This form inhabits the eastern forested region, extending to 

 the Canadian plains, where it seems to merge into the next sub- 

 species. The larvae are found in the early spring pools of a 

 marshy or semipermanent character, the adults flying until late 

 in the summer.

In the last quoted reference I discuss the differences shown 

 by the western race of fitchii in the larvae, but state that there 

 is no name applicable to the form. Pending further research, 

 I propose to apply the name mimesis in this sense. The type 

 locality is Montana, the larvae undescribed. I take the general 

 habitat to include the Rocky Mountain region from Montana 

 to the Yukon Valley.
