Length of body .82, fore wing .55 inch. Goose Lake, Siskiyou 

 Co., Cal., (J. Holleman). 



It may be known by the S-like third costal spot, the more yellow- 

 ish tint of the under side of the wings, and by the presence of an 

 outer shade on hind wings. The sigmoid spot is much like the bent 

 spot in the middle of the wing in Halia wavaria. 



Acidalia subalbaria n. sp. 1 ?. 



Allied in general form to A. 5-linearia, but with the apex of fore 

 wings much blunter, with the hind wings much shorter, and with the 

 outer edge rounded, instead of angulated. Head and antennae white, 

 front with a broad black band just below the insertion of antennae. 

 Cream colored, being whitish with a very faint ochreous tinge, whiter 

 and less speckled, with darker scales than A. 5-linearia. Primaries 

 crossed by three light brown lines, the basal slightly curved, farther 

 from the base of the wing than usual. The two outer lines much 

 nearer together than usual, the inner one being narrower and less 

 distinct ; both are less oblique than usual, and not waved. Discal 

 dot obsolete. Hind wings with a discal dot, and beyond the two 

 parallel outer lines same as on hind wings. Both wings with a nar- 

 row black line at base of the whitish fringe. Beneath cream white, 

 discal dots distinct on both wings, those on primaries largest ; beyond 

 them a common diffuse dusky line, straight on fore wings. A fine 

 narrow brown line at base of fringe. Legs white, fore femora and 

 tibise blackish in front. 



Length of body .30, fore wing .47 inch. California (Edwards). 



In this species the wings are clearer whitish than usual, especially 

 on the under side, and the two outer lines are nearer together than 

 usual, while the hind wings are shorter, and with the outer edge less 

 convex than usual in those species in which the hind wings are 

 rounded instead of angulated. 



Acidalia rubroliiiearia n. sp. 1 d", 1 ?. 



Closely allied to A. Calif orniaria. Dull reddish ash; the fore 

 wings with four dull brick red wavy lines (three on hind wings). 

 Body and appendages, including legs, a little darker than wings 

 especially on the under side of body, where there are black scales 

 mixed with the brown ones. Palpi stout and bushy, with unusually 

 long hairs. Antennae with long dense cilia? ; beneath black, above 

 pale brown. Wings a little darker at base than externally ; fore 

 ' wings with a basal curved reddish brown line ; an indistinct brown 

 discal dot ; beyond three parallel dull reddish brown wavy lines, the
