(Figs. B-23, L-3, P-13)  
 Diagnosis. Sympistis osiris most closely resembles S. isis sp. n. in that the forewing is a rusty brown color; however, the basal hindwing is cream colored in S. isis and off-white in S. osiris. In S. osiris, the entire length of vein 1A+2A and veins CuA2, CuA1, and M3 beyond the postmedian line are widely bordered with gray scales, rusty brown in S. isis. Internally, the ampulla of the clasper of S. isis is situated closer to the apex of the valve than in S. osiris, also, in S. osiris, the ampulla is bent ½ of the way from base to apex but in S. isis, the ampulla arcs evenly without a noticeable bend in the middle.   
 Description. Antennae filiform. Prothoracic collar light brown then a thin black line, light brown, black, brown and white lines. Head brown with scattered black scales; vertex with a row of dark brown below a row of white scales; thorax a mix of brown, black and white scales. Coremata with brushes, levers, and pockets absent from base of male abdomen. Forewing length 14-16 mm. Dorsal forewing ground color rusty brown; ordinary lines not sharply defined; white scales located basally on the radial veins; obscure black antemedial line bordered basally with light rust scales; obscure, black postmedial line edged distally with light rust scales; obscure median line dark brown; basal line black; veins from base through postmedial line edged with white and gray scales, black on veins and widely bordered with gray scales between postmedial line and subterminal line; black dashes extend between veins through postmedial area almost to terminal line; subterminal line occurs as a series of light rust dots within these black dashes; black terminal line edged basally with light rust chevrons; orbicular, reniform, and claviform spots well demarcated with thin black outer and light rust inner lines with an inner ring of darker rust scales; fringe a series of light rust, dark rust, dark grayish brown and finally dark grayish brown mixed with white lines. Dorsal hindwing basal area off-white; submarginal band dark grayish brown; discal lunule and veins CuA and CuA2 lightly highlighted with darker scales; fringe white. Male genitalia. (Fig. L-3) Valve with rounded, upturned apex; ampulla of clasper tapers evenly to apex with distinct bend about ½ way from base to apex. Vesica with basal diverticulum on right arcs to the left beyond diverticulum; a ribbon of fine, sparse cornuti extends from dorsal base of vesica across diverticulum, tapering off on dorsal surface; a second ribbon of cornuti extends along dorsal surface of apical ½ of vesica; a third ribbon of longer, coarser, ventral cornuti on apical ½ of vesica; a single, coarse apical cornutus and small bundle of cornuti projected from apex. Female genitalia. (Fig. P-13) Ovipositor lobes rounded with scattered setae; a corona of short setae surrounds ovipositor lobes near tip, these setae produced at 90° to the abdomen; a ruff of longer, finer setae encircles ovipositor lobes at base; a sclerite occurs on ventral surface of ductus bursae at ostium bursae; appendix bursae bulges ventrally near ductus bursae then bends to left as it widens and twists dorsally, rounded at anterior end where ductus seminalis arises on dorsal side; corpus bursae absent.   
 Type material. Holotype male: USA: New Mexico, Sierra Co., Hwy. 51 SE of Elephant Butte, 17 x 2001, George J. Balogh, in the CNC. Paratypes: 6♂ 5♀: New Mexico: same data as holotype, 2♂ 2♀. Texas: El Paso Co., East Montana Hwy., 7-9 x 1993, E. Knudson, 2♂ 3♀; El Paso Co., Hueco Tanks SP, 7 x 1993, E. Knudson, 1♂; El Paso Co., East Montana Hwy., 7-9 x 1993, E. Knudson, 1♂.   
 Etymology. Sympistis osiris is named for Osiris, Egyptian god of the underworld. He was married to Isis and father to Horus. Like the mythology, S. osiris, S. isis and S. horus form a closely related group. It is a noun in apposition.   
 Distribution. This species is known from southwestern New Mexico and extreme western Texas.
