which respect it is like vai-iinii, which is found nowhere except above the tree line in 

 the White Mountains. On the contrary, I have exceh'i from the White Mountains 

 and from Laggan, British Columbia. In angididens there are strong contrasts of 

 coloration, the lines showing distinctly against the lighter grayish shadows. In 

 excelsa the color scheme is a suffusion of two shades of brown. In regard to color, 

 the two species separate just as californica differs from the European gamma. Per- 

 haps the surest superficial guide by which to separate excelsa from angididetis will be 

 by the sign. In both it may be either white or golden. In angulidetis the inner sign 

 is like the letter U, lying slightly obliquely, the open ends curving inwardly. In 

 excelsa this part of the sign is rather V-shaped, a slight inward crook however occur- 

 ring on the end of the outer branch of V. The outer dot may be large, small or 

 absent from either species. Excelsa is smaller than angididens, the latter expanding 

 36 mm., the Laggan examples of excelsa reaching only 30 mm. A New Hampshire 

 specimen (female), however, reaches 34 mm. in size. 



Habitat : Northern United States and Canada. 



Type : Female, with the author. 



The type was taken by the author in Jefferson, N. H., with others 

 like it, which have gone to other collectors as angulidens. One is 

 with Mr. Thaxter. Three others before nie are from Laggan, and 

 I have seen a great many more from that locality, all very much 

 smaller than angulidens which seems quite uniformly large. I should 

 mention that the genitalia of the two species differ. 

 Autographa celsa Hy. Ediu. (PI. VIII, Fig. 4.) 



My material identified by comparison with type in Neumoegen 

 Collection, Brooklyn Institute, and with type in Edwards Collection 

 American Museum of Natural History. 

 Autographa selecta Walk. (PI. IX, Fig. 7.) 



Selecta Walk., and viiidisignata Grt., are both represented by type 

 in the British Museum and material sent there for comparison is returned 

 bearing the two names, G rote's name, the better of the two, unfor- 

 tunately passing into the synonymy. I feel obliged to call attention 

 to a fact in relation to the sign, in spite of what I have said of its 

 slight value. Grote describes the sign as " a peculiar greenish-golden 

 hue — verdigris-like." I have one specimen to which the words 

 "peculiar-greenish-golden," seem most applicable. Four others are 

 green. I once had a wreck of this species sent to me in an envelope. 

 The two primaries however were in sufficiently good condition for 

 identification (for which purpose the specimen had been forwarded) 

 and the sign was quite golden. The variation then would seem to be 

 from green to gold through the various intermediate stages. It is a
