138 AMERICAN COLEOPTERA. 



APPENDIX. 



Here I have given in full the original descriptions of thirteen 

 species, usually included in our lists, which are unknown to me, and 

 which, so far as I can learn, are unrecognized in this country. The 

 types are probably in European collections, but where I have been 

 unable as yet to ascertain. I should be obliged for any information 

 on this subject. 



It is probable that at any rate some of these species are known 

 under other names, and when they become recognized it is quite likely 

 that some changes in our nomenclature vvill result. As several are 

 described from uniques, it is by no means improbable that at least 

 some of them may represent extreme variations of previously de- 

 scribed species. 



It has been judged best to reprint the descriptions without any 

 attempt at translation, in order to avoid the chance of error. Many 

 of the works in which they were published are now so rare as to be 

 practically inaccessible to the majority of the students of our fauna. 

 No remarks or suggestions as to the probable position of the species 

 have been appended, those of each author being arranged in alpha- 

 betical order.
