WICKHAM A LIST OF COLEOPTERA. I 25 



A LIST OF COLEOPTERA FROM THE SOUTHERN 

 SHORE OF LAKE SUPERIOR. 



With Remarks on Geographical Distribution. 



BY H. F. WICKHAM, M. S. 



Since the publication in 1S50 of Dr. Leconte's "General Remarks 

 on the Coleoptera" in Agassiz's "Lake Superior," a good deal of 

 attention has been bestowed upon the beetles of that region, partially 

 because of the considerable number of new species brought to light by 

 the explorations preceding the bringing out of the report, and perhaps 

 more by the early-recognized fact that a number of the forms taken in 

 the district have a wide Northern and Alpine distribution. In 187S 

 Messrs. Hubbard and Schwarz brought out their "List of Coleoptera 

 Found in the Lake Superior Region," which contains the results of 

 long-continued and careful collecting by the authors, with the addition 

 of all the species taken by Dr. Leconte in his previous explorations. 

 Over twelve hundred names are given of Coleoptera from various 

 points on both shores of the lake and from some of the larger islands. 

 Several short reports were afterwards published by Dr. Leconte, which 

 contain lists of species taken by members of the Geological Survey of 

 Canada, but only a few are additional to those enumerated in the 

 Hubbard and Schwarz List. 



My own collections were all made at Bayfield, Wisconsin, oii the 

 southern shore of the lake, and about sixty miles from the western 

 end. Most of the work leading to the preparation of the lists men- 

 tioned in the preceding paragraph had been done far to the eastward, 

 and to this fact may be due the large number of names — over 200 — 

 contained in my list and w^anting in the others. About 500 of those 

 I enumerate had already been found at some point in this basin. 



Bayfield lies in a lumbering district and is surrounded by heavy 

 forests of coniferous trees with their usual concomitants of underbrush, 

 the whole making a closely-packed mass of vegetation almost impene- 

 trable and so dense as to preclude the use of the beating or sweep-net
