208 JOHN B. SMITH. 



Head, palpi and thorax umber brown, ([\<c irrorate with white, patagfise also 

 white tip})ed and witli a deeper brown line margining the discal space at sides; 

 the line variably distinct, but traceable in all specimens seen by me. Abdomen 

 umber brown with indistinct lateral deeper brown lines. Primaries umber 

 brown, with whitish scales scattered over the surface; a pair of deep brown 

 transverse lines angulated over the cell, and another pair of more distinct^ 

 strongly dentate darker outer lines. The first line starts from basal fifth of costa, 

 the second from basal fourth. These two lines extend obliquely out, the .>iecoud 

 one to the dark discal dot, then turning they run to the hinder margin near the 

 base, where they are lost in an indistinct reddish brown spot. The third line 

 starts from costa a little beyond the middle, curves outward around the cell, and 

 ends near the middle of the hinder margin. This line is sharply toothed on each 

 vein. The outer line, which is darkest and is followed on its outer side by a 

 narrow, brown shade, starts from the outer fourth of costa and crosses the wing 

 parallel to the last, and equally dentate on the veins. The space between these 

 two lines is more heavily overlaid with white scales than any other part of the 

 wing. Two black dashes rest on the wing, one between veins 2 and 3, and the 

 other between veins 3 and 4, and extend from the median vein to the outer line. 

 A row of terminal black venular spots. Sometimes the space beyond the outer 

 dentate line, nearly to the margin, is umber brown, a p^ler transverse line run- 

 ning along the outer dents of the dark line. Fringes brown, cut with white- 

 Secondaries umber brown, lighter at the base, and sometimes with a faint trace 

 of a median band. The fringes are marked alternately with white and brown. 

 The under side of all the wings is grayish brown, with a darker colored line, 

 scarcely visible, crossing the outer part. Fringes as on the upiier side. Expands 

 2— 2.50 inches; 50— 63 mm. 



Hab. — Canada to Florida ; westwai-d to the Mississippi. 



The species is toleral)ly widely distributed, but htirdly common 

 anywhere. It varies much in the depth of ground color, and in the 

 distinctness of maculation ; all the lines, however, being at all times 

 traceable. The larva has been best described by Lintner.

" Cinereous. Fore wings with a zigzag oblique black line, and 

 with several lanceolate black marks. Hind wings brownish, [laler 

 toward the base ; cilite white. Length of the body 10 lines (i inch.) ; 

 of the wings 24 lines (2 inches).

This is Walker's description, and wdiat it referred to has been a 

 puzzle to American entomologists. It has been referred by Mr. 

 Grote as identical with harrisii; Mr. Strecker, on p. 117 of his work,
