ably E. a c e r i n u m " ; but see under no. 5. Also in the 

 Herbarium from Keene, Essex co. (Professor Peck). N.Y. 



The specimens from Garrison, from Long Island and part of 

 those from the Indian Ladder are lighter and more violaceous, the 

 others all a bright crimson. Perhaps there are really two forms ; 

 Carman's description fits the violaceous specimens.

 mite is Eriophyes acericola ( Carman) .
