Euxoa {Rhizagrotis) perolivalin Sm. Lethbridge, Alta., (Strickland). This 

 species was referred to Rhizagrotis by Smith, by reason of the male an- 

 tennae being ciliate merely. The character does not appear to be quite con- 

 stant, and one of the Lethbridge males has the antenn* more obviously 

 serrate than any I had before seen, (Dod). 



Euxoa pestula Sm. Lethbridge, Alta., (Strickland). This species is very 

 close indeed to pleuritica Grt., and may be a dark form of it, (Dod). 



Euxoa thanatologia var. sordida Sm. Lethbridge, Alta., (Strickland). 

 Breeding results, in conjunction with a study of Kaslo, B.C., material and 

 previous examination of type, has convinced me that boretha Sm. and 

 sordida Sm. are both forms of one extraordinarily variable species pre- 

 viously described as Porosagrotis thanatologia by Dyar, but best referred 

 to Chorizagrotis Smith, which Hampson treats as merely a section of 

 Euxoa, (Dod). 



1589. Euxoa sponsa Sm. Kaslo, B.C., (Cockle). 



1590. Euxoa cJioris var. cogitans Sm. Lethbridge, Alta., (Strickland). 



1593. Eu^oa hollemam Grt. Maple Bay, Vancouver Island, B.C., Aug. 24, 

 (Day). 



1672. Euxoa pallipennis Sm. (Syn. alcosta Sm.), Lethbridge, Alta., Aug. 21, 

 1914, (Strickland). A new Canadian record, (Dod). 



1689. Euxoa hoJoherha Sm. Kaslo, B.C., (Cockle). 



1801. Mamesira trifolii Eott. Lethbridge, Alta., Aug. 20, 1914, (Strickland). 

 A new Alberta record, all previous records being my mutata, which Hamp- 

 son claims is a Cardepia, very close to nova Sm., (Dod). 



1849. Mamestra segregata Sm. Bow Eiver, at the mouth of Fish Creek, Alta., 

 A])ril 17-24, (Tams). Pine Creek, near Millarville, Alta., April 1, 

 (Dod), and May 8 (Tams). iSe^re^ra^a was described from Laggan. Gv^- 

 sata Sm. described from here, appears to be a synonym of this, and negussa 

 Sm., also described from here a variety without the blackish markings. 

 The species is very variable, the forms easily intergrading, and an examin- 

 ation of male genitalia gives no evidence suggesting two species, (Dod). 



2021. Graphiphora uniformis Sm. Lethbridge, Alta., (Strickland). The first 

 Alberta record. This species has usually stood as furfurata or peredia 

 in Manitoba collections. The two latter names refer to one species, very 

 closely allied to uniformis (Dod). 



2031. Graphiphora presses Grt. Kaslo, B.C., (Cockle). Not in Dyar's Kootenai 

 list. 



2048. Streichia muricina Grt. Midnapore, Alta., April 12, 16, 28, May 12, (Dod 

 and Tams). I have previously recorded the form occurring here as 

 pJusia'formis, but whilst I have not so far recognized a distinct species 

 under that name, I consider it probable that all Alberta and British 

 Columbia specimens which I have seen are muricina, (Dod). 



2067. Cleoceris popuU Strk. Lethbridge, Alta., (Strickland). 



Xylina rivida Dyar. Kaslo, B.C., (Cockle). N"ot in the Kootenai list. 



2079. Xylina petulca Grt. Kaslo, B.C., (Cockle). Not in the Kootenai list. 



2093. Xylina ferrealis Grt. Kaslo, B.C., (Cockle). Not in the Kootenai list. 



2095. Xylina innominata Sm. Eed Deer, Alta., Aug. 30, and Sept. 4, (White- 

 house and Tams). New to Alberta (Dod). 



2113. Xylina capax G. and R. Blackfalds, Alta., Aug. 17-24, (Whitehouse). 

 New to Alberta, (Dod).
