Remarks: Morris (1870: 227) validated the name serricornella . However, he followed Doubleday (1859: 34) in regards to the identity of the species. Doubleday, in turn, concluded that serricornis was a ‘synonym’ for serricornella . E. serricornis Stainton, 1854: 260 is the oldest name available, and E. serricornella is thus an unjustified emendation.
