1 Occurs abundantly on the trunks of pines during most of the month of September 

 at Bath ; abundant also at Schoharie. 



2 Very abundant at Center at this date, where at least a dozen could be seen from 

 one point, resting on the upper surface of leaves of shrubbery. The conspicuously 

 marked larvae had, during the summer, been very common on Vaccinia and other 

 plants. September 1st, its peculiar cocoon of strong and very open meshes, showing 

 plainly the pupa suspended within, was found spun between leaves of willow (Salix 

 humuli). The imago was last seen September 30th. It has not been observed at 

 Schoharie.
