" If there is any need of an apology for the study of a local 

 fauna, it would seem to be sufficient to call to mind the numerous 

 problems of geographical distribution, life zones and dispersal that are 

 presented by every group of animals and for the solution of which 

 complete records of local faunae become indispensable. At first sight 

 it may seem less essential to secure such records from the different 

 parts of a large area having primarily one fauna) zone ; but the facts 

 reveal that in many cases the distribution of particular species presents 

 peculiar limitations, and the recognition of these is essential in any 

 consideration of more general groups. While the study of remote and 

 exceptional localities may give more striking and immediate results an 

 extended and systematic study of particular groups must be the basis 

 for final conclusions regarding many of the more obscure laws." 



On the same subject, Mr. Edward P. Van Duzee says:* "The 

 publication of faunal lists constitutes a very important element in the 

 literature of entomology as well as in that of other branches of Natural 

 History. They form the basis of our studies on the geographical 

 distribution of species and throw much light on the origin of our 

 fauna and its relation to that of other countries and zoogeographical 

 regions. ' ' 



Of recent years, quite a number of local lists of Heteroptera 

 have been published, among them, in addition to the two quoted 

 from, the following by Prof Osborn, " Contributions to the Hemipter- 

 ous Fauna of Iowa, " Proc. la. Acad. Sci., Vol. IV., and "Additions 

 to the List of Hemiptera of Iowa, with Descriptions of New Species," 

 Proc. la. Acad. Sci., Vol. V. Mr. Van Duzee has also published 

 " Hemiptera of Beulah, N. M.," in Trans. Am. Ent. Soc, XXIX, 

 March, 1903. There are in addition to these, " Preliminary List of 

 the Hemiptera of Colorado," by Prof. Gillette and C. F. Baker, 

 Bull. 31, Tech. Ser. I, State Agr. Coll. Exp. Sta., Ft. Collins, Col., 

 1895, and a number of partial lists by Prof. Uhler, which it is need- 

 less to recite. The list of Hemiptera contained in Prof Smith's 

 New Jersey List, so well known and appreciated by local entomolo- 

 gists, and last, but certainly not least. Prof Uhler's "Check List," 

 may also be cited. 



I am indebted to Mr. Otto Heidemann for determinations in 

 Coreidae and Aradidae, and to Mr. E. P. Van Duzee for the Penta- 



*"A List of the Hemiptera of Buffalo and Vicinity," Bull. Buff. Soc. Nat. 

 Sci., Vol. V, No. 4, pp. 168-204.
