7 S and 8 9. — Palt- asli, witli dense l)n)\vn scalc.-^, or white, with fine 

 diisliv scales. Head deep yellow, paler in some ; in one female, while. 

 Body, ineludini;' abdomen, white ; legs dusky externally. Fore wing crossed 

 1)V two Ijlack lines, clearly cut in the white examples, difl'use on one side in 

 dark spt.'cimens ; fhcir distance apart varies greatly; in two closely-allied 

 I'cmale individuals, the lines vary in lieing separated by u distance equal to 

 hall' the length of the wing, while in the others they touch just below tln^ 

 niediaLi vein. The inner line consists of four scallops, the t()urth and lowest 

 half-lormed; the first or costal is often indistinctly marked ; discal dots dis- 

 tinct, larger on the fore wings than on the posterior pair. Outer line sinuate, 

 scalloped, with a great curve outward between the subcostal and the third 

 median venule. Opposite the discal dot are three acute, smaller scallops, all of 

 e(pial size. Fringe whitish, distinctly checkered with black on the ends of 

 th(^ venules. Hind wings with a scalloped outer line, often obsolete toward 

 1li<.> costal edge, varyingin its distance from theouter edge. Beyond this line, 

 the wing is diirker th:iu al 1 he base. Beneath as above, Init sometimes a 

 little clearer.

This delicate pretty moth may be known by the three equal, acute, 

 small teeth opposite the discal spot. It varies much in color, some being 

 snu)ky-ash and densely scaled, others being almost snow-white and with 

 very tine specks. 



Th(^ form whicli I described i\s pel/ucida/ia is a rather larger and more 

 dusky, smoky pellucid form than usual. Head white, front a little dusky ; 

 palpi dark. Thorax ami body j)ale mouse-colored. Wings of the same hue. 

 Inner line not so much curved, and outer line much as usual, l>ut with the 

 three teeth a little longer and less even. The lines are duller, and do not 

 contrast so much with tlie rest of the wing as in tlie ordinary form. Fringe
