AMERICAN LEPIDOPTERA. 25 



S. colorartella, n. sp.— Head ochreous, brownish above the antenna! inser- 

 tion. Labial palpi rather slender, yellowish gray, pale fuscous externally, apex 

 of terminal joint pale; brush of second joint very short, compressed into a cut- 

 ting edge, the third joint nearly as long as the second and slender. Maxillary 

 palpi rather short, thickened with scales and more distinctly folded ; dusted with 

 fuscous. Antennae scarcely one-half, pale ochreous, joints not close set, each with 

 a whirl of dark brown scales, giving them a distinct annulate appearance, 

 strongly fasciculate-ciliate in the male, cilia fully 2. Thorax pale yellow. 

 patagia anteriorly and disk speckled anteriorly with dark brown. Forewings 

 deep purple-brown, markings yellowish white; a number of short transverse 

 strigse on the costa, of which two or three in the last third of the dark part are 

 more distinct than the rest. Apical part of wing and termen broadly pale yel- 

 low, this pale portion is widest on the costa and slightly sinuate into the dark 

 portion, irrorated with dark spots and two or three short, confluent spots on the 

 costa before the apex. The pale dorsal portion is widest at the base and projects 

 as a triangle into the dark portion about the middle and again at beginning of 

 the dorsal cilia, not obviously spotted with dark fuscous, except slightly beyond 

 dorsal cilia, ('ilia pale yellow, with dark line near the base. Underside of fore- 

 wing dark fuscous, tinged with purple and showing the pale markings of upper 

 side. Hindwings pale grayish fuscous, cilia pale, with indistinct dividing line, 

 underside grayish fuscous. Abdomen grayish fuscous, tinged with yellow, anal 

 tuft grayish ochreous. Legs yellowish, dusted with fuscous, anterior tibiaj and 

 tarsi dark brown, joints of the latter pale at apex. 



Exp. 28.0-30.0 mm. ; 0, 1.12-1.20 inch. 



Hub. — Colorado (Durango) ; Texas; New Mexico (Beulah).

Very closely resembles anatomella in size and coloration, but is 

 readily distinguished aside from differences in wing markings by 

 the more slender labial palpi, the long ciliation of £ antennae, and 

 the latter being distinctly annulate. 



S. fuscofasciella Chamb.— PI. II, fig. 1. — Dyar's List, p. 568, No. 6474. 



Doubtfully referred by its authors to Euplocamus. I here give 

 his description verbatim : 



"The palpi are brown on the upper and external surfaces, and on the basal 

 portion of the tuft beneath ; on the inner surface they are yellow. 



"Head sordid yellowish; antennae brown ; thorax and patagia brown at base, 

 but becoming yellowish towards the tip. To the naked eye the forewings appear 

 yellowish, mottled with brown, with some distinct brown spots and a rather wide 

 irregular brown fascia behind the middle, the anterior margin of which is straight 

 from the costa to the fold, but having the posterior margin angulated backward 

 about the middle of the wing, at the fold the fascia is narrowed suddenly be- 

 hind ; the basal portion of the wing is distinctly brown, and there are two dis- 

 tinct brown spots in the apical part of the wing. Under the lens the entire wing 

 appears to be traversed transversely by numerous, narrow, interrupted, confluent 

 and irregular brown lines on a yellow ground, the brown of the fascia and base
