Explanation of Names
BRUMOSA: from the Latin "bruma" (winter)
"brume" [n.] - fog or mist; "brumous" [a.] - characterized by fog or mist
perhaps a reference to the patchy and indistinct markings on the forewing, reminiscent of fog or mist
Wingspan about 38 mm.
Adult: forewing a patchy mixture of black, gray, and white, with no sharply-defined markings; basal, anal, orbicular-reniform, and subterminal dashes present but diffuse and indistinct, showing little contrast against dark ground color of wing; postmedial line double, whitish, faint; orbicular spot oval, whitish, with dark dot in center; overall appearance seems mottled and diffuse, as though obscured by patches of fog. Thorax mottled dark gray; basal segments of abdomen brownish-orange.
