Notes on North American Lepidqptera. 9 3 



We are satisfied that Grote aud Robinson's species is iden- 

 tical with A. brumosa. 



The depth of the color on the hind wings has been men- 

 tioned as a sufficient character in separating the species ; but 

 it is variable, as a large series in our collection will show. 



We have specimens from Canada (Prof. F. X. Belanger 

 and Mr. George Norman), from Wisconsin (Prof. S. H. 

 Peabody), from New York (Messrs. Fred. Tepper and E. L. 

 Graef), from the Adirondack Mts. (Mr. F. C. Bowditch), 

 from Mt. Washington, N. H., near the Half Way House (H. 

 K. Morrison) and many from various localities in Massachu- 

 setts. 



The variation in marking and particularly in size is con- 

 siderable. 



Acronycta pudorata, nov. sp. 



Expanse Si mm . Length of body 16 mm . We have had a single speci- 

 men of this species in our collection for a long time, but have hesitated 

 to describe it, fearing that it was but a variety of A. tritona, Hubn. 



The discovery of other specimens of both sexes convinces us that 

 it is distinct. Anterior wings above, bluish gray, with the lines aud 

 dashes as in A. tritona, the ordinary spots are distinct, concolorous and 

 black encircled, in this respect differing from tritona. The posterior wings 

 instead of yellow are pure white with a faint discal dot and median line, 

 followed by a vague suffused terminal band. Beneath white, with conspic- 

 uous discal clots and an angulate median line ; in tritona the ground color 

 is yellowish with scarcely traces of the usual discal dots. 



Habitat. New York ; Canada. 



Specimens received from Messrs. Fred. Tepper and F. X. 

 Belanger. 



M. Guenee's description of A. tritona does not agree alto- 

 gether with Hiibner's figure, and perhaps another species is 

 described by him. 



Agrotis acclivis, nov. sp. 



Expanse 35 mm . Length of body 17 mm . Eyes naked. All the tibise 

 spinose. The antennse of the male with fine short hairy clothing, black 

 above, testaceous beneath. The thorax black above, having a low pro- 

 thoracic tuft tipped with cinereous ; the pterygodes light, and concolor-
