frass, wliieh has been deposited along the edges of the mine, is col- 

 lected and made into an oval ring-like wall of the cocoon, leaving 

 the cuticle transparent, through which the pupa is plainly visible. 

 It ranges throughout the entire United States. Specimens collected 

 by Lord Walsingham in California and Oregon (of which there is 

 a specimen in the U. S. Nat. Mus.) are identical with the eastern 

 specimens, but somewhat larger and the white streaks are a little 

 broader and more distinct.

 "Face, palpi and under surface silvery white, the under surface and legs 

 tinged with yellowish ; antennae silvery, annulate above with dark brown. Tuft, 

 thorax and anterior wings saifron yellow, with a white patch in the center of 

 the tuft and the usual white line across the anterior margin and sides of the 

 thorax, which, however, as in other species, is sometimes wanting. When pres- 

 ent it is confluent with the rather long narrow median basal white streak, which 

 is faintly dark margined towards the dorsal margin. Just before the middle is 

 a white fasciH, augulated near the costa and produced backwards at the angle, 

 and strongly dark margined internally. Near the base of the cilia is another 

 straight white fascia not definitely bounded, anteriorly margined with dark 

 brown and with many dark brown scales intersjiersed in the white, and some- 

 times divided into two or three rather indefinite sjiots. The apex of the thorax 

 is white, and from it a narrow white line passes along the posterior margin of 

 the wing to the first fascia, and sometimes is faintly indicated to the base of the 

 cilia and is margined with dark brown. Apex dusted with dark brown on a 

 white ground, the dusting margined by an oblique white line internally. Some- 

 times the dusting is not thick, and the whole apical half of the wings is sparsely 

 flecked with dark brown scales. The markings of the apical half of the wing are 

 all indefinite, the colors not being separated by distnict well-marked lines, but to 

 some extent running into each other. Alar expanse less than one-fourth inch. 

 Kentucky. Very abundant. There is some variation in the intensity of the 

 color, some species being much paler than others, and one specimen in my pos- 

 session has the thorax entirely white." 



In the original description, which is reprinted above, Chambers 

 says that the basal streak is "faintly dark margined toward the 

 dorsal margin." In all my specimens (bred), the streak is mar- 

 gined toward the costa and not at all on the dorsal side. The first
