CHERMES OF MAINE SPRUCES. 
BY EDITH M. PATCH, ORONO, MAINE. 
Six species of gall forming Chermes have been under observation on spruces in 
the vicinity of Orono during the season of 1909. 
1. Chermes pinifoliae Fitch. This dark species develops in a cone-like gall 
on the black and red spruce (in which connection it was named abieticolens in 1879 
by ‘Thomas and subsequently merged by error with abietis in 1897) and migrates to the 
needles of the white pine to oviposit (in which connection it had been previously 
named pinifoliae by Fitch in 1858, and merged by error with pinicorticis in 1869). 
A historical discussion with full reasons for resurrecting this doubly merged species 
under the original name of pinifoliae, which has been discarded for about 40 years, 
will be published presently together with a technical description of the species, by - 
the Maine Agricultural Experiment Station.
