apex being very large, triangular in shape and oblique ; they are separated 

 by white costal spots, each containing a small black costal dot ; the outer 

 white spot sends a white line into ternien below apex, through black 

 terminal line into cilia, it encloses a blackish apical spot. The pearly- 

 white, shining ocellic bars are joined together below, and enclose a 

 narrow fawn space, dotted with black, above it is a larger black shade. 

 On the outer third of dorsum is a shining pearly-white dot ; between it and 

 the inner ocellic bar the ground colour is rather heavily powdered with 

 black. There is a broad central fascia of ground colour, edged inwardly 

 with white, and in middle near dorsum dotted with black, and a few 

 blackish scales scattered through the centre. Terminal line black ; cilia 

 leaden-metallic. 



Hind wing gray ; cilia paler gray, with a darker basal line. Under 

 side the same. Under side fore wing darker gray, costal spots faintly 

 repeated. Cilia leaden-metallic, with black basal and terminal lines. 



Fourteen specimens : Aweme, Manitoba, all collected June 27, 1905, 

 by Mr. Norman Criddle, in whose honour the species is named. 



Epitiotia Keimebecana, sp. nov. 



Expanse, 13 to 15 mm. 



Head light fuscous ; palpi cream white inside, light fuscous outside, 

 apical joint dark fuscous ; thorax dark fuscous, tips of patagia light gray ; 

 abdomen fuscous, anal tuft cinereous ; legs cream-white, shaded with 

 dark brown. 



Fore wing : Basal area blackish-brown, a dark gray shade extends 

 from basal area along costa to apex, and is continued as a narrow black 

 terminal line to tornus. Enclosed in these dark and gray shades, the 

 entire outer two-thirds of wing are white; the usual white dorsal spot and 

 an abnormally large white ocellic spot joining together, but their relative 

 positions indicated by a shade of scattered gray and black scales between 

 them. The basal area on dorsum extends to inner third, its outer edge is 

 slightly outwardly oblique to above middle of wing, then obliquely inward 

 to costa ; the lower two-thirds is finely dentate. The gray costal shade 

 is marked with four paler geminate spots on the outer half, and before the 

 apex the gray and white is shaded with a yellowish-coppery tinge. The 

 ocellic spot is defined on both sides by vertical shining white bars, each 

 outlined with black scales. Cilia black, divided by a gray line on lower 

 half 



Hind wing light smoky-gray, cilia paler, with a gray basal line. Under 

 side grayish-white, shaded with brown along costa. Under side fore wing 

 smoky-black, costal spots faintly repeated, grayish-white below Told.
