396 THE CANADIAN ENTOMOLOGIST. 



the Kootenai List seem to me unquestionably tessel/ata, as that species is 

 known in the east. 



Acidifrons is not certainly distinct from nordica. It was described 

 from a male from California, now in the Washington collection, and a 

 female from Oregon, now at Rutgei's College. The former is more like 

 the ordinary form of nordica than the latter, from which Hampson's figure 

 oi acutifrons was probably taken. His figure of nordica is poor, that of 

 islandica resembling some Calgary specimens very much more closely. 

 The latter specimen is stated in the key to be of an Iceland specimen^ 

 but, comparing it with the British Museum series under that name, I found 

 it to be much more like some labelled ''ab rossica'' from Uliassutai 

 Mis., Mongolia. 



272. E. divergens Walk. — The types of divergens Sindversipeliis are 

 in the British Museum, and are alike. I'he former is a male from Nova 

 Scotia; the latter labelled merely "U.S.A.," appears to be a male with 

 female abdomen attached. The ordinary Calgary form is similar. 

 Hampson's figure is of type divergens. Factor is Smith, was described in 

 1900 from five females from Glenwood Springs, Colo. The type is in the 

 Washington collection. Abar Strecker, was described the previous year 

 from a single female from the same locality. I have seen the type of this 

 in the Field Museum at Chicago, and consider the two names to refer to 

 the same form, the latter of course having preference. It is by no means 

 unlikely that the species is a somewhat obscure form oi divergens. I have 

 nothing compared with Smith's or Strecker's types, but at any rate 

 divergens and abar must be closely associated. Fusiviaciila Smithy 

 described in 1891 from a single male from California, in which the 

 reniform merges with the orbicular on the median vein, seems to differ 

 from abar in that character only, which is very likely merely varietal. 

 I have specimens which I call divergens from Calgary, Kaslo, Glenwood 

 Springs, and Yellowstone Park, in which the reniform runs back, and, as is 

 often the case with such abberations, not always evenly on both wings. 



273. E. redimacula Morr. — The form cccurring here is that figured 

 by Sir George Hampson from Colorado. Much the same form occurs in 

 the East, and I have a male from New York differing chiefly only in 

 being browner and less grey. But a form occurring much more commonly 

 in the East is more even in colour, has slightly larger and rounder dis- 

 coidal spots,, more even s. t. line without the inward streaks, and paler, 

 dark margined secondaries. So unfamiliar did the form seem to my eye,
