T. suhcessaria, but the lines proceeding from them more distinct and coa- 

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

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

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

 Fringe faintly checkered with whitish o[)[)osit(! the marginal dark dots. 

 Beneath, both wings decidedly tinged with ochreous. especially the costa of fore 

 wings and entire surface of liind wings. Discal dots large, ditfuse on both 

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

 A taint difluse 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. suh- 

 a'ssaria. Legs ochreous, spotted with brown. 



Length of body, <? , 50, 9, 0.45; of fore wing, S, 0.(52, 9, 0.62; ex- 

 panse of wings, 1.25 inches.

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

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

 nated antennae, 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 commonly the case; the two inner 

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

 third median veinlet.

2 S ami 2 9 — Antennfle 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 arc blackish. The basal is small, triangular, followed bv a series 

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

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

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