are wanting on the three segments beliind the head, which 

 bear a double row of reddish tubercles above. The horn is 

 yellow and granulated. 



It feeds, according to Abbot, " on the fringe-tree {C/iionnjt' 

 thus virgifiica), called old-man's-beard from its clusters of white 

 blossoms, and also on the privet and lilac. I procured several 

 in Virginia," he continues, '' upon the last-mentioned shrub ; 

 they went into the ground July 31st, but every one of them 

 died in the chrysalis during the winter. After I had been 

 several years in Georgia, I found some on the old-man's-beard 

 in June, which buried themselves on the 22 nd of that month 

 and came forth on the wing July 20th. It is not a common 

 moth. Of those insects which go into the earth, and breed 

 twice in the year, it is best to procure the spring caterpillars, 

 which are much more likely to survive, the autumnal ones 

 commonly dying in chrysalis in the winter." This remark 

 also applies to the rearing of various European species.
