marked by a wavy reddish line, and near the tips of 

 the fore wings tliere is an eye-like spot. The caterpil- 

 lar feeds upon the sassafras-tree. Before making its 

 cocoon, it fastens to the twig, with silken threads, the 

 leaf that is to cover its cocoon, so that it shall not fall 

 in autumn ; then it spins its cocoon on the leaf, bend- 

 ing over the edges to cover it. 



The Luna, or " Pale Empress of the Night," is of a 

 delicate light green color, and the hind wings are pro- 

 longed into a tail, and each wing has an eye-spot, which 

 is transparent in the centre and surrounded by rings 

 of white, red, yellow, and black. The caterpillar lives 

 on the walnut and hickory, and is bluish green, with 

 a yellow stripe on each side, and yellow stripes across 

 the body. It draws together two or three leaves and 

 spins its cocoon inside of them. The cocoon falls with 

 the leaves in autumn, and the next June the beautiful 

 Luna appears. 



The Polyphemus Moth is reddish yellow, with a trans- 

 parent eye-spot, divided by a slender line and encir- 

 cled by yellow and black, on each wing, and on the 

 hind wings adjoining the eye-spot is a large blue spot 

 shading into black.
