THE CANADIAN ENTOMOLOGIST. 



from an unknown locality, and two from Sudbury, Ontario, which are the 

 only eastern specimens which I possess. However, I see no differences 

 that I should suspect of being specific. Cartwright and Miniota specimens 

 in my collection are alike, and probably more typical cervina than those 

 from Alberta, being a litile smaller and darker. Tœniocampa suffusa 

 Smith, type, is an Arizona female in the Washington Museum, and 

 appeared to me to be a pale lusiralis, and is referred to that species by 

 its author in his Check List. 



^289. M. segregata Smith. 



(290. var. gussata Smith. — I am convinced that these two are the 

 same species. Dr. Dyar suggests in the Kootenai List that gussata is 

 only a variety of segregata, and I agree with him. Gussata is less highly 

 coloured than segregata, and has more black markings. In my former 

 notes I stated that Sir George Hampson considered the two to be the 

 same species. That was his opinion expressed in a letter to me about 

 that time. Before publishing, however, he altered his opinion, as he 

 places segregata in the genus Polia, and gussata in Hyssia, separating 

 them in the Catalogue by 136 pages, and figures a Calgary specimen 

 under each name. Prof. Smith, in Journ. N. Y. Ent. Soc, XV, 156-7-, 

 Sept., 1907, closely analyzes Hampson's descriptions oi Polia and Hyssia 

 and points ont that there is no tangible difference except a very doubtful 

 one of abdominal tufting. At the same time, he makes no suggestion 

 that segregata and gussata are the same. 



291. M. negussa Smith. — A series received from Redvers, Sask., 

 from Mr. Croker, is very constant, which fact, in this genus, I accept 

 as evidence in favour of distinctness from segregata, which the form 

 resembles in almost every respect, only entirely lacking all black markings. 

 Hampson places it in Folia, and figures a Calgary specimen di^ plicata, of 

 which he makes it a synonym. The figure is bad, and too contrasting. 

 He mentions in his description that the discoidal spots are defined by 

 black, which is not the case in any of my Calgary or Redvers specimens. 

 The male type oï piicata from Glenwood Springs, Colo., has the spots 

 outlined in black, and a black basil streak, agreeing in these respects 

 with my only specimen from that locality, a female. Negussa is also 

 slightly smaller, but whether really distinct I will not at present venture 

 to suggest.
