HYPOTHETICAL LIST. 



■ The following list of species which have not been, as yet, positively 

 reported from the State, is composed of those forms which have been 

 iaken in neighboring States, or whose known range -seems to include 

 Indiana. Some of them, it will be noticed, are of very rare or acci- 

 dental occurrence in the locality where they have been found, and pos- 

 sibly may not be found at all within our limits. For the sake of 

 abbreviation references are made as follows:
