mathematically exact they are at least approximately correct, 

 and, it is hoped, will save those interested much weary labor 

 in searching for data. Some of the lists were not easily com- 

 pared, one or two being encumbered with much synonymy 

 that had to be unraveled before any definite results could be 

 arrived at. The following have been used, as the best expo- 

 nents of the faunae to which they relate. 



The Coleoptera of Michigan. H. G. Hubbard and E. A. 

 Schwarz. Here are listed 1231 species and varieties from 

 Lake Superior, and 1786 from the lower peninsula of Mich- 

 igan. 



List of Ottawa Coleoptera. W. H. Harrington. 



List of Coleoptera by Dr. A. S. Packard in his work on 

 "The Labrador Coast." 



Vega-Coleoptera und Hemiptera. I have used the list 

 given by Dr. Bergroth in Entomolog. Nachrichten, 1885. 

 This relates to the insects brought back by the Vega from 

 Behring Strait and the Chuck-chee peninsula. 



Catalogue of the Coleoptera of ]Mt. Washington, N. H. 

 E. P. Austin. 



Notes on Coleoptera found at Fort Simpson, Mackenzie 

 River. Dr. J. L. Leconte. I ov\e to the kindness of Dr. 

 John Hamilton, a manuscript copy of this list. 



The Coleoptera of the x\lpine Rocky Mountains, Parts I 

 and II. Dr. J. L. Leconte. 



With this mention, the follov/ing table explains itself: The 

 first column of figures shows the number of species, of that 

 part of the Alaskan Coast treated of in the foregoing pages, 

 which are found also in the localities set opposite: the second 

 and third columns dealing in the same way with those of the 

 Stikine Canon and Glenora. The fourth, fifth and sixth col- 

 umns show what percentage of the fauna of their respective 

 headings is derived from, or common to, localities of which 

 lists are compared.
