 the under side of the body, and the breathing-holes show 

 plainly on the sides of the rings. The moth comes out 

 during May in Massachusetts. When the time comes 

 for it to leave the cocoon, by means of an acid liquid it

 the hairs and scales from the under side of the wings, the 

 little hook or bristle on the hind wing and the ring 

 through which it passes on the fore wing can be seen.
