Psedisca radicana. (Plate LXXII. fig. 5.) 



Head, palpi, and thorax 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 the 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.

Psedisca abruptana. (Plate LXXII. fig. 6.) 



Head brownish ochreous, thickly tufted above ; the palpi ochreous, tipped with fuscous, 

 short and obtuse ; the fuscous apical joint scarcely exposed ; antennae 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 

 whitish 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 flavocellana from a specimen in his own collection, he mentions that there 

 are other specimens from Virginia, 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 Steganoptycha 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.
