ELAPHIDION PARALLELUM, Newm., AND PHYMATODES 



VARIABILIS, Fab. 



BY C. H. T. TOWNSEND, CONSTANTINE, MICH. 



In the Oct. number of this journal I noticed with interest the article 

 by Mr. Clarkson on Elaphidion villosum, Fabr. I have reason to believe 

 that the same is partly the case also with E. parallehim, Newm., which I 

 find to be the common oak-pruner here. But I do not agree that it is 

 always, or even in the majority of instances, the case with either species.
