THE CANADIAN ENTOMOLOGIST. 405 



Front dusky, cinereous. Thorax brown, \viih a dark transverse band 

 anteriorly. Abdomen as thorax, 2nd segment a little darker, posterior 

 edge of each segment whitish. 



Fore wings obtuse at apex, outer margin well rounded, same colour 



as thorax, the costa rather darker and the cross lines distinctly lighter 



than the ground colour ; basal line double, very irregular, being angled 



sharply outwardly at cell and below vein 2 ; median line also double, not 



well marked, making a sharp outward angle to include the conspicuous 



black discal dot, then running in an almost straight line to middle of inner 



margin ; extra-discal line also double, dislocated at vein 6, then in a 



regular curve parallel to outer margin ; both median and extra-discal lines 



show in more or less well defined whitish spots on veins 2 to 6 inclusive ; 



and there are short black dashes on each of these veins between the 

 median and extra-discal lines ; submarginal line white, conspicuous, 

 Regularly scalloped at each vein, and forming a distinct V at anal angle ; a 

 fine black marginal line ; fringe dotted with dark brown between veins. 



Hind wings well rounded, lighter brown than fore wings, with six 

 darker lines ; the first two are basal, and do not extend further from inner 

 margin than to vein 2 ; the next two lines are extra-discal and almost 

 complete ; the two outer lines extend completely across the wing ; a very 

 small and faint discal dot ; marginal line and fringe as on fore wings. 



Beneath paler ; fore wings with a linear discal dot, and the extra- 

 discal markings of the upper surface reproduced ; basal portion of wings 

 without markings except a dark spot on the costa, indicating the position 

 of basal line. 



Hind wings as above, but with all the lines more regular, and reaching 

 to the costa ; the discal spot is distinct, black ; first extra-discal line is 

 diffuse and very evident ; the three outer lines appear as spots between 

 the veins, the outermost line being least conspicuous. The. under side of 

 thorax and of the basal segments of the abdomen is very pale, almost 

 white, but the posterior portion of the abdomen is nearly black.
