Overview of Species
The diagnosis of species depends on the presence of absence of an anterior Banksian line in the hind wing. This is a line of venation at the wingtip that runs a ways down the length of the wing due to bending of the RS branches (see figure below).


V. americana: anterior Banksian line present and distinct in the hind wing; forewing 52-60 mm; eastern(4)
V. eggerti: Banksian line absent in the hind wing; forewing 50-70 mm; eastern: FL Keys only(5)
V. fallax texana: anterior Banksian line absent in the hind wing; forewing ~48-55 mm; western(4)
Range
2 spp. in e. US + 1 sp. in w. US(2)
