which is of a beautiful shade of green, is ornamented on the 
sides by raised lines of silvery white, and is altogether a beauti¬ 
ful object, so far as coloration is concerned. The cocoon is in 
form like that of Actias Inna, but is much more dense, and, after 
it has been spun up, is injected by the larva with a fluid, which 
appears to precipitate a white chalky matter through the fibers 
after it has dried. Efforts to reel the silk have hitherto amounted 
to but little. The insect is double-brooded in the southern States. 
In Pennsylvania and north¬ 
ward it is single-brooded. 
The moth ranges across 
the entire continent and 
into Mexico in the South.

leaves, and falls in the autumn to the ground. A number of 
aberrant forms and local races have been described, and there is 
considerable variety in the depth of the ground-color of the wings
