XYLOMIGES Gn. 1852, Gn., Sp. Gen., Noct., i, 147. Byes hairy, round, moderate. Head small, retracted, with even, short, still', scaly vestiture, forming superposed flattened frontal tufts. Palpi short, reaching to, but scarcely exceeding, the front. Tongue loug and strong. Antenna? in the male pectinated, serrate and bristled, or ciliate merely. In the female they are simple, only sparsely ciliated. Thorax robust, quadrate, convex, with a variably distinct anterior and posterior tuft. Abdomen dorsally tufted. Legs unarmed, save for the ordinary spurs of middle arid hind tibia?. Primaries narrow, trigouate, elongate, with marked apices and obliquely rounded outer margin, or short, narrow, and stumpy. From Mamestra this genus differs by the shorter palpi, the more retracted head, the superposed frontal tufts, the wing form, and in some instances by the pectinated antennae. From Morrkonia it differs in not having the divided thoracic crest, the thorax itself stouter, the abdomen not so loug proportionately, and the primaries not retracted at anal angle nor strigate in type of maculation. From Stretchia (Perigrapha) the species differ in the thoracic tuftings and somewhat also in wing form. Strictly, only two of our species--curialis and dolosa--are congeneric with the European conspicillaris; but there is no safe line for the separation of any of the species, save possibly patalis, which differs by the habitus, the short stumpy wing, somewhat depressed body, and simple male antenme. Autennal characters are weak in the hairy eyed genera, and so indeed are most others. It is difficult to limit the genera in this s...
