LIST OF COLEOPTERA TAKEN AT SPARROW LAKE, ONT. 



BY JOHN HAMILTON, M. D., ALLEGHENY-, PA. 



Sparrow Lake is an expansion of the Severn river, situate a little south 

 of lat. 45 and east of 8o° longitude. Geologically, this part of Ontario 

 belongs to the Laurentian formation, and that of a very rugged type. 

 The southwest side of the lake, where these coleoptera were taken, save 

 in a few spots among the rocks, is wholly uncultivated and uncultivable to 

 the Georgian Bay, a distance of from 20 to 30 miles. Till recently it ' 

 sustained an immense forest growth, mostly pine, which has now disap- 

 peared, and has been succeeded by a dense and almost impenetrable 

 jungle of briars and bushes of many deciduous species. 



So far as coleoptera are concerned, a large majority of the species 

 inhabiting this district must be considered autocthonous, and it is not 

 difficult to determine approximatively such as are following the little 

 spots of cultivation that are being interjected. The collecting was done 

 from July 20th to August 15th. That the list is no longer is not alto- 

 gether the fault of the collector ; in fact, in addition to the paucity of 

 species, while some are in great abundance, the majority are each repre- 

 sented by from one to three examples only. 



As this part of Ontario is in a comparatively primitive condition, and 

 no record of the coleoptera inhabiting it has been observed, the sub- 

 joined list may be of some interest: —
