The present publication forms the second part of Volume II., "Contri- 

 butions to Canadian Palsecntology." It consists of a report by Dr. S. H. 

 Scudder of Cambridge, Mass., upon the Coleoptera of the interglacial 

 beds of the vicinity of Toronto, to which is added an appendix by Dr. 

 A. P. Hopkins of Morgantown, W. Va., on Scolytid borings from the 

 same deposits. 



The Survey is greatly indebted to both of these gentlemen for their 

 gratuitous work upon this contribution to the literature of fossil ento- 

 mology.
