Synoptic tables orNonio C^oiiora of C'OI.EOPTEKA with 

 uote«« and Syiioiiyiiiy. 



BY GEOROE II. HORN, M. D. 



The tables whicli follow arc presented with the hope that they may 

 prove useful to the students of the Anierieau fauna. During; the life- 

 time of jNIr. G. R. Crotch, the idea was su<;gested of prepariiisr similar 

 tables for as many of the genera as had not been so dealt with, should 

 the species be amenable to such treatment. The death of Mr. Crotch 

 seriously interrupted the work, and while many genera have been al- 

 ready published by myself, none of his have as yet appeared. The 

 manuscript having been collected will be published as rapidly as my 

 leisure will allow of its review. I have taken the liberty of making 

 such additions to the manuscripts as seemed necessary to make them 

 plainer or more useful.
