many errors occurred in the determination of these insects prior to 

 the publication of Capt. Casey's monograph of the Scydmaenidae, and 

 so many new species have been added to our fauna, that it has been 

 thought advisable to republish the whole list of our species. To Rev. 

 P. Jerome Schmitt of St. Vincent's College, who has spent years of 

 study on the ScydniKnidae and Pselaphidae, and through whose syste- 

 matic collecting many new species of these remarkable coleoptera have 

 been discov'ered, I am indebted for the list and the notes on the same, 

 which are here given, and for the preparation of which credit is due 

 him. The species listed are all, with few exceptions, in the collection 

 at St. Vincent's College, and all occur in southwestern Pennsylvania.
