the inner margin at about its middle. In the male the two lines are 

 equally distinct, and are smoky, the intervening spaces of the ground 

 color. In the female the line is broken, and sometimes disappears 

 almost entirely, the outer portion being often represented by a dot in 

 the middle of the wing, and a dusky blotch on the costa and inner mar- 

 gin. The transverse posterior line is black or blackish, lunulate, well 

 removed outwardly, strongly incurved below the cell, and thus bisinu- 

 ate. The black lunules are preceded by a whitish shade and also, oppo- 

 site the cell and in the submedian interspace, by a smoky mark. The 

 line is followed by a dusky shade, which merges insensibly into the 

 ground color. Subterminal line wanting. There is a series of black 

 or smoky terminal spots in the interspaces, which may or may not cross 

 the fringes. In the female all this marking is obscured; but on the 

 other hand there is a vague, smoky, almost upright median shade, 

 which darkens the reniform and forms a smoky blotch on the inner 

 margin. The ordinary spots are distinctly outlined in black in the 

 male, but vague and partly obscured in the female. The orbicular is 

 round and usually small, sometimes minute; the reniform is large, 

 kidney shaped, and has a smoky central mark which, in the female, 

 obscures the entire spot. There is no basal streak, and only a poor 

 indication in some specimens of a dagger mark opposite the anal 

 angle, an outward tooth of the transverse posterior line, which is here 

 usually best marked, giving the appearance of a small dash. The 

 secondaries are whitish, a little soiled in the male, strongly gray pow- 

 dered in the female, in which there is a more or less obvious, diffuse, 

 outer smoky band. The veins are smoky, and there is a traceable 

 discal lunule. On the under side the wings are whitish in the male, 

 smoky in the female; in both sexes with a discal lunule and in the 

 female also with a diffuse outer shade line. The head and thorax are 

 without marks of any kind, save there is a blackish mark between the 

 eyes and the base of the wings in some specimens. The sides of the 

 palpi are also black.

Two males and six females are before me, nearly all of them in fair 

 condition. The Californian specimens are probably from the Sierra 

 Nevada Mountains, but I have no definite data concerning them. 

 Types are in the U. S. National Museum, the American Museum of 

 Natural History, and in the collections of Messrs. Graef, Dyar, and 

 Doll. This species is intermediate in most respects between hastulifcra 

 on the one hand and dactylina on the other. It has most the appear- 

 ance of dactylina and has been mistaken for that species. It is probably 

 not at all rare, and replaces (Inctylina in the Northwest. Where a 

 series of speidmeus can be compared theie is no difficultj^ at all in 

 recognizing the distinctness of this species. It is larger, in the first
