Résumé
<i>Sympistis chons</i> Troubridge sp. n. (Figs. D-18, D-19, D-20, M-7, R-4) <b>Diagnosis.</b> <i>Sympistis chons</i> can be distinguished from <i>S. amun</i> by the characters given above, except in the Peace River Valley, British Columbia and Alberta, where <i>S. chons</i> is very dark and looks much like <i>S. amun</i>. DNA analysis puts these northern specimens with <i>S. chons</i>. This species becomes paler towards the south, where the forewing is light gray and the hindwing marginal band almost absent in some Arizona specimens. On the Great Plains, <i>S. chons</i> occurs in badlands and dry river valleys and <i>S. riparia</i> occurs on dunes. The subterminal line of <i>S. riparia</i> is present as an undulating pale line or series of pale dots (Figs. E-2, E-3); that of <i>S. chons</i> is more deeply jagged, particularly in the anal angle. In the south, <i>S. chons</i> could be confused with <i>S. deserticola</i> or <i>S. major</i>. The orbicular and particularly the claviform spots of <i>S. deserticola</i> (Fig. D-12) and <i>S. major</i> (Figs. D-13, D-14) are highlighted with white scales; these spots are less contrasting and light gray rather than white in <i>S. chons</i>. <b>Description</b>. Antennae filiform, prothoracic collar hoary charcoal gray with wide, light gray median band diffuse charcoal median line within the median band; head and thorax a mix of black and light gray scales gives a hoary dark gray appearance; abdomen light grayish brown. Coremata with brushes, levers, and pockets present on base of male abdomen. Forewing length 15-17 mm. <b>Dorsal forewing</b> light gray and black scales give forewing powdery gray appearance; antemedial and postmedial lines usually obscure, absent, or present as black dots on veins; orbicular spot ellipsoidal; orbicular, reniform, and claviform spots dark gray, bordered with light gray or scattered white scales on the inner row and thin black outer row of scales; thin black basal dash extends into claviform spot; black lines extent through each cell in subterminal portion of wing, meeting black terminal line which is present as a series of small chevrons between veins; slightly obscure, white subterminal line deeply denticulate; fringe dark gray, lightly checkered with light gray at tips of veins. <b>Dorsal hindwing</b> very light grayish basal area blends to dark grayish brown terminal shade in male, slightly darker in female; veins and discal lunule highlighted with scattered grayish brown scales; fringe white with narrow gray median line. <b>Male genitalia</b>. (Fig. M-7) Valve shaped like the prow of a canoe with distinct corona; ampulla of clasper squat, bends posteriorly with terminal spine arcing upward from posterior margin. Vesica with two small basal diverticulae, bends slightly downward about ½ of the way from base; a ribbon of sparse cornuti extends dorsally from base of vesica to apex; a second ribbon of longer, stouter cornuti extends dorsolaterally on right of apical ½ of vesica; a single spine and a tuft of longer cornuti extend from apex. <b>Female genitalia</b>. (Fig. R-4) Ovipositor lobes rounded, apex with ring of long setae, corona of short setae mid way down -these setae produced at 90° to the abdomen; a ruff of longer, finer setae encircles ovipositor lobes at base; a small sclerite occurs on ventral surface of ductus bursae at ostium bursae, ductus bursae elongate, widening slightly in middle ½ and then narrowing at appendix bursae; appendix bursae elongate gradually narrows toward ductus bursae, rounded at anterior end with ductus seminalis arising from ventral side of anterior end; corpus bursae about ½ as large as appendix bursae arises from left side of appendix bursae near ductus bursae, elongate signae on dorsal and ventral sides. <b>Type material</b>. <b>Holotype</b> male: Canada, British Columbia, Kirby Flats Rd., 50° 32' N, 121° 43' W, 7 vii 2000, J.
