insect fauna. Just at this time we especially desire notice of 
published records not given in this list, and data on 
correctly determined specimens in collections which have 
not been accessible to us. As the authors have undertaken 
a special study of the North American Jassidae, they would 
be pleased to examine specimens in that group from any por¬ 
tion of the country, and will give determinations for the pri¬ 
vilege of retaining desiderata.
