DESCRIPTION. 



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 : antenna? 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 cinereous, darker at the apex.
