smaller specimen better than it does the larger one, especially as 

 to the sign. However that may be, one of these two specimens is 

 probably the type and the following descriptions are based upon 

 them. 



From these two authentic specimens of Snowi, fifteen specimens 

 of Sackcni from various mountains in Colorado, and nine specimens 

 of diversigna taken at Nordegg, Alberta, by Mr. Bowman, and one 

 specimen received some years ago from Mr. Bean taken at Laggan, I 

 append the following brief descriptions which point out the main 

 characters by which the three species may be separated. 



Snowi. Rich brown of reddish tint. 



Sackeni. Purplish brown. 



diversigna. Brownish purple. 



Snowi. The space between the basal line and the A.T. line is brown, con- 

 colorous above and below the median vein. " At base of costa is an 

 obscure orange streak, bordered with brown." 



Sackeni. The space between the basal line and the A.T. line is mainly yel- 

 lowish above the median vein, and brownish below. The basal line and 

 the A.T. line meet on the costa, the latter passing, sharply oblique, down- 

 ward and then inward. The space between the two lines, and above the 

 vein is more or less filled in with yellowish, and when completely filled 

 forms a distinct sagitate mark. This character, however, is variable. 



diversigna. The space between the basal line and the A.T. line is concol- 

 orous above and below the median vein, slightly olivaceous. The A.T. 

 line begins on the costa distinctly separate from the basal line. 



As a further distinguishing characterization I quote the follow- 

 ing from an incomplete manuscript description of diversigna. 



Autographa diversigna new species. 



The primaries are mainly brownish purple, profusely speckled with 

 microscopic dots, giving the wing, especially in the lighter shades, a 

 reticulated appearance. The median space below the cell is filled 

 with chocolate brown, darkest near the sign and showing the re- 

 ticulation of microscopic dots especially below vein I. 



In Snowi and Sackeni the median space is filled with brown of 

 solid color. 



This new species, Autographa diversigna is described from nine 

 specimens taken by Mr. K. Bowman at Nordegg, Alberta, and one 

 specimen taken by Mr. Bean at Laggan. The type is with the author, 

 also paratypes. Two paratypes are with Mr. Bowman, and one has
