Head, crests of the thorax and abdomen gray ; these crests are edged 

 with white and in the anterior ones the margin is formed by a black and 

 white line ; abdomen cinereous ; antennae above testaceous, underneath 

 white banded with brown ; the primary wings are shaded and clouded 

 with black, brown and white, and towards the apex have three indistinct 

 bands, the first white internally abbreviated, the second dark-brown, and 

 the marginal one gray including a transverse series of black crescents ; in 

 the disk of the wing is a pallid silvery signature, representing the Greek 

 letter gamma, or the Roman Y,'the forked part pointing to the costal 

 margin ; from the upper point of the fork a white curving line runs 

 obliquely to the anal margin of the wing near its base ; secondary wings 

 light brown, or drab, with the nervures, and posterior margin broadly, dark- 

 brown ; fringe alternately dark and light ; underneath the wings are cin- 

 ereous, darker at the apex,

Body gray. Antennas and thorax, when laid bare, testaceous ; primary 

 wings gray with a faint reddish tint, a broad brown spot, or cloud, almost 

 triangular, traverses the middle of the wing, which partly includes, and is 

 partly edged, by a sickle-shaped silvery streak ; the part representing the 

 handle of the sickle being broader than the rest, and sending forth 

 externally near its apex a short branch, which, with the internal apex of 

 the handle, forms a fork ; the inner tine, or branch, of which terminates 

 in a slendtr line running in a curve to the costal margin, where it touches 

 the scutellum ; a brown indistinct cloud, or band, also runs obliquely from 

 the anal to the apical angle of the wing ; a very minute, pale streak marks 

 it just transversely above the former angle ; the posterior margin is slightly 

 indented ; the secondary wings are reddish-brown, with an obsolete, pale, 

 submarginal band.

 Nova Scotia by Dr. Mac Culloch and in Canada by Dr. Bigsby, 



[309.] Body, legs and antennae fawn-colored, as are likewise the paler 

 parts of the wings ; primaries clouded and streaked with dark, and reddish- 

 brown ; the disk of these wings is occupied by a large cloud of this color 

 inscribed with two, sometimes silvery, and sometimes golden, brilliant 

 metallic spots, tending to form an obtuse angle with each other ; the upper 

 one, or that nearest the base of the wing being acuminated towards that
