COLEOPTERA. 



Nearly all of the 114 species in the following Catalogue -were obligingly 

 determined for me by Dr. J. L. Leconte of Philadelphia. Besides those 

 enumerated, many others were collected, but were unfortunately lost 

 by the accidental fracture of the bottle which contained them. 



I have added a list of 34 species, not observed in this district by 

 myself, but brought by Mr. Robert Bell from the Augmentation of 

 Grenville, and the neighbourhood of L'Orignal, on the south bank of 

 the Ottawa. 



Cicindela longilabris^ Say. — Hamilton's Farm on the River Rouge, 2nd
