THE PENTATOMIDAE OF NEBRASKA 



BY JOHN TODD ZIMMER 



This paper is to be considered merely as a faunal list repre- 

 senting the family Pentatomidae in Nebraska as it is known at 

 the present time. The list is based for the most part on specimens 

 actually present in the collection of the University of Nebraska 

 although several species are included, parenthetically, on the 

 authority of previously published records when no specimens are 

 now at hand. Necessarily the list is not a final one as, until re- 

 cently, little collecting of Hemiptera has been done in the state 

 and further work along this line will, undoubtedly, bring to light 

 many species which are, as yet, unrecorded from Nebraska. In 

 fact, the number of species is being constantly increased, and it 

 has been found necessary to revise this paper, after it was once 

 completed, in order to include a half dozen or more forms found 

 since the list was begun. 



Some synonymy has been included, but it has been restricted 

 to a single citation (the first) of the various specific names ap- 

 plied to each species. Generic changes have not been mentioned. 

 The synoptic keys are based mainly on the work of such men as 

 Uhler, Stal, Signoret, Summers, Heidemann, Montandon, Van- 

 Duzee and Schouteden whose various tables have been rear- 

 ranged and modified so as to include only Nebraskan forms. 

 Some of the characters used are new ones, especially in cases 

 where I have found what seem to be more constant differences 

 than those employed in published synopses. 



To Professors Lawrence Bruner and Myron H. Swenk, of the 

 University of Nebraska, and to Mr. E. P. VanDuzee of Buffalo, 

 N. Y., many thanks are due for valuable suggestions used in the 

 preparation of this paper, and acknowledgments must also be 

 made to the various authors whose synopses have been utilized 

 in the keys.
