 the disk near the tip ; inferior wings with a narrow band 

 across the middle not attaining the inner margin and near 

 the tip larger spots, white.

A fine insect, which appears to inhabit almost every 

 part of the United States, though I have not met with 

 many specimens any where. Mr. Nuttall brought me an 

 individual from Arkansa ; Dr. Bigsby took a specimen as 

 far north as the Lake of the Woods, and I have found one 

 in Pennsylvania, another in Missouri, and a third on Red 

 river of Lake Winnepeek.
