Arizona, June to September inclusive. This species is smaller 

 and darker than cellus, lacks the terminal pale area on the under 

 surface of the secondaries and has a pale ring at the base of the 

 antennal club. I have examined a long series in the Barnes 

 collection without finding any specimen in which the pale ring 

 could not be seen.
