186 THE CANADIAN ENTOMOLOGIST. 



in the place that may be from tune to time selected for its sessions. In 

 this way we trust that much may be done for the furtherance of our 

 favourite brancli of science, and that Entomologists generally, from all 

 parts of the continent, will bring together their types of new species and 

 the surplus of their collections for mutual information and benefit. 



Without further trespassing upon your time and attention, I beg to 

 thank you, gentlemen, for the kind consideration you have shown to my^ 

 colleagues and myself during our term of office, and with hearty wishes 

 for the continued prosperity of our Society, 



I have the honour to be, gentlemen. 



Your obedient servant,

ON SOME CHANGES IN THE NOMENCLATURE OF NORTH 



AMERICAN COLEOPTERA, WHICH HAVE BEEN 



RECENTLY PROPOSED. 



BY JOHN L. LECONTE, M. D., PHILADELPHIA. 



Since the issue of the Check List of N. A. Coleoptera by the late 

 Mr. G. R. Crotch, I have been asked by several persons interested in that 

 branch of science, if I would advise them to change the labels in their 

 collections in accordance with the nomenclature of several familiar genera 

 as therein set forth. To all such applicants I have answered, that such 

 changes are not expedient, unless they are fully convinced of the propriety 

 of admitting them. For my part, I considered them quite unnecessary, 

 and still further, contrary to the code of laws of nomenclature under 

 which I supposed we were acting. 



Circumstances, which it is unimportant for me to specify, have 

 prevented me from heretofore making known the views upon which I 

 formed the opinion thus given, but as confusion of ideas upon the 

 adoption or non-adoption of Mr. Crotch's nomenclature now exists, I 

 think that the time has now arrived for a full discussion of the 

 subject.
