species have become adapted to bog- or swamp-plants where they 

 are subject to very humid conditions or at times must be able to 

 undergo temporary immersion. 



Acknowledgements: The authors wish to express here, briefly, 

 their sincere appreciation to those who have kindly assisted in 

 these studies. We are indebted to Dean F. F. Moon, Ncav York 

 State College of Forestry, for the opportunity of carrying on these 

 investigations. The drawings haA'e been made by Mr. J. R. Sim 

 of Ashtabula, Ohio. Mr. A. E. Fivaz has taken many of the photo- 

 graphs and assisted in the field work. Director W. E. Sanderson 

 of the State Forest Camp has very kindly permitted us to use 

 boats, canoes, tents and other equipment of the Summer Camp. 

 The plants have been determined by Dr. W. L. Bray, Syracuse 

 University, and Dr. H. P. Brown, New York State College of 

 Forestry. The map of Cranberry Lake region has been drawn 

 from a map of the Adirondacks by the Conservation Commission 

 of New York State by Mr. Paul W. Stickel under the direction 

 of Professor H. C. Belyea. Dr. M. W. Barrows of Ohio State 

 University identified the spiders. For the determinations of in- 

 sects thanks are due as follows : Dr. H. H. Knight of the Uni- 

 versity of Minnesota, the Miridae; Dr. H. B. Hungerford of the 

 University of Kansas, the Corixidae; Dr. H. M. Parshley of Smith 

 College, the Aradidae; Mr. H. G. Barber of Roselle Park, N. J., 

 the Lygaeidae; and Mr. J. R. de la Torre Bueno of White Plains, 

 N. Y., many of the Saldidae. 



HOMOPTERA IN THE VICINITY OF CRANBERRY LAKE 



By Herbert Osborn 



Family CICADIDAE 



This family is not represented in the Cranberry Lake region 

 by any number of species, the only one which has been definitely 

 recognized being Tihicen canicularis. The group is interesting 

 on account of the extended life history of the 17 year Cicada 

 and the root-feeding habits of the immature forms. They are of 

 economic importance because of the punctures caused by the 

 females in depositing eggs which are laid in the twigs or smaller 

 branches of various forest trees. It would seem almost certain 

 that Tihicen rimosa should be found in this region but no specimens 

 have been observed. Also the species described as T. novehora- 

 censis by Fitch would seem likely to occur as it was discovered 

 from the eastern part of the state. 



Tibicen canicularis (Harris). 



This, as stated above, is the only species definitely recognized. 

 It was singing during August of the present j^ear, but no speci- 

 mens were captured.
