 linear, diseal s]iol. 'i'iie outer line is sliijfbllv ol)rM|iie, nearly parallel svitli IIk^ 

 outer edge, with a deep reijular enrve inward lietwcen the iii'sl median 

 venule and the sui)niediau I'old. This line is usually siiaded with dark or 

 reddish-hrow 11 on the inside, and sometimes the entiin' middle ol'ihe wint^ is 

 dark brown. IJeyond the c.xtradiscal line, the wintr !■< paler and clearer, 

 sumetinK's the strigic arc collected into a iiiint, diU'use, snhmarginal hand. 

 Hind wings a little paler than the anterior pair, with a whitish exiradiscal 

 line, shaded with dark scales on the inside, and curved outward in the suh- 

 mediaii s[)ace. JJeyond this line near the inner angle are scattered dark 

 specks, sometimes forming a short, diil'use l)and. Along the edge of the. 

 wing arc five distinct l)lack dots, becoming larger toward the inner angle; 

 the tit'th one is situated just in i'ront oi' the largest tooth in the middle of the 

 wing. Beneath. i)o1h wings nniforndy reddish or umber-brown, with no 

 lines. TIh; diseal dot on the ihvv. wings is twice as larg(! as on the hind 

 wings, white, couspicnous ; ou the hind wings are faint traces of the c.xtra- 

 discal liiH', especially apparent toward the inner edge. The diseal dot is 

 large, oval, black, edged with white. The marginal black dots are present, 

 beneath.

 This species is very variable. Li the Eastern States, it is often uudjcr- 

 brown as well as reddish-brown. The Pacific-coast specimens are larger 

 than the eastern (the fore wing of a Californian male measuring 0.90, of a 

 Massachusetts male 0.75 inch). The two Santa Barbara males are smaller 

 than usual in Pacitic-coast specimens, and paler, and seem to be distinct from 

 A. behrennata.
