T. subcessaria^ l>ui the lines proceeding from them more distincl and con- 

 tinuous. The second spot edged with blackish externally in thediscal space, 

 and the line plainly continuous to the inner edge of the wing. A broad, 

 dusky, chocolate, marginal shade, disappearing before reaching the apex. 

 Fringe faintly checkered with whitish opposite the marginal dark dots. 

 Beneath, both wings decidedlj tinged with ochreous, especially the cost a of line 

 wings and entire surface of hind wings. Discal dots large, diffuse on both 

 wings. The costal spots and lines faintly reproduced as smoky diffuse lines. 

 A faint diffuse line on each side of discal dot on hind wings, not visible above. 

 Fringe faintly checkered with whitish, not so distinct and broad as in T. sub- 

 cessaria Legs ochreous, spotted with brown.

This species, apparently imported from Europe, differs from our native 

 subcessaria by the three scallops on the hind wings, the more broadly-pecti- 

 nated antennas, the chocolate-color of the fore wings, and the yellowish under 

 side of both pairs. In one female, from Philadelphia, the wings are unusually 

 white, and the lines much heavier than commonlv the case; the two inner 

 ones not interrupted, while the outer is continuous from the inner edge to the 

 third median veinlet.

2 <? and 2 9 — Antenna- slightly pectinated; fore wings with the apex 

 obtuse, less produced than usual: hind wings rounded, scarcely bent in the 

 middle, or distinctly scalloped. Body and wings white, with scattered dark 

 speckles. Head dull-whitish ; palpi and prothorax brown. Fore wings with 

 four well-marked costal spots, of which the subapical is snuff-brown, while 

 the others are blackish. The basal is small, triangular, followed by a series 

 of dark, small, venular dots. The second is oblong, with square edges, and 

 not curved as in T. wavaria; it extends to the median vein and is succeeded 

 by a few dark obscure venular dots. The three costal spots are of tin- same
