■102 THE REPORT OF THE No. 19 



by lepidopterists. There has been so much confusion in the genus, and it 

 was previously very difficult, in many instances, to get exact determinations. 

 Dr. Smith has gone into the subject very fully. Of the 25 species treated of, 

 nine are recorded from Canada. In addition four other species occur in 

 Canada, as mentioned in the Ottawa Naturalist, October, 1908. The old 

 name Homoptera is replaced by Phoeocyma of Hubner, an earlier name. 



Van Duzee, E. P, Studies in North American Membracidse. Bulletin 

 of the Buffalo Society of Natural Sciences, Vol. IX., pp. 29-129; issued April 

 18, 1908. This publication will prove of much value to hemipterists. Most 

 of the Membracidae, or "tree-hoppers," are of uncommon occurrence, and for 

 that reason, probably, the family has not been very much studied. The 

 author gives tables of the sub-families, genera and species, and, at the end, 

 a list of all species known to occur north of the southern boundary of the 

 United States.
