THE CANADIAN ENTOMOLOGIST 



which seemed to me a unique, was stated by Prof. Smith to be "probably 

 the species Dr. Dyar calls umbrosa." The name, being found preoc- 

 cupied, was changed as above. Prof. Smith tells me he has a specimen 

 from Cartwright, Man., and I have a $ from the same locality, which 

 looks the same. Dr. Dyar's reference oi periunbrosa to cynica rather than 

 to rubifera, is based on the form of $ genitalia. My Calgary specimen 

 is of a rather uniform dark brown, with scarcely any tinge of red or contrast 

 in shades. The t. a. and t. p. lines seem less waved than in rosaria, which 

 it resembles more nearly than anything else in my collection, and the 

 secondaries are dark smoky. Described from Kaslo, B. C. The type is 

 presumably at Washington. 



209. iV. rosaria, Grt. — Fairly common at treacle some seasons. 

 Middle June to middle July. 



210. JV. Calgary, Smith. — Described from here. The type is at 

 Rutgers College. Generally common, rather more so than the preceding, 

 at treacle, during the same period. I used to confuse the two species, but 

 careful study of long series enabled me at last to distinguish them at a 

 glance. In form Calgary differs from rosaria in having less rounded 

 apices ; in maculation in having the terminal area not darker, but usually 

 paler, than the subterminal. In rosaria the reverse is almost invariably 

 the case. Rosaria is of a rosy red colour throughout, whereas the 

 tints in Calgary are brownish red and brownish ochreous. In rosaria 

 the basal t. a. and t. p. lines are almost always double, generally fairly 

 distinct, rarely obsolete. In Calgary, though generally traceable, they are 

 rarely distinct, and still more rarely are any of them double. The t. p. 

 line may be followed by a narrow pale shade, but the outer portion of the 

 line is usually obsolete, or at any rate is not distinguishable from the dark 

 s. t. shade, as it is from the pale s. t. shade in rosaria. The spaces in 

 the cell between the spots and before the orbicular are sometimes black 

 in Calgary, but never in rosaria. I have bred specimens from larvge 

 beaten from sallows in early spring. The $ 9 of hoih. species are 

 smaller than the c^ $ . 



211. N. dislocata. Smith. — (Can. Ent., XXXVI., 149, June, 1904). 

 Described from here from four ^ $ and two $ $ . The type is in Prof. 

 Smith's collection, and a $ co-type is in my own. The description applies 

 for the (^ , which I feel convinced is a good species, but I have no reason 

 for believing that a $ co-type sent me by Prof. Smith, picked from his 



• series of Calgary, is other than that species. It is by no means common,
