Though this is an exceedingly variable species, yet all the specimens 

 agree in the grauite-gray, thickly-mottled wings, with the three subparallel 

 lines ending triangularly on the cost:i, and the large subdivided l)rown patch 

 in the middle near the outer edge of the fore wing; the broad ochreous or 

 smoky band common to both wings beneath is usually present. It varies 

 much in the distance between the lines. In one example from Pennsylvania, 

 the two inner lines are very contiguous, and both very sinuous; in an exam- 

 jile from London, Canada, received from Mr. Saunders, the ground-color is 

 whiter than usual, and the lines and spots very heavy, and the second line 

 runs on to the hind wings. It also varies in the cloudiness of the wings: 

 some are whitish, with fine speckles and no lines on hind w ings; others more 

 typical are granite-gray from being so coarsely and densely speckled, with a 

 prominent discal dot and a broad submarginal shade. When much rubbed, 

 the costo-apical and median spots remain to indicate the species. The Flor- 

 idaii form does not differ from the others, except that the lines are lather 

 heavier, and there are indications of two lines on the hind wings, on the upper 

 side, near the inner edge. One individual was collected in Colorado by Mr. 

 Mead. It is rather larger tlian specimens from Victoria, Vancouver Island, 

 collected by Mr. G. R. Crotch, and is much darker, hciug ihwch as in eastern 

 specimens. The lines on the fore wings are rather Inroad, and the dark 

 broken spot in the middle of the wing, near the outer edge, is obscure and 

 imited tt) form a liiint patch; th(> liind wings are without any submarginal 

 shade, as in .some eastern examples. 



I am disposed to regard my Jf. sex-macula fa, from Caribou Island, 

 Laljradcjr, Straits of Belle Isle, as a variety of this species. It is very closeh*
