In some specimens is a subapical row of two or three round black spots. 

 Discal dots either distinct or obscure, and almost obsolete. Mr. Walker's 

 type is not in the British Museum ; i)ut his description, l)rief as it is, applies 

 well to this species.

This species is one of the larg(!st of the genus, and, though exceedingly 

 variable, may usually be determined by the very deeply serrate wings, by the 

 rusty-ochreous hues, the irregular, dentate, not very distinct lines, and l)y the 

 ochreous under side, mottled, however, with rust-brown. While in the form 

 of the wings it is much like serrafaria, in coloration E. ohlusurid is more likfdv 

 to l)c mistaken l()r the titrmer. I append the description of an unusual form 

 from Illinois : 



1 <^ . — Fawn-color, with difl'use dark-biown bands; beneath, with an 

 ochreous tinge. Body flnvn-color like the wings; a broad, diU'use, curved, 

 l)asal band (often obsolete); a similar mesial band not much curved, crossing 

 the site of the discal dot, which is obsolete. The outer line is broad, ditFuse, 

 dark brown, becoming paler externally; it is straight to just befon; the costa, 

 where it curves, though it is not angulated; between the inner and outi-r 

 lines the wing is tinged with ochreous ; beyond th(; outer line the border is 

 lawn-colored, with dark strigaj ; edge more ochreous, fringe darker. An 

 apical oblique dark streak, concolorous with the three lines ; edge of the 

 wing scalloped slightly, apex very acut(dy produced. Hind wings deeply 

 indented, both acute, tinged with ochreous within the outer line; beyond, 

 lawii-color, with more numerous and distinct striya' than toward the base of
