THE PINE-LEAF AND THE GREEN-WINGED 

 CHERMES 



A bulletin on Maine Chermes now in process of preparation 

 is of technical character and will not be sent to the general mail- 

 ing list of the Station. The two species discussed in this bulle- 

 tin, however, are of economic interest in the State and for this 

 reason the following popular account of them is prepared for 

 immediate distribution in ' Maine. The bulletin on Maine 

 Chermes will not be ready for distribution until next year.
