30 THE CANADIAN ENTOMOLOGIST. 



Stout, dark brown, almost black. Front covered with an even mixture of 

 dark brown and paler scales, the latter showing more abundantly over 

 vertex, on collar and patagiae. Antennœ sordid white, ringed with dark 

 brown, simple in both sexes. Above, the ground colour of all wings is a 

 soiled brownish white, overlaid with dark rich brown, mingled with black 

 scales. Thorax above black centrally, has a conspicuous line of pure 

 scales crossing it between wing bases, with front and scutellar region dark 

 brown. Abdomen paler brown, broadly ringed with darker on second 

 segment, without dorsal tufts. The dark brown basal and extradiscal lines 

 cross the primaries, but many hair lines along inner margin in basal and 

 central spaces quickly fade out. The basal composed of three parallel 

 hair lines, the two outer being heavier and black, includes a space, paler 

 than the ground colour, traversed centrally by a fine hair line of brown. 

 It starts from costa one-third out, makes a long sharp angle almost to 

 discal spot, thence backward nearly straight, to inner margin, one-fourth 

 from base. In the male co-type this line is suffused with black scales. 

 The extradiscal two-thirds out runs straight across costa, makes a sharp 

 outward angle below it, and thence nearly parallel to outer margin, 

 slightly waved as it reaches the inner, a little more than two-thirds out. 

 A narrow indistinct geminate pale line borders this outwardly. A ])ale 

 area occupies the central portion of the wing, with an extension across 

 extradiscal below costa toward apex, and an isolated spot between veins 3 

 and 4 on subterminal space. The large oblique linear discal spots are 

 rich brown, conspicuous, and are surrounded by a ruddy brown suffusion, 

 which appears again on the apical prolongation, and more faintly on the 

 spot on subterminal space, particulaily in the female type. Subterminal 

 space darker, especially opposite cell, where a cluster of black scales 

 starts within extiadiscal, extends across it to margin, and upward toward 

 apex. It is traversed centrally by an indistinct volute white Ime. 

 Terminal line not well marked. Fringes paler than ground colour. 

 Secondaries darkened with brown scales along outer and inner margins, 

 are almost devoid of them centrally and along costa. The geminate pale 

 line and the basal lines are outlined at inner margin, the former traceable 

 nearly to costa Discol dots round, dark brown. Terminal line black, 

 broken at veins. Fringes pale, cut with black opposite veins. Beneath, 

 all wings pale brownish ashen, darkened apically, the lines as above faintly 

 showing on primaries, and on secondaries, doited on veins. Discal dots 

 on primaries are large, oblique, linear, black, on secondaries round, black.
