Ground color brown. Head and thorax (Miiicolorous, abdomen more 

 fuscous. Priniiiries with the median space brown, the surrounding and 

 marginal spaces whitish to pale brown, often with a blnish or violet 

 shading. Transverse anterior line transformed into a curved white 

 line from base to the internal vein, jilong whicli it is continued to the 

 transverse posterior line, leav^ing all below this line pale, to joiu the 

 l)ale shade beyond the transverse posterior line. Transverse posterior 

 line black, followed by a wdnte line, these lines lost in strongly con- 

 trasting si)ecimens; upright or nearly so, with a usually acute, rarely 

 obtuse, outward tooth over the median vein, and sometimes a more or 

 less marked, never strong, siiuiation thence to the margin. Subter- 

 minal line punctitbrm, a little sinuate, com])osed of winte scales pre- 

 ceded by blackish, somewhat indefinite spots, and beyond this the wing- 

 is again somewhat washed with brown to the margin, darkening to a 

 more or less prominent ol)li<|U(', subii])ical streak or mark, the apex of 

 the paler portion of the wing. The ordinaiy spots are variably defined 

 by upright black scales. Secondaries uniform, smoky fuscous. Beneath, 

 somewhat reddish gray, powdery, with a common faint extra median line, 

 within which the primaries arc dusky; secondaries with a discal spot.

This is more widely distributed than the previously named species 

 and varies a little in ground color within the limits of the same sex. 

 Out of over a dozen s|)ecimens before me none are males, and I am 

 therefore unable to give the sexual variation. There is a distinct vari- 

 ation, however, from an almost white shading extra medially to a faint 

 violet and even brown tinge, all sorts of intermediate forms occurring. 

 The outward tooth of the transverse posterior line also varies some- 

 what in prominence and in the acuteness of its tip. It is upon a rather 

 dark specimen with somewhat broad angle and altogether faded, that 

 Mr. Grote based his species B. jW-inlU. In the wing foriii this species 

 whicli so nearly resembles B. bdlfimoralis in ty])e of marking is quite 

 different from it. The primaries are broad, the (.-osta quite arched, the 

 outer margin broadly outcnrvcd and only a little ol)liquc; the excava- 

 tion below the a^^ex barely marked.

(rround color brown, varying in shade. Head and thorax concolor- 

 ous, variably marked with gray scales. Abdomen of the same shade 

 as the secondaries, the segments narrowly ])ale ringed, most evidently 

 so in the males. Primaries in the females with the basal and extra 

 median spaces more or less prominently white marked; in the male 

 only a little ])aler than the median space, which itself is not so dark; 

 the subtcrniinal space more or less whitish powdered. Transverse
