The genus Neotibicen comprises large-bodied Cicadidae appearing in late summer or autumn in North America. Many colloquial names exist for Neotibicen, including locust, and dog-day cicada. Until recently, these species were all in the genus Tibicen, which was redefined so as to include only a few European species, while species from the Western US and Mexico are now placed in a separate genus, Hadoa.
