AMERICAN LEPIIH3PTKRA. 53 



body at) d hind legs grayish oclireous ; anterior and middle legs fuscous, tarsal 

 joints pale at apex. 



Exp. 18.0-19.5 mm.; 0.72-0.78 inch. 



Hab. — California (Pasadena). 



A number of specimens in my collection. Erroneously referred 

 to Trichophaga in Dr. Dyar's List. 



T. I uscanella n. sp. — Palpi whitish, labials rather thick, dusted with fus- 

 cous, terminal joint rather short, obtuse. Head creamy-white, slightly yellowish 

 in front and a few tufts of brown upon the face. Antennae fuscous brown, paler 

 beneath, basal joint whitish. Thorax brown, enclosing a large oval patch of 

 white anteriorly. Wings a little narrower than in occidentella. Forewings whit- 

 ish, overlaid with brown scales; which are most dense in the dorsal and apical 

 portions of the wing, less along the margins and adjacent parts, the space snr- 

 rounding the second discal spot being the. most sparsely dusted portion of the 

 wing; plical spot distinct, about middle of wing length, first discal obsolete, sec- 

 ond distinct, rounded. Cilia whitish ochreous in basal half, outer half brownish, 

 separated by a dark dividing line, another less well-marked line in the outer 

 half; the whole sparsely speckled with brown scales; underside pale fuscous. 

 Hindwings as wide as forewings, rather pointed, pale silvery gray, margins fus- 

 cous and apical part rather densely dusted with darker scales ; cilia pale yellow- 

 ish ; underside deep ochreous towards the dorsal margin. Abdomen ochreous 

 fuscous, paler on the sides above. Legs pale ochreous, anterior two pairs tinged 

 with fuscous, tarsi annulate with dark. 



Exp. 17.0 mm. ; 0.68 inch. 



Hab. — Arizona (Tuscan). 



Very closely related to occidentella, from which it differs by its 

 narrower wings, the dusting rather brown than blackish, the plical 

 spot farther from the base and the cilia pale at base. 



Croceocapitella Group. 



The species which I have included in this group have forewings 

 deep fuscous or purplish brown ; stigmata either entirely obsolete, 

 or at least the first discal absent. Hindwings as wide or wider than 

 the forewings, rarely (xanthostictella) narrower; costa not or very 

 feebly refuse toward the apex. Only in one species (mandarinella) 

 is the dorsal part of forewing yellow. 



Thus defined, the species may be tabulated as follows: 



Forewings unicolous; no pale spots. 



Thorax unicolorous ; dark brown croceoi crliccl la . 



Thorax not unicolorous. 



With entire ochreous stripe tlioracest rigella. 



With ochreous spot anteriorly \ icinel la.
