range of this race, which is now known from the Canadian, Upper 
Mississippian and Rio Grandian regions. Its range is probably co- 
extensive with that of Galba humilis modicella.
