var. ii-aiireu/iil " These labels, however, led to a comparison of the 

 description with va ccinii wiXh \y\\\ch it agrees better than with any 

 other American species. But vaccinii is almost the most localized of 

 all of our species so far as now known, being absolutely confined to 

 the summit of Mount Washington and neighboring peaks, and has 

 never been authentically reported below the tree line. U-auremn 

 having been described from a Swedish locality, and the description 

 associating it with i/iterrogafionis, we may safely drop it from our list. 

 This renders it needful to name the species which has so long 

 passed as u-aureiim, for which reason I have nominated it Autographa 

 alias. 



Autographa alias, sp. nov. (PI. VIII, Figs. 7 and 13.) 



This is a species best described by a figure ; even accurate word description of 

 the usual lines, signs and spaces would be almost as applicable to several other closely 

 allied but positively distinct species, the nearest being rectangida (^moyfuorian). 

 Alias is the species which has so long borne the name u-aweiini in American collec- 

 tions, the latter however being quite distinct and nearer to our vaccinii. The pattern 

 is practically the same as in rectaiiqtila. The sign is identical in shape and color, 

 silvery. In a long series before me (twenty-four specimens) there are all gradations 

 of coloration from a suffused form with indistinct lines, and no silvering, except the 

 sign, to a form with sufficient contrast to render the lines, especially the s. t. line 

 quite distinct, a great deal of silvering being present, especially at base of primaries. 

 As rectangula also varies in the degree of silvering, from a form almost all silver to 

 one having very little, it is needful to say that there is never so much silver in alias 

 as in rectangula, and that the space between the t. p. line and the s. t. line is always 

 dark and free from silvering, while in • eciangula the same is always silvery in pro- 

 portion to the rest of the wing. The genitalia are distinct. Expands, 32 to 34 mm. 



Habitat: Common throughout the Northern States and Canada. 

 Type : Male in collection of the author. 



Autographa altera, sp. nov. (PI. VIII, Fig. 9.) 



Allied to octoscripta, which it very closely resembles. It becomes essential, 

 therefore, to indicate the differences. The color of octoscripta is blackish in the 

 darker shadows, grayish in the lighter parts. Usually the darker shades greatly 

 predominate. In altera the darker shades are brown, and the lighter a sort of 

 gray overcast with purplish. The dark and light shades are about evenly distri- 

 buted. The t. p. line in octoscripta is waved, fairly straight, conspicuous, and 

 whitish. In altera it is in longer curves, more bent, very faint and indistinct. 

 The s. t. line in octosci-ipta is black, square at the bend near the apex. In altera the 

 same part of the s. t. line is only slightly extended outwardly and is dentate. The 

 outer border of octoscripta is only slightly paler than the rest of the wing, while the 

 terminal line and fringes are conspicuous. In altera the terminal line and fringes are 

 concolorous with the space without the s. t. line, which thus appears as an outer
