Their apices are acute to acuminate while the surfaces are glabrous, puberulent, or hirsute-ciliate, meaning with longer, shaggier hairs.
The proboscises often have sharp apices as well as a host of barbs and spurs on the stem.
The hindwings are white, shading to grey at the apices.
Antennae longer than body, extending beyond apices by 3-4 antennomeres.
The forewings are shining ochreouswhite, but more whitish near the wing base and more ochreous near the apices.
Their alternate leaves are ovate-elliptic, with margins entire or occasionally repand, with acute apices and broadly cuneate to subrounded bases.
The 23 mm long calyx teeth are ovate-triangular in shape and are subequal or the posterior teeth larger, with rigid apices.
The apexes are often 1 cm or more from the tumor, so clear margins at the apices can be ignored.
