CRESSONIA JUGLANDIS 203 



in proportion. A week later the white granules of 

 the body were set each in a purple-brown circle, the 

 circles being wider around the granules forming the 

 obliques. 



The caterpillars fed for twenty-one days after the 

 last molt, then lay on the bottom of the tin for nine 

 days, when pupation took place. They were about 

 three inches long. Out of doors they go into the 

 ground. 



The pupa was an inch and a quarter long, rather 

 slender, and of a black-brown. The head had four 

 rough points, two on the apex, two just below in 

 front. The eye-covers were studded with rough 

 points, smaller than those on the head. The antennae- 

 covers were roughly serrated. The tongue-case was 

 concealed. The last few abdominal segments had pro- 

 jecting rough points, which are of use in preventing 

 the pupa from slipping back when working its way to 

 the surface of the earth for the moth to emerge. The 

 last segment is flattened and compressed, instead of 

 tapering gradually, as most pupae do. 



The moths are not specially attractive. The color 

 is fawn or aslies-of-roses, sometimes having a pink- 

 ish tinge. The wings are crossed by lines of darker 

 brown. The males are usually darker and smaller 

 than the females, and their fore wings are less notched. 

 Their antennae are widely pectinate, almost feathery. 



The eggs were laid in July, the pupae were formed in 

 September, and the moths emerged late in the follow- 

 ing June.
