with the thorax. Wings of a unifonii snuff-brown, speckled inimitely with 

 l>lafk, especially along tlie costa. No basal line on fore wing; a prominent 

 dusky, diffuse, wavy, extradiscal line, obliciue, a little sinuate, parallel with 

 the outer edge of the wing; half-way between this and the base of the fringe 

 are two indistinct lines, the inner one more distinct and very wavy; a narrow 

 dark line along the base of fringe, w hich last is clear snuff-brown. A mar- 

 ginal row of distinct, minute, black dots. A fiiinf brown discal dot. The 

 same lines are repeated on hind wings. Beneath, scarcely i)aler than above, 

 witli the extradiscal line ])lack and very distinct, tiner than on the upper side; 

 the two other lines very faint, the inner one, however, in some specimens, 

 quite distinct and very wavy. A marginal row of small black dots; the base 

 of both wings is thickly speckled with l)lack scales. 



Length of body, 0.y5; fore wing, 0.35-0.46; expanse of wings, 1.00- 

 40 inch. 



Mendocino City, Cal. ; 8an Mateo, Cal. (A. Agassiz) ; SanzaUto, Cal., 

 May 6 (Bchrens); California (Edwards); mountains of Colorado, July 22 to 

 August 29 (Lieutenant Carpenter) ; banks of Blue River, Middle Park, 

 elevation from 9,000 to 10,000 feet (Mead): Colorado (Mr. Ridings). 



Having received more specimens from Mr. Edwards, I find that A. 

 jxicijicaria is simply a variety of californiaria, differing in its smaller size, 

 the more rounded apex of the fore wings, and the less oblique outer border. 

 The extradiscal line is blacker than usual and much less oblique, with a bend 

 inward below the median vein. Discal dot distinct, Iffack. Near the outer 

 edge is a pale, clear, irregular, scalloped line parallel to the outer edge, and 

 diminishing in width toward the costa. It is as common apparently in Cali- 

 fornia as its repre.sentativ<;, A. indiicfuta, is in the States east of the Rocky 

 Mountains.
