THE CANADIAN ENTOMOLOGIST. 33^ 



Alberta to be its most probable origin. I had for some years 

 previously had a couple of specimens in my collection from Regina, 

 Assa. In the spring of 1911 "cutworm" larva? were reported as 

 doing very serious damage to fodder and field crops in Southern 

 Alberta, round Lethbridge, Monarch, etc. (42nd Rept. Ent. Soc. 

 Ont. for 1911, p. 94 [p. 6 of the "Record"]— 1912). Larvie sent 

 to the Experimental Farm at Ottawa produced specimens of delorata 

 on Aug. 14th and 20th of the same year, the specimens being sent 

 to me for determination. I received a couple more niales from 

 Mr. Baird labelled High River, Sept. 1st, 1911, and have seen two 

 pairs taken by Mr. J. B. Wallis at Lethbridge on Aug. 23rd to 26th, 

 1912. Orthogonia was described from Glencoe, Nebraska. I have- 

 specimens from Colorado, and a very large number from Utah. 

 The few Canadian specimens I have seen have all been more uni- 

 formly dark olivaceous in tone than is usual with southern 

 examples, and have wholly dark secondaries. Morrison's type^ 

 which I have not seen, had the "markings well expressed," and 

 secondaries whitish inwardly. Pale secondaries are usual in my 

 southern series, but some have them very nearly as dark as Canadi- 

 an specimens, and differ scarcely if at all as to primaries. In short, 

 comparing Alberta specimens with some of my darkest from Color- 

 rado and Utah, there is really no difference worthy of remark. I 

 should never have considered the darkest forms to be worthy of a 

 varietal name, but as one has been named, let delorata stand for a: 

 dark olivaceous variation of orthogonia without pale shades ancT 

 with wholly dark secondaries in the male. I have previously 

 explained that the orthogonia recorded by me with a query as Mo. 

 236 in my original notes (Can. Ent., XXXVII, p. 53, Feb. 1905) was 

 a different species. I now believe that specimen to have been a 

 badly worn and bleached ridifigsiana. 



628. Euxoa rabiata Smith.— (Trans. Am. Ent. Soc, XXXVU 

 p. 255, Nov., 1910). Described from six males and two females from- 

 Volga, South Dakota; Colorado; and Calgar\% one of the females: 

 being from the latter place, and dated Aug. 29th. I happen to 

 have taken some notes on a group of specimens standing separated 

 in Smith's collection, from which, or from a selection of which the 

 description referred to was subsequently made. Judging from 

 these notes in conjunction with the description, I think it very
