PSYCHE.

by a tliirti of an inch wide; tlie heavier 

 veins of the oak are avoided. They are ex- 

 ceedingly slow ill movement. One re- 

 mained almost motionless for four or five 

 hours and then climbed the side of the box 

 slowly and cautiously. 



The earliest pairing of the sexes was noted 

 Sept. 2J. and a male was in one instance al- 

 most continuously coupled with a female for 

 eight days, and died immediately afterward, 

 while the female lived until December lo, 

 laying eggs at intervals. Mr. L. Trouvelot 

 who also reared this insect found that the 

 male usually died within two days after the 

 close of copulation. One female laid 3S 

 eggs between Sept. 10 and Oct. 5 and died 

 Oct. II with 15 developed and 5 or 6 unde- 

 veloped eggs in her ovaries. The eggs are 

 dropped loosely upon the ground and it has 

 repeatedly happened to Mr. Trouvelot and 

 myself that eggs which did not hatch after 

 the winter had passed went over a second 

 winter and then gave out the young. Out 

 of no eggs laid one October only 7 hatched 

 the next year, in July; in another year the 

 earliest eggs hatched June 22. 



Mr. J. Elliot Cabot informed me that at 

 Beverly, Mass., the country people call these 

 insects "witches horses."
