Subfamily: Pyrginae
Identification: Antennal clubs are blunt. Upperside brown; forewing with 2 wide gray bands and no transparent spots. Male has a costal fold containing yellow scent scales; female has a patch of scent scales on the 7th abdominal segment.

In the east from Manitoba south through southern Ontario and the eastern United States to central Florida, the Gulf Coast, and central Texas.
