a narrow line, about one-fourth the width of the silver stripe. At the 

 lower angle of stripe there is a very slight tooth. Beyond the stripe 

 in middle of wing is a short silvery white streak, outwardly touching 

 the angle of the subterminal line and inwardly slightly underlapping 

 the end of the silvery stripe. On costa before subterminal line is a 

 long, narrow, triangular, outwardly oblique white mark, and beyond 

 the line a much smaller white costal dash. The subterminal line 

 starts from outer fifth on costa, angles obliquely outward to upper 

 third, then parallels termen to dorsum; it is shining grayish white, 

 outlined inwardly by a clear brown line; above the angle is a light 

 ochreous brown triangular spot in apical space; below the angle the 

 subterminal is bounded outwardly by a line or shade of mottled white 

 and grayish brown. The terminal line is black, above the angle solid, 

 below the angle divided into four or five black dots, the latter are 

 ground color in the interspaces; in the upper third this black line is 

 bordered on both sides by a vertical white line, on the outer side 

 overrunning the cilia. On the outer third of wing the veins are over- 

 laid with shining gray, more or less outlined with scattered black 

 scales. The dorsal edge is narrowly silvery white from base to 

 tornus; the outer half is edged above with scattered black scales. 

 Cilia irridescent pearly white. 



Hind wing light gray, cilia paler; underside the same shade below 

 middle, above and under side fore wing darker gray. 



Described from ten specimens, Mer Bleue, Ontario, July 2-10, col- 

 lected by C. H. Young, whose name it is a great pleasure to honor. 



" Mer Bleue " is a huge sphagnum swamp about 20 miles south of 

 Ottawa. This species is nearer to bidens Zeller than any other North 

 American form known to me ; it is slightly smaller, but of the same 

 dainty appearance; it can be readily separated by the white streak 

 between stripe and termen. In this respect it is nearer pascuellus 

 Linnaeus.

CRAMBUS BIDENS Zeller. 



Mr. Young was successful in collecting a large series of this rare 

 species near Ottawa about the middle of July, including many 

 females, which possess a peculiarity that I have not seen recorded. 

 In this sex the broad white stripe is suffused on the upper half with 

 brown ; this suffusion does not extend to the upper edge, which is nar- 

 rowly silvery. I have also captured this species in a piece of bog- 

 land in the pine barren district of New Jersey, near Lacy, about the 

 middle of the State, about 10 miles from the ocean. Curiously the 

 same species of orchid were growing in this spot as I observed a year 

 before in the sphagnum swamp at Mer Bleue. None of the Lacy 

 specimens showed this suffusion.
