20 Forty-first Report on the State Museum. 



and Shade Trees, in 1881, has extended the number to 106, occurring 

 on the different species of piues in the United States, while omitting 

 several Hemiptera (bugs) which occur in greater numbers upon other 

 kinds of vegetation. It will be safe to say that we know of, at least, 

 125 species of pine-inhabiting insects. 



About thirty species are recorded as infesting spruces {Abies nigra 

 and A. alba), and about the same number the firs {Abies balsamea, 

 mainl}^). Dr. Packard {loc. eit.) names fifteen species on the Junij)ers 

 {Juni2)erus Virginian us and J. communis), and but three on arbor vitse 

 {Thuja occidentalis). 



The species known to feed upon the Hemlock are the following:
