"The checkered white is not one of the more common butterflies in Houston. Despite its wide distribution, it is absent from much of Louisiana and eastern Texas, ranging into our area occasionally from the west ... Females are heavily checkered above with black or charcoal-brown, the underside of the hindwings lightly shaded with yellow-green or tan along the veins. Males are less profusely marked, with lightly checkered forewings and plain white hindwings."

This is the dorsal side.

This is one of BugGuide's Checkered Whites.
