PSrCHE.

I obtained the egs^s a number of times 

 during the month of September. They were 

 from confined females, deposited on the 

 sides of the breeding cage, appai'entlj being 

 glued to the wood. They are black, 2.5 to 

 3 mm. long, subcjlindrical in shape, with 

 numerous longitudinal ridges having jagged 

 edges. At the lower end is a distinct flange, 

 inside of which is a circular depression, 

 from which arises a conical projection as 

 shown at a in the accompanying illustration. 



These eggs are probably glued to the bark 

 of trees, especially evergreens, as surmised 

 by Mr. Uhler, and apparently this is the 

 state in which the species passes the winter. 



I am indebted to my assistant, Miss Freda 



Detmers, for the drawings from which the 



accompanying figures have been reproduced.
