AMERICAN LEPIDOPTERA. 851 



cinereous; collar with a narrow dark line. Antennae slender, black- 

 ish, slightly thickening to base. Labial palpi divaricate, the second 

 joint rather thinly scaled, concolorous with the head. The under tho- 

 racic squamation is rather loose and long, pale olivaceous cinereous. 

 Abdomen cinereous; a few blackish scales above at anus. 



Anterior wings rather long and narrow, silky in certain lights, dark 

 olivaceous cinereous or blackish, concolorous with the head and tho- 

 rax above. Ordinary lines black and narrow. IJasal half-line and 

 transverse anterior, geminate. The first dentate, its inner line distinct, 

 its outer faint ; the space enclosed by the two is pale. The transverse 

 anterior is slightly outwardly oblique and thrice-waved; it is distinctly 

 marked on costa, but below this its inner line becomes obsolete, but 

 the distinct outer line is preceded by a narrow pale coincident and 

 faint shade, analogous to that contained by the basal half-line. Ordi- 

 nary spots moderate, concolorous with the wing, with very narrow 

 black annuli which are unequally marked. Orbicular rounded ; reui- 

 form of the normal shape, faintly stained inferiorly with darker scales, 

 with an indistinct internal aunulus. Median shade distinct, especially 

 superiorly, outwardly projected, edging the reniform spot inwardly on 

 the cell ; inferiorly it spreads slightly outwardly on the veins. Trans- 

 verse posterior line faint, less distinct than the median shade; at its 

 inception, above the reniform spot on costa, it is geminate, being pre- 

 ceded by a black mark ; elsewhere it is single, slightly inwardly arcu- 

 ated between the veins, regular and but slightly projected ; the dark 

 scales extend slightly beyond it on the nervules. Three pale dots on 

 costa before the narrow irregular subtermiual line, which is faint and 

 pale, preceded by a diffuse dark shade resolvable into interspaceal sa- 

 gittate marks. A very narrow, black, interrupted terminal line. 

 Fringes but little paler than the wing. Secondaries pellucid, silky, 

 whitish, with a cinereous tinge which deepens externally, becoming- 

 very determinate along external margin without forming a limited bor- 

 der. The veins are marked with dark scales ; no discal spot or trans- 

 verse line ; fringes white or whitish. Beneath, the primaries are dark, 

 unicolorous, but little paler than on the upper surface, glossy; faint 

 traces of a blackish transverse line, discontinued inferiorly. Seconda- 

 ries whitish, powdered with cinereous scales which are gathered into a 

 broad terminal band, obsoletely limited inwardly by darker scales on 

 the veins ; no discal streak ; fringes as on upper surface.
