132 THE CANADIAN ENTOMOLOGIST 



376. 0. euroa G. and R. — Grote changed the name to puta, 

 to which Sir George Hampson gives preference. The two names 

 therefore apply to the same type, but I have not discovered where 

 that type is to be found. Presumably it ought to be in the collec- 

 tion of the American Entomological Society at Philadelphia. 

 Smith described dusca in Ann. N. Y. Acad. Sci., xviii., 117, Jan. 

 1908, from Cartwright, Miniota and Winnipeg, Man., and Kaslo, 

 B.C. I have seen a male and female type from Brandon and 

 Miniota, and the type labels bear this name. But in an earlier 

 paper (Trans. Am. Ent. Soc, xxxiii., pp. 350, 360), he makes refer- 

 ence to the form as duscata. Compared with euroa, it was stated 

 to be "smaller, darker, with more diffuse maculation, and with 

 shorter, broader primaries." Genitalic differences were referred 

 to in the "Transactions." Calgary specimens do not differ from 

 those from Manitoba, and Smith would obviously have called 

 them dusca. As a whole, the species is perhaps usually smaller 

 and darker in the west, but not constantly so, and I can see no 

 reason whatsoever for treating the western form as distinct, and 

 must refer dusca to the synonymy. Dr. Barnes told me some time 

 ago that he was of the same opinion. 



377. Agroperina lineosa Smith. (Journ. N. Y. Ent. Soc, xviii, 

 145, Sept. 1910). — Described from thirty specimens from Calgary 

 and several Manitoba points. Pendina Smith, described as a 

 species from the same localities in the same paper, is unquestion- 

 ably a variety of the same thing, and is almost that form I referred to 

 as "dark crimson." I have such an extreme form, but "deep luteous 

 red-brown," as Smith describes it, is a more common variation 

 and this is the"morwa, ab. 2, deep rufous," of Hampson's Catalogue, 

 vii., 405, his "ab. 1" being a pale rufous form, intermediate be- 

 tween the more common luteous lineosa and var. pendina. The 

 actual specimen figured by Hampson as mama, from Yellowstone 

 Park, Wyoming, is of the pale uniform, slightly marked form de- 

 scribed by Smith in the same paper, also as a species, as indela, 

 from various localities in Wyoming, Idaho, Colorado, Montana 

 and Washington. The morna of Strecker, as I have pointed out 

 under my No. 155 (xliii, 230, July, 1911), is not allied to this group 

 at all. By Smith's own admission, indela and lineosa were very 

 difficult to separate, and from the material I studied in his collec-
