The caterpillar of this moth has been reared by Messrs. Koebele, 

 Caulfield, French, and by Thaxter, in Massachusetts, from various spe- 

 cies of oak. The moth is said by Grote to be an exceedingly common 

 and very variable species. It is found from Canada, Maryland, and 

 Virginia southward to the West Indies. Mr. Caulfield states that the 

 caterpillar was fully grown by June 15 at Montreal ; it spun up in a 

 leaf June 18 and the moth emerged the latter end of July. Prof. G. 

 H. French gives a detailed account of its early stages in the Canadian 

 Entomologist for January, 1884.
