Botys generosa Grote & Robinson, 1867
Expanse (♂): 20 mm.
Length of body: 8-9 mm.
Head, palpi and thorax, above, dull obscure blackish; abdomen, blackish, the segments narrowly edged posteriorly with yellowish. Beneath, the palpi, legs and corporal parts are whitish testaceous, silky.
Anterior wings, dull obscure blackish, shaded obscurely and largely with dull brownish over the middle; two transverse dull black lines; the sub-basal acutely dentate, the last outward inflection the most prominent; the sub-terminal, oblique, finely dentate, inwardly inflected below the middle of the wing. A squarish, yellow, discal spot. At the costa, the sub-terminal transverse line is broadly bordered outwardly by a yellow band which, below the first median nervule is obsoletely and quite narrowly continued to internal margin. Terminally, the wing is dark colored, and there is a faint series of black nervular marks before the external margin, on which latter rest a terminal series of interspaceal dark dashes obsoletely separated; fringes, dark, paler at their outer extremities. Posterior wings, black or blackish; a yellowish discal spot, and the base shows a few scattered yellowish hairs; a very broad and evident median yellow band, widest superiorly where it does not attain the costal margin, tapering to anal angle which ,it hardly reaches; fringes, whitish, as is the costal margin. Under surface of wings, pale yellow; a black discal dot, sub-terminal band (this on the primaries is very broad, oblique, and discontinued at about the center of the wing, when, below it, the sub-terminal line of the upper surface is apparent), and a broad, terminal, black shade on both pair of wings.

Pyrausta subgenerosa is very similar. However, it is found west of the Rocky Mountains and is smaller; forewing uniformly dark brown, without yellowish variegation; yellow spot between orbicular and reniform minute, but distinct; yellow subapical costal bar almost linear and narrower, about four times as long as wide (this subapical bar in generosa is more oblong and about twice as long as wide); hindwing as in generosa.
