Trenton Falls, N. Y., the same locality as 7ibnbosa. The male antennae 

 are minutely serrate-fasciculate, and strongly bristled. The serrations are 

 less coarse though more distinct than in jiimbosa, mystica or discalis^ 

 and the bristle longer than in the two former, discalis having none. I have 

 it from Montreal ; Biddeford, Maine ; several Manitoba localities, and 

 Red Deer River, near Gleichen, Alta. It seems much less common here 

 in the hills, though 1 took a couple in the Upper Columbia valley, near 

 Windermere, B. C. ' Rogenhoferi Moschler, as catalogued by Sir George 

 Hampson, has male antennae ciliate only. He had no specimens under 

 the name in the collection, but figures as such a male from " W. 

 Manitoba" in Prof Smith's collection. This specimen I have examined. 

 The label is, I think, in Mr. Hanham's writing, and the " W" probably 

 stands for Winnipeg. When I saw it, it had a small piece only of one 

 antenna, which my notes say were " ciliate, with joints little marked." It 

 is something distinct from imbrifera, which I have often received under 

 the name, and a species unfamiliar to me. Prof. Smith, in his Monograph 

 of Mamestra, states that he has examined the male type from Labrador in 

 Mr. Moschler's collection, and that " the antennal joints are distinctly 

 serrated, and furnished with bristly tufts." (Pr. U. S. N, M., XIV, 204, 

 1891.) This leaves some doubt as to the correctness of the identity of the 

 Rutger's college specimen. 



284. The single specimen which t recorded under this number as 

 juncimacula is probably a variation oi ptirpiirissata Grt. It is, however, 

 extremely like Holland's figure oi juncimacula, stated in the text to occur 

 in Colorado, which is therefore presumably the locality of the specimen 

 figured. Sir George Hampson's figure of a Colorado female is much more 

 like the form described by Dr. Dyar from Kaslo as van crydina (Can. 

 Ent., XXXVI, 32, 1904). Hampson lists crydina as a synonym of 

 purpurissata, but had no Kaslo specimens in the collection. Prof. 

 Smith, in Journ. N. Y. Ent. Soc, XV,- 152, 1907, claims that crydina is a 

 good species. I thought that might be so at one time, but after studying 

 more material I find that the Kaslo form, as stated under the description, 

 intergrades with ç.2.?>\^x\\ purpurissata, which is the predominating form at 

 Calgary. The type oi juncimacula Smiih, is a male in the Washington 

 collection, bearing no locality label. Neither, by the way, is the labelled 

 •' type " in Prof. Smith's handwriting, though bearing the Museum red 

 type label. I have not seen the description, bat the form appears to have
