48 THE CANADIAN ENTOMOLOGIST. 



The apical triangle, above the ocellic spot is the whitest part of the 

 wing, irrorated with fuscous below and interrupted on costa by three well- 

 defined, large costal spots, the outer the largest ; a line of pure white sur- 

 rounds these spots on all sides except the costal. The ocellic spot 

 occupies the lower half of wing, bounded outwardly by a narrow, irregular, 

 silvery-metallic line, beyond which are two to four small black dots, the 

 spot is white and is crossed horizontally by a row of dark dots above, a 

 faint line and a dark shade below ; the silvery-metallic outer line, in some 

 specimens continues around below the spot and up on its inner edge, 

 almost completely encircling it. Before the cilia is a pure white line, 

 from just below apex to dorsal margin and before this is a slightly wider 

 fascia of the dark colour, which continues into the apex. Cilia white, 

 lightly dusted with the dark colour. 



Hind wing : Smoky, fuscous, rather shining ; cilia pale fuscous, with 

 three very narrow basal lines, middle fuscous, outer and inner, whitish. 



Under side : Front wing, dark, smoky fuscous, paler along dorsum 

 and costal spots darker, faintly outlined with paler scales, a white dash 

 between outer spot and apex. Cilia same as above and preceded by a 

 pure white line. Hind wing, grayish fuscous, becoming darker at apex 

 and with one apical and two small costal dark spots. Cilia same as above. 

 Abdomen, above and sides grayish, below each segment black anteriorly, 

 cinereous centrally and gray posteriorly, giving it a very striped appear- 

 ance. Legs : Femora, whitish gray, tibiae and tarsi cinereous. 



Described from four $'5. Expanse : 20 to 24.5 mm. 



Two from Regina, VH., 18 and 20, and two Aweme, Man., VI., 29, 

 and IX., 31 (Norman Griddle). Qo-types, U. S. Nat. Mus. No. 8206, Mr. 

 Willing's and my collections. 



Since writing the above I have received from Mr. Ernest Oslar, 

 several additional specimens, collected in Platte Canon, Colo., VIII., 16, 

 and three specimens from unidentified material in U. S. Nat. Mus., 

 collected by Dr. W. Barnes, Glenwood Springs, Colo., Aug. and Oct. 

 The latter arc of bright ochreishbrown shades, Oslar specimens olivaceous- 

 gray. The maculation of all are the same; the species has therefore a 

 variation in colour, from ashy-gray, through the olivaceous-grays to a clear 

 ochreish-brown. (To be continued.)
