that I made sure it was a distinct species. Mr. Winn has taken both 

 forms flying together at St. Hilaire, Quebec, and it was in his materia! 

 that I first claimed to be able to recognize two species. The majority of 

 the specimens which I saw subsequently in other Eastern collections 

 were of the more even form, and the more I compared, the less able did I 

 seem to draw any line between them. Still, 1 think the existence of two 

 species quite possible. It would be best determined by breeding. If 

 such is the case, which is Morrison's species will ha.ve to be determined 

 by comparison with the type in the Tepper collection at i\Iaddison, 

 Wisconsin. 



275. E. tristicula Morr. — This species is correctly identified. The 

 type is a male in the Brooklyn Museum. It bears no locality label, but 

 I believe it was described from Maine. Hampson's figure is from a 

 coloured drawing of it. Nesilejis Smith (No. 267) is evidently a variation 

 of it without the black collar, basal streak, and in the cell. A good picked 

 series of about fifty from Alberta, Manitoba, and a few from Windermere, 

 B. C, show every intergrade between the two. I have examined a very 

 much greater number. In some specimens, the black is replaced by pale 

 ochreous shading. In either form, the costa, median vein, and discoidal 

 spots may be rather distinctly paler than the ground, or quite concolorous. 

 But Jiesilens must sink as an exact synonym of re^nota Smith, female, 

 described from the Sierra Nevada. Prof. Smith agrees with me in this 

 reference. There are two female types in the Henry Edwards collection 

 in the New York Museum, from a figure of one of which Sir George 

 Hampson's has been copied. The shades in the figure are rather too 

 contrasting. The specimens are exactly like some from Calgary. A male 

 type Q){ remota is in the Washington collection, and differs from any that 

 I had previously noticed in having the space beyond the terminal line the 

 darkest part of the wing, and lacking all trace of dark shade or dashes 

 before it. I had previously seen a figure of this specimen in the British 

 Museum collection, and expressed a very strong opinion as to its distinct- 

 ness from the published figure. Examination of the actual specimen 

 showed it to be also a trifle violaceous, and proportionately shorter winged 

 than iiesiUns as I knew it, but on the whole much more like a small 

 specimen of that than I had expected. I subsequently found a Calgary 

 male nesiUns in Dr. Barnes' collection with the dark termen, and, accept- 

 ing Prof Smith's view of the matter, have changed my opinion as to its 

 probable distinctness.
