Forewings light grey basally and terminally (sul)terminally evi- 

 dently meant. W. 1).), " the whole median space blackish discolorous 

 . A black basal dash .... Lines not strongly de- 

 fined .... Orbicular circular, dusky filled, reniform pale 

 and narrowly black-ringed .... claviform black outlined, 

 dark filled. Subterminal line pale .... with black dashes 

 preceding it, especially at interspaces 2-4 and 5-7 . . . Ter- 

 minal space blackish like the median space." I examined the 

 type in Febrifary, 1910, and (hough I was unable U) match it very 

 exactly, it very strongly suggested an intermediate form between 

 some very pale grey, and some very dark uniform l)rown specimens' 

 which I had taken at Calgary. Intermediate f(^rms between these 

 extremes luue since been bred. The condition had suggested 

 itself to me when I saw a figure of Dyar's type in the British Museum 

 in the previous year, and seemed quite obvious when I subsequently 

 saw a lot of material kindly loaned me by Mr. Cockle, including 

 another figure of the type. 



Var. boretha Smith. Described as a species (Condensed 

 description)": " Dull smoky brown. Collar inferiorly pale; 

 the pale portion limited above by a transverse black line. Costal 

 region more or less contrastingly paler, tending to yellowish, spots 

 discoloured, yellowish. Cell black filled ... A black mark 

 below median \ein in basal space. Subterminal line of the ground 

 colour, marked by the darker colour of the terminal space 

 preceded by a series of sagittate black marks in the interspaces. 

 Orbicular tending to ovate, yellowish, contrasting. Reniform in- 

 completely black margined, yellow, with smoky central line." 

 Described from 3 cf d^ and a i^ . Smith adds that the species 

 appears to be allied to terrealis. This is explained by the fact 

 that he had on several occasions named Calgary specimens of it 

 "terrealis'' for me, under which name a form of it appears in the 

 earlier portion of my Alberta List. Terrealis is known to me only 

 by the type, a cf from New Mexico in the Brooklyn Museum 

 (Neuma-gen collection). This has ciliate antennie, and is referable 

 to the Rhizagrotis (Rhiacia Hbn.) section of Euxoa. A figure of it 

 is pretty well reproduced by Hampson. It is probably allied to 

 flavicollis Sm., and I do not associate it with the species now under 

 discussion, nor did I recognize it in Smith's collection. He also
