Megathymus yuccae yuccae ♀ original illustration of SYNTYPE, USA: (likely) GEORGIA
This appears to be a composite illustration of two species.
While the wing shape fits M. y. yuccae rather well, the pattern is clearly that of M. cofaqui.
A comprehensive discussion of possible origins for such a discrepancy can be found here.
Since the Neotype has been designated, there are no taxonomic implications for this discrepancy.
