120 THE CANADIAN ENTOMOLOGIST. 



sprinkled with brown atoms ; a band of these crosses front beneath 

 antennae, and across thorax in front. Each segment of abdomen narrowly 

 edged with pale buff posteriorly, with a dorsal black spot anterior to it, 

 largest on terminal segment. Second segment slightly darker. All wings 

 broad, rounded, edges waved. Colour pale bluish-ashen, nearly white on 

 discal space and beyond extra-discal line. Cross lines narrow jet black, 

 heaviest on fore wings at costa. Basal line on fore wings one-fourth 

 out, curves sharply outward below costa, then recedes toward base, 

 as it crosses wing. Intradiscal when present encloses but does not 

 obscure the large, elongate-oval discal ringlet, below which it can be traced 

 faintly to inner margin, parallel with basal line. Extra-discal about two- 

 thirds out, runs outward from costa, making a sharp angle at vein 5, 

 reaching in one broad outward scallop the inner margin at about its 

 middle. A pale olive-brown broad shade line runs outside the extra-discal 

 and within the basal lines, sometimes clouding the entire basal area. A 

 well defined serrate white line divides subterminal space centrally, outside 

 which the wing is slightly darker. Two of its teeth at costa and opposite 

 angle of extra-discal are filled in with jet-black scales. Fine marginal line 

 black, with dots inside it, between veins. Fringes dusky. Hind wings 

 with basal line heavy, black, running straight across wing, sometimes double 

 part of length. Extra-discal angulate opposite cell, recedes toward base, 

 passing beneath and touching the elongate oval discal ringlet, thence 

 wavy to inner margin, parallel with the basal line. Otherwise as in fore 

 wing, the three costal serrations of white line bordered internally with 

 black. Beneath evenly dark gray, heaviest on fore wings. These have a 

 broad black or dusky shade line, from costa just before apex, running 

 parallel to margin, but narrowing and fading out before reaching internal 

 angle. Basal and extra-discal lines faintly shadowed. Discals on all 

 wings large, linear jet black. Abdomen beneath and legs white, the latter 

 powdered with brown scales. 



Type, o* taken in Catskill Mts., July 24, 1908; type, 9 from same 

 locality, August 4, 1908, and co-types in author's collection. Readily 

 separated from its congeners by the large linear discal spots beneath, and 

 from larvaria by the course of basal and extra-discal lines on hind wings 

 at inner margin. In that species they both curve strongly downward. I 

 suspect this may be Walker's larvaria (List Lep. Br. Mus., xxi, 344, 

 i860), since he mentions the large discal spots beneath, but his name falls, 

 having been preoccupied by Guenee. It may, however, explain the 

 association of these two species under that name.
