Polynomial functors and representations of wreath products

Any reflection group has a graded representation on the cohomology
of the corresponding hyperplane complement  the character of this
representation has been calculated in most cases by Gus Lehrer.
I will discuss an alternative approach in the case where the group
is the wreath product of a symmetric group and a cyclic group.
This uses a generalization of the classical link between composition
of polynomial functors and plethysm.
