wings dark brown ; towards the posterior margin 

 obscure ochreous, with obsolete, abbreviated, 

 blackish, transverse lines ; posterior margin with 

 a slender black line and dirty white edging ; 

 beneath marbled with black and white, the 

 black prevailing across the middle and base of 

 the wing. 



OBSERVATIONS. 



Many of the insects belonging to this genus 

 are decorated with beautiful colours, and with 

 eye-like spots upon the wings ; but the present 

 species is of a more simple and unassuming 

 character. Without any imposing attractions 

 to arrest the eye, it exhibits an agreeable neat- 

 ness in the disposition of the contrasting colours, 

 on the inferior surface of the wings. But its 

 chief title to our attention is the great altitude 

 of its native climate. It inhabits the bald 

 summits of the White Mountains of New- 

 Hampshire, and appears to be limited to that 

 inhospitable region. Mr. T. Nuttall sent me a 

 specimen some time since, taken by himself,* 

 and Mr. Charles Pickering of Salem, has re- 

 cently presented me with an individual in an 



PliATE 50.
