cence gives a distinctly lunular appearance to the apical markings. Outer field 

 Ulteriorly fuscous divided by the yellow fuscous color of the veins— fading into the 

 ground color posteriorly. Hind wings fuscous, smooth, dark at margin. Beneath 

 fuscous on fore wings with a costal band lighter, the whole with a reddish tinge quite

 ( Ym/ia, a tribe of Indians of S. California). 

 Less roljust than the other genera. Head comparatively small. Palpi long, 

 curved back over head, heavily ridge scaled in front, thus becoming flattened, second 

 member long, third short. INIaxillary palpi long, pencil tufted in (^, the lobes slend- 

 erer than usual, the antepenultimate member long filiform. Antenm^ strongly bi- 

 tufted pubescent, tlie tuftings on the basal and middle segments raised on slight pro- 

 tuberances •/, the diameter of the segment, showing a beginning of pectination : 

 process short, slender, long scaled, without hairs. Wings without costal fold or vitri- 

 laction. Abdomen slender, tufted laterally on anti- and penultimate segments. 

 Genitalia normal, except that there are strong short lateral spines. Legs long, slender, 

 hind tarsi only slightly spined at tips. Fore tibice with epiphysis rather heavy, first 

 tarsus longer than tibia. Middle tibise not so long as femora, spurs long, the outer 

 very long, equalling "-/^ tibia. Hind tibite with end pair only of spurs, the tibiie being 

 twice the length of femora. Venation — Fore wings 12 veuis ; i not bent nor furcate, 

 3, 4 and 5 separate, 6 and 7 from a point, 9 and 10 stemmed with 8, 10 and II 

 separate. Hind wings 8 veins ; 3 separate, 4 and 5 joined at base, 6 separate, 7 and 

 8 :temmed beyond cell. Cell long, •/„ length of wing.

E.Npands, 20 to 26 mm. Head black with light gray scales intermingled. Tongue 

 light gray. Palpi black and gray intermixed, both washed with reddish. Process 

 whitish at base, becoming blackish at end, long scaled. Ocelli very distinct. Thorax 

 r-^.ddish brown in front, gray behind. Abdomen gray, blackish at base, with lateral 

 scJe tufts on the 2 segments preceding anal segment. Wings on the basal field dark 

 brown mixed with gray scales with a longitudinal light gray dash in center, running 

 two-thirds the length of the field and ending in a black point of raised scales preceded 

 by another. The field is limited quite distantly from base by a light gray strongly 

 thrice waved line which has beyond it a shadow line of dark brown. Beyond this the 

 middle field is gray, very light costally and centrally, darker posteriorly. Anteriorly 

 slightly washed, and shaded with a black discal point of raised scales, posteriorly 

 strongly shaded with brown which at the outer edge of the field is shghtly reddish. 

 The light gray centrally extends to the outer margin of the wing. Outer line clear 

 at costa, shaded inwardly and outwardly with black, the outward shading making a 

 large apical blotch. The line ends at the extension of the gray central field '/^ from 

 costa in a black longitudinal dash. It shows somewhat indistinctly on the posterior 

 '/j in the continuation of the reddish brown of the middle field, and is there waved 

 inwardly, dentate outwardly, and shaded on both sides with blackish. Outer field 

 narrow, gray, except towards posteiior angle where it is brown, slightly reddish. 

 A black marginal line cut by the veins. Fringes interlined. Hind wings yellowish- 

 white, somewhat fuscous, subpellucid. An outer line dentate outwardly on veins. 

 A black marginal line cut at veins. Fringes interlined. Beneath dark fuscous washed 

 over dirty white, an outer indistinct dentate white line on fore wings. Hind wings 

 nearly as above but duller.
