thorax. Wings of a uniform snuff brown, speckled minutely with 

 black, especially along the costa. No basal line on fore wing; a 

 prominent dusky, diffuse, wavy extradiscal line, oblique, a little sinu- 

 ate, 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 

 most distinct and very wavy; a narrow dark line along the base of 

 fringe, which last is clear snuff brown. A faint brown discal dot. 

 The same lines are repeated on hind wings. Beneath scarcely paler 

 than above, with the extradiscal line black and very distinct, finer 

 than on the upper side; the two other lines very faint, the inner one 

 however, in some specimens, quite distinct and very wavy. A mar- 

 ginal row of small black dots ; the base of both wings is thickly 

 speckled with black scales. 



Length of body, .35-.40 ; fore wing, .40-.46 inch. Edwards. 



A. Paeifiearia n. sp. $, 9. 



Closely allied to the preceding, but differing in its smaller size, the 

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

 The extradiscal line is blacker than in the other species, and much 

 less oblique, with a bend inwards below the median vein; discal dot 

 distinct, black. Near the outer edge is a pale, clear, irregular, scal- 

 loped line parallel to the outer edge, and diminishing in width towards 

 the costa. A marginal row of distinct, minute, black dots, not present 

 in the other species, and the wing is more dusky at base. Beneath, 

 the two outer lines are nearly equally distinct, the outer one waved; 

 hind wings much as in A. Calif orniaria. 



Length of body, .34; fore wing, .35 inch. Edwards. 



Acidalia rubromarginaria. $. 



Brown, with a reddish tint. Body and base of both wings ferru- 

 ginous dull brown ; both wings dull reddish brown at base ; on fore 

 wings this tint extends to a little beyond the middle of the wing, its 

 outer edge irregular, angulated in the middle and excavated below. 

 It is crossed just before the middle of the wing by a slightly oblique, 

 dark line, on which rests an irregular row of light brown scales; be- 

 yond the wing is a clear tawny brown, with a submarginal line 

 curved and slightly waved, made up of black dots on the venules 

 connected by a slight line ; this line is parallel with the outer edge 

 of the basal dark area. A marginal row of black dots; fringe deep 

 brick red. Hind wings the same, but the dark portion at base only 

 extends to first third of wing, and the broken wavy curved line of
