A^rERICAN LEPIDOPTERA. 17!) 



from the extreme base of the wing below the median nervure. Above 

 this streak, and margined outwardly by the basal half line, the extreme 

 costal base of the wing is pale glaucous cinereous. Between the basal 

 half line and the transverse anterior line the wing is dark cinereous 

 and is traversed by two opposed and subobsolete transverse, waved, 

 shaded lines, becoming tinged with reddish-brown before internal mar- 

 gin, the latter edged within, before the t. a. line, with a distinct black 

 line following the shape of the wing. The t. a. line is geminate, regu- 

 larly but shallowly waved, the outer of its two component lines the 

 darker, and becoming black below median nervure. Inferiorly, and 

 preceding the t. a. line, the wing is diffusely stained with pale, clear 

 reddish-brown. Costa marked with alternate whitish and dark cine- 

 reous streaks, the darker of which seem to form the inception of obso- 

 lete transverse shade-lines. Median space, dark cinereous; below the 

 median nervure, an oblique, diffuse, outwardly directed, pale glaucous 

 cinereous shade-patch, which extends across t. p. line, and is limited 

 externally by the black subterminal shade. A narrow black curvili- 

 near streak on the disc ; a second, moi-e broadly marked, is continued 

 below the median nervure outwardly to the black subterminal shade. 

 Beyond the discal streak, the wing is stained again with clear pale red- 

 dish-brown. The transverse posterior line is geminate, rather faintly 

 marked and very irregular. It margins inwardly and obliquely the costo- 

 apical whitish patch, as in the male, is medially produced, thence run- 

 ning backwards below the second curvilinear black streak, constricts 

 the median space inferiorly and joins internal margin before the angle. 

 A deep black subterminal shade-line, preceded by a diffuse black shade, 

 which is broadest opposite the disc, and is cut by unequal deep black 

 sti'eaks betAveen the nervules. A slight oblique blackish, apical streak. 

 The conformation of the subterminal shade remind.s one of certain spe- 

 cies of the genus Parorgi/ia. The narrow terminal space is of an even 

 dark cinereous, the nervules here touched with whitish scales. A nar- 

 row terminal line, interrupted at the nervules, lunulated over the in- 

 terspaces, accompanied with olivaceous scales. The extreme edge shows 

 an obsolete dark line. Fringes, dark cinereous, interrupted with black- 

 ish at the extremity of the nervules. Beneath, cinereous, without de- 

 finite markings; centrally, with longer hair-like scales; at base and 

 along internal margin, whitish; the black subterminal line and shades 

 of the upper surface are here reproduced, accompanied by the apical 

 and interspaceal streaks ; terminal space, clear grey. Secondaries, 

 blackish, thus contrasting forcibly with the white hind wings of the
