Psedisca radicana. (Plate LXXII. fig. 5.) 
Headj palpi, and tliorax brownish fuscous, palpi extending scarcely more than the length 
of the head beyond it, thickly clothed ; apical joint not exposed : antennse brownish. Fore 
wings — rather more than twice as long as wide ; the costa arched ; apical margin oblique, 
slightly convex; the costal fold in the male closely appressed — the ground-colour creamy 
white, much mottled and suffused with grey ; a greyish basal patch covering about one third 
of the wing, including on its outer edge a brownish-fuscous band, which becomes obsolete 
towards the costa ; about the middle is a ferruginous-brown fascia, angulated on its outer 
edge below the costa, dotted with fuscous, and crossed by a fuscous line below the middle ; 
the apical portion of the wing is also ferruginous brown to a point above tlie anal angle, and 
is internally mottled with fuscous ; a small fuscous wedge in the pale ground-colour before 
the middle of the dorsal margin : cilia dull grey. Hind wings fuscous brown. Legs fuscous, 
spotted with ochreous. Underside of fore wings brownish fuscous ; the costa spotted with 
ochreous ; underside of hind wings yellowish white, spotted with pale fuscous. Expanse of 
■wings 15 millims., $ 13 millims. 
Rouge River, Oregon, May 1871. 
Psedisca abruptana. (Plate LXXII. fig. 6.) 
Head brownish ochreous, thickly tufted above ; the palpi ochreous, tipped witli fuscous, 
short and obtuse ; the fuscous apical joint scarcely exposed; antennse ochreous. Fore wings — 
with the costa arched, an appressed costal fold at the base — much mottled with various shades 
of ochreous brown and fuscous ; a patch of fuscous scales about the middle of the wing on 
the basal third ; some oblique slender geminated whitish costal streaks, those nearest to the 
apex forming a triangular spot ; below this, arising in the apical margin, is an elongated 
Avhitish spot, joined to the third pair of costal geminations by a slender grey and fuscous line ; 
the ocellated spot is subochreous white, with shining scales on its inner and upper external 
edge, and a minute fuscous spot at its upper extremity : cilia whitish, irrorated with fuscous. 
Hind wings and cilia dull brown. 3 J* . Expanse of wings 15 millims.

I have little doubt that this is the species referred to by the late Dr. B. Clemens in the 
' Proceedings of the Entomological Society of Philadelphia,^ vol. v., where, after describing 
his Steganoptycha fluvoceUana from a specimen in his own collection, he mentions that there 
are other specimens from Yirginia, in the collection of the Entomological Society of Phila- 
delphia, of which the general hue is paler, and which are not more than half the size of the 
specimen chosen as his type. I have myself seen in that collection specimens of the species 
now under description labelled Stegmioptycha flavocellana, Clem.; but I am assured by Prof. 
Fernald, who has seen Dr. Clemens^s type, that the present species is quite distinct from it. 
The absence of a black central dash, and of one on the costal edge of the ocelloid spot, 
are among the most noticeable points of divergence from Dr. Clemens^s description, in which, 
unfortunately, the dimensions and the presence or absence of a costal fold are not referred to.
