except for the golden markings, with purple reflections. 

 The body is dark purple, with three yellow abdominal 

 bands in the female and four in the male. The brown, 

 spherical eggs are placed singly on currant stems, and the 

 larva works up or down the pith. The larvae hibernate 

 when nearly full-grown; pupate the following spring in a 

 silk-lined cavity just under the bark; and emerge during 

 June and July. There is one generation a year. 



Synanthedon is the genus Sesia of authors, 

 Synanthedon the name ^^ properly belonging to a 

 pictipes 



genus of Sphingidas. The work of this 



species is often confused with that of exitiosa, but pictipes 

 prefers old trees with rough bark and works more often 

 on the trunk and larger branches than at the base of the 

 trees. Its cocoon is similar to that of exitiosa but smaller. 

 The adults, both sexes of which resemble the male exitiosa, 

 are also smaller. They fly during June and July. It is 

 said that this species attacks June-berry and chestnut 

 in addition to those three "favored" by exitiosa, but it 

 rarely does much damage to any.

 farmer, he often does not know what is the matter. The 

 group does not seem to be a "popular " one. The following 

 are samples of some of the subfamilies.
