scales edged with brown. Fore wings with five well-marked lines, the 

 two basal approximate, parallel, and as well marked, as are all (lie others, on 

 the ensta, both slightly curved, oblique, and dislocated on the submedian 

 vein; discal spol distinct, sublinear; the third line bends around outside it, 

 lull very near it, and nearly touches the fourth line just below the median 

 vein; sometimes this is a broad, dark band (B. dendraria Guen.); fourth line 

 a regularly and deeply scalloped band, inclosing a white, similar line, blackish 

 within, brown outside the white line, bent at, right angles on the first median 

 vein, thence curving around and ending beyond the middle of the inner edge; 

 the tilth (ami submarginal) is a dentate white line, parallel to the outer edge 

 of the wing, the scallops tilled in with blackish, the broad black band inter- 

 rupted on the first median interspace: a marginal row of linear black lunules. 

 Hind wings with no basal band; just before the short, lunate, discal dot, a 

 diffuse brown shade (in var. dendraria broad and black and confused with the 

 median scalloped line); middle line blackish, scalloped, edged externally with 

 white, with a brown shade beyond; submarginal line as in the fore wings; 

 marginal lunules long and linear. Fringe concolorous with the wings in both 

 pairs. Beneath, with a taint testaceous tinge. Costa of the fore wings 

 checkered with six black, square spots. The second and fourth lines repro- 

 duced quite distinctly; the fourth also present on the hind wings A broad, 

 dusky, submarginal shade on the fore wings, growing more distinct on the 

 costa. Abdomen with two rows of black dorsal dots. Fore legs brown, 

 with paler rings. Hind legs pale. In the female, the lines are not so well 

 marked as in the male, but otherwise it does not differ. 



Length of body, cJ,0.80, 9,0.75; of fore wing, J, ].10, 9, 1.15; expanse 

 of wings, 2.15 inches.

This splendid moth may be known by its large size, the broadly pecti- 

 nate plumose antenna', the fine, nearly straight lines on the fore wings, with 

 the fourth bent once at right angles. It is the largest species of the group 

 in the United Stales. 



Guence's 11. dendraria is evidently represented by one of my specimens 

 from North Carolina, in which the third and fourth lines are broad, confused,
