336 THE CANADIAN ENTOMOLOGIST. 



237. Euxoa riimatana Smith, = Agrotis dargo, Strecker, the latter 

 specific name having preference by five years. I have three male co-types 

 of rumaiajia from Volga, S. D , one of which I have labelled as being 

 exactly like a type of dargo, from Loveland, Colo., in the Strecker 

 collection, which is a trifle paler only. I have also compared the male 

 and female types oi runiatana at Rutger's- College. I have Calgary and 

 High River specimens of the same species. A male from Chicago is very 

 similar, but darker in colour, with smal'er orbicular, and less of dark 

 border to secondaries. 



238. This species is not plagigera, at least so far as I can at present 

 discover, but has been described from Calgary as Rhizagrotis perolivalis 

 by Smith (Journ. N. Y. Ent. Soc, XIII, 194). A male and female co-type 

 are in my collection. Its nearest named ally appears to be olivalis Grt., 

 from which it differs considerably in maculation, and structurally in having 

 male antennae ciliale instead of serrate-fasciculate. 



239. E. olivaiis GxX. — One of my Calgary specimens I have com- 

 pared with the type, a female in the British Museum from Colorado. The 

 olivalis of the Washington collection when I was there was ridingsiana. 

 Agema Strecker, from Colorado, is in all probability a dark olivaceous 

 specimen of olivalis, though I refrain from making the reference definitely 

 at present. I am under the impression that nearly all the specimens I 

 have seen in collections standing as plagigera have been olivalis I do 

 not know where Morrison's type is, nor whence it was described. 

 Oblojigistigma Smith, described from four females from Black Hills, 

 Montana, is a browner, smoother form, but very much like olivalis, and 

 not certainly distinct. Hampson figures Smith's species correctly from 

 Colorado, though another Colorado specimen which I found associated 

 with it in the collection was distinct. I have a long series from Stockton, 

 Utah, which appear to grade through. I have seen four specimens 

 labelled " types " of oblongistigina. Two females are in the Brooklyn 

 Museum, and a male in the Henry Edwards collection in the American 

 Museum of Natural History. Prof. Smith claims that the latter, though of 

 the same species, cannot be of the type lot on account of its sex. A 

 female at Washington from Nevada Co., Calif., bears the museum red 

 *' type " label, but. Prof. Smith tells me, erroneously so. That is fortunate, 

 as it is a distinct species from those at Brooklyn, and nearer quadridentata 

 G. & R. It may be what Prof. Smith has since described as fliitea (Trans. 

 Am. Ent. Soc, XXXVI, 255, Nov., 19 10).
