We give a geometric construction of representations of parahoric subgroupsof a reductive groupover a local field which splits over an unramified extension. These representations correspond to charactersof unramified maximal tori and, when the torus is elliptic, are expected to give rise to supercuspidal representations of. We calculate the character of these-representations on a special class of regular semisimple elements of. Under a certain regularity condition on, we prove that the associated-representations are irreducible. This generalizes a construction of Lusztig from the hyperspecial case to the setting of an arbitrary parahoric. References
