 and August. 



39. E. o/iva/is, Grt. — Common some years. July to middle Sept.

My specimens entirely lack the pale contrasts shown in Holland's figure, 

 and the costa is scarcely paler than the rest of the wing. 



240. E. maiines, Smith. — (Can. Ent., XXXV., 5, 131, May, 1903.) 

 Described partly from Calgary material. The type is a Calgary specimen, 

 and is at Rutgers College. It stood for years in my collection, and was 

 sent out as Eidingsiana, of which it appears to be the northern represen- 

 tative. In the description, comparing it with that species, Prof. Smith 

 says, " it is smaller, darker, less powdery in the V ? , with rays on the 



veins even less marked In the $ $ the distinction is well 



marked, that of maimes differing little from the ,$ , while in Eidingsiana 

 all the examples of that sex are paler, more ashen, dusty gray, with less 

 contrasting maculation." Common some seasons. End July to middle 

 August. 



241. E. pugionis, Smith. — Described partly from Calgary material. 

 The type is from Colorado and is in the U. S. National collection. Form- 

 erly confused with flavidens. Comparing them. Prof. Smith says in the 

 description, " In the new form the general colour is lighter, the contrasts 

 are much greater, and the secondaries are pure white." In several of my 

 specimens, however, the secondaries are distinctly smoky on the outer 

 third, or even outer half Rare. August and Sept. At light and flowers. 



242. E. cogitans, Sm. — A fine ^ at light. August 13th, 1903. 

 Prof Smith says, "A little smaller and not quite so well marked as my 

 Colorado specimens, but the same, I think." Sir George Hampson treats 

 cogiians c^s Vi synonym oi c/ioris, Harv., and 1 cannot be sure that his 

 figure of that species is not the same as my specimen. 



243. E. f<er/usca,Gv\. — A $. July 26th, 1900. Smaller than Prof. 

 Smith's examples from ^\'ashington, otherwise similar. 



244. E. punctigera,\NA\V..^K^\.ht\- rare, and all my specimens but 

 one are $ ? , that one having been taken /;/ cop. It is redder than any 

 of my 9 ^ , and as a $ that I have from Regina, Assiniboia, is of much 

 the same shade, the colour difference appears to be sexual. I had the 

 name titubatis given me for this species, and have sent specimens out as 

 such. Titubatis I have never taken here. July and August,
