A LIST OF THE HEMIPTERA 



Of JBlzj^clZo and 'Vtctruity . 

 By Edward P. Van Duzee. 



The publication of faunal lists constitutes a very important 

 element in the literature of entomology as in that of other branches 

 of Natural History. They form the basis of our studies on the geo- 

 graphical distribution of the species and throw much light on the 

 origin of our fauna and its relation to that of other countries and 

 zoo-graphical regions. 



But few local lists of the Hemiptera have as yet been published 

 in this country hence the distribution of many of our species is still 

 largely a matter of conjecture . Of the more important contributions 

 of this character may be mentioned Dr. Harris' Catalogue of the 

 insects of Massachusetts and Dr. Fitches' List of the Homopterous 

 insects of the State of New York, published in 1S51. Mr. Uhler's 

 List of the Hemiptera from West of the Mississippi River can hardly 

 be classed as a local list but it is extremely valuable for the copious 

 notes on the distribution of many of the species then mentioned. 

 From 1885 to 1891 M. L'Abbe Provancher published Vol. Ill of his 

 Faune Entomologique du Canada ; but, although a work of consider- 

 able magnitude, it has little value, owing to the many erroneous 

 determinations it contains and its author's limited knowledge of this 

 o-roup of insects. Within the last few years several local lists of more 

 or less value have appeared, devoted, in part at least, to the Hemip-
