10 HETEROPTERA OF EASTERN NORTH AMERICA. 



each to its author or the one who first used it. The drawings 

 for those marked "original" were made by Miss Mary C. Foley, 

 artist for the Bureau of Entomology at Washington, D. C. 

 Through the kindness of Dr. W. E. Britton, State Entomolo- 

 gist of Connecticut, I was able to borrow a number of the cuts 

 prepared for the "Hemiptera of Connecticut," recently pub- 

 lished by the Connecticut Geological and Natural History Sur- 

 vey. Under each of these credit is given its author and that 

 work. 



Dr. Wm. A. Riley and Prof. A. G. Ruggles, of the University 

 of Minnesota, kindly loaned me such of the cuts as I desired 

 which were used by Otto Lugger, former State Entomologist 

 of Minnesota, and they are credited to Lugger or their orig- 

 inal author. From Dr. M. W. Blackman, Chief of the Depart- 

 ment of Forest Entomology at the New York State College of 

 Forestry, Syracuse, N. Y., I was able to secure a number of 

 the cuts of Heteroptera used in Technical Bulletin No. 16, pub- 

 lished by that Department, and credit under each of these is 

 given that work. Mr. Harry B. Weiss, of the State Depart- 

 ment of Agriculture, Trenton, N. J., kindly furnished a 

 number of the cuts of Tingids used by Barber and Weiss 

 in their "Lace Bugs of New Jersey." Dr. S. A. Forbes and 

 Mr. T. H. Frison, of Urbana, 111., furnished numerous cuts 

 used in the publications of the Illinois State Natural History 

 Survey, and Dr. W. J. Holland some from the Annals of the 

 Carnegie Museum. In addition to the above a number of illus- 

 trations in previously published papers on Heteroptera have 

 been reproduced and due credit is given the author under 

 each. 



Acknowledgments. — When I first began to form my pri- 

 vate collection of Heteroptera on which this work is mainly 

 based, Prof. P. R. Uhler, of Baltimore, Md., was the leading 

 authority in this country on the group. He bore, in fact, to 

 our knowledge of American Heteroptera the same relation 

 that Leconte and Horn did to that of Coleoptera and S. H. 

 Scudder to Orthoptera. In other words he was the pioneer 

 who laid the foundation of our present knowledge of American 

 Heteroptera. To Uhler I sent many of the first species I col- 

 lected for naming and from him I received without delay the 

 lists of names with comments on those species which were to 

 him of especial interest. A few of his determinations have 

 since proved to be wrong, and to a number he gave "Uhler,
