divergefis, and has the pale median vein ; but the ordinary spots are not 

 outlined in pale and are different in shape, opening on the pallid costa. 

 This is also a much grayer species and the contrasts are more sharply 

 marked. It has a little the api)earance of /urtivns, but the powdery 

 markings and complete median lines easily distinguish it." The median 

 vein is never as conspicuously pale as in most of my divergens, and it has 

 not nearly so much resemblance to either this ox furtivus, as the above 

 remarks might lead one to suppose. Compare my notes under pestula 

 (supra). This i» the commonest form of the group and is extremely vari- 

 able in every particular. The most off-type specimen I have seen is 

 briefly referred to under servitus {q. v.), July and August. Prof Smith 

 tells me that the type is from Cartwright, Man. I have a specimen from 

 there which I believe to be nordica, but as the locality is not mentioned 

 under the description, I think he must be mistaken, andHhat the type is a 

 Calgary specimen. It is in the U. S. National Collection. I should never 

 have recognized the species from Sir George Hampson's figure. 



272. E. divergens, Walk. — Usually very common at treacle, and a 

 pest at light. June and July. A !}? in perfect condition on Sept. 8th, 

 1893, may possibly have been one of a second brood. 



273. E. redimicula, Morr. — Common. July to middle Sept. 



274. E. servitus, Smith. — The ? type(imdated) is from Calgary, and was 

 taken m 1895. ^^ '^ figured in Ent. News, VI., PI. xv. (December, 1895). 

 I have never come across another specimen. Tiie $ type, figured in Sir 

 George Hampson's Catalogue, is from Colorado, and is in the U. S. 

 National Museum at Washington, where the 9 probably is also. I agree 

 with Prof. Smith in thinking that this is realty an aberration oi redimicula. 

 It looks like that species with the costal gray "smudged" from the base to 

 the posterior end of liie cell, obliterating the discoidal spots and the black 

 in the cell except for a small black spot about its centre. I have a speci- 

 men of what I feel quite sure is uordica $ "smudged" in a similar manner, 

 but without the black spot. This has been labelled servitus by Prof. 

 Smith, which it most obviously is not. In addition to the smudge, this 

 uordica gives the impression of all the colours having run together. 



275. E. tristicula, Morr. — Common some seasons. June to middle 

 Aug. Until quite recently Prof Smith considered this to be si/ens, Grt., 

 under which name it has tor long been known in N. American collections. 

 Shortly prior to the publication of his recent list he told me that the names 

 referred to the same species, but he now finds that such is probably not
