Adult Markings: A moderately small deltoid with a blue-gray ground color, particularly in the basal area and along the costa; the area beyond the reniform may be shaded with yellow or with darker fuscous in some individuals. The lines are dark black and strongly waved or dentate and expanded towards the costa. The orbicular is yellowish and reniform consists of a yellow crescent followed by a reddish-orange patch (Forbes, 1954). A continuous black terminal line exists, followed by a checkered fringe.
