The following resolution was moved by Dr. J. Chester 
Bradley: 
That the Committee on Nomenclature be requested to formulate 
rules for the preservation and fixation of family names, with a view 
after approval by the Society to ultimately presenting them to the 
Nomenclatorial Committee of the International Congress _ of 
Entomology. 
That the Committee on Nomenclature be requested to prepare a list 
of a few of the more important names in each order which are in danger 
of being lost or changed in sense by strict application of the rules of 
nomenclature, which it is desirable should be preserved, and present 
this list, after approval by the Society to the International Commission 
on Nomenclature with the request that the rules be suspended in the 
case of these names, and their use permanently authorized. 
On motion, the resolution was adopted and referred to the 
Committee on Nomenclature.
