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.
