It appears that the genera composing this family 

 belong almost entirely to Northern climates, they 

 seem peculiar (as far as is known at present) to 

 Northern Europe and to North America. In 

 warmer regions I am inclined to think that Catas- 

 copus takes the place of Elaphrus. It is certain 

 that some of the species belonging to the former 

 genus abound in marshy places and on banks of 

 rivers ; should it eventually appear that a large pro- 

 portion of the species of Catascopus frequent such 

 localities, there cannot be a doubt of the connection 

 of the above genera. The Baron De Jean has 

 arranged Catascopus between Thyreopterus and 

 Graphiptera, with the latter it can have little rela- 

 tion, and certainly it does appear singular for a
