Adult Markings: In this species the head and thorax are brown with white speckling. The forewing has complex patterning that mostly consists of a brown ground color that is intermixed with whitish lines and patches and dark brown marks. The wing base has a distinctive white line that starts on the inner margin and extends obliquely to the base, then angles sharply apically to run parallel to the costa. At about one-fourth the wing length it typically connects to a group of diffuse and often fused whitish patches that extend from the inner margin to the line. The line then continues forward, narrows, and angles back to connect to the costa at about one-third the wing length where it fuses with a narrow, white costal streak. The costal streak extends apically and arcs inward before terminating below a white, trapezoidal patch at about three-fourth the wing length. The patch is just proximal to a white subterminal line that is margined narrowly with black inwardly. The line slants from the costal towards the outer margin then sharply angles basally and curved to meet the inner margin perpendicular at around four-fifths. Three other conspicuous white marks are present on the forewing that include an elongated streak just below the boldly, double-lined apex, a squarish patch in the middle of the subterminal region that adjoins the subterminal line and is often intersected by a dark brown line, and a dagger-shaped mark in the middle of the wing at around one-half the wing length. The white postmedial line is highly jagged and extends from the inner margin just beyond the middle of the wing before terminating near the center of the wing. The hindwing is uniformly brown with a pale fringe that has a narrow, dark basal line.
