ACKNOWLEDGMENTS OP AID RECEIVED. 



1820 to 1834, the most noted of American Entomologists, and for 

 much of that time resided at New Harmony, Posey County, Indi- 

 ana, where much of his writing was done and where, doubtless, most 

 of his species mentioned as "from Indiana" were taken. 



From the accompanying map of the State it will be seen that 

 the collection has been made from so many different localities as to 

 make it a fairly representative one. Wherever a species has been 

 taken in more than five widely separated counties they are not 

 mentioned in detail, but the phrases "throughout the State," 

 "throughout the northern half of the State," etc., are used. 



ACKNOWLEDGMENTS. To one situated, as I have been, far from 

 any great reference collection, such a paper would not have been 

 possible had it not been for the aid, usually freely given,* which I 

 have received from noted students and specialists in Coleoptera, 

 throughout the country. To many of these, specimens have been 

 sent for examination, verification or naming. Those to whom espe- 

 cial acknowledgments are due are: Chas. Dury, of Cincinnati, one 

 of the most enthusiastic and successful of naturalists, who has col- 

 lected beetles for 40 years, and yet seems good for 40 more. He 

 has helped me out with many a species and his collection has added 

 a number to my list from the State. Chas. Liebeck, of Philadelphia, 

 compared and verified many specimens with those in the Horn 

 collection in that city. Frederick Blauchard, of Tyngsboro, Massa- 

 chusetts, one of the most careful and experienced of American Cole- 

 opterists, passed the Ilaliplidte in review and compared many other 

 species with the Leconte types at Harvard. H. C. Fall and Dr. A. 

 Fenyes, both of Pasadena, California, are specialists, respectively, 

 of Ptinidffi and Aleocharina 3 , and both have given me much aid in 

 those groups. Mr. Fall has also helped me with some of the Silph- 

 ida? and Staphylinidte. Chas. W. Leng of New r York City has 

 passed in review the species of Cychrus and Donacia, an*.] also veri- 

 fied numerous other species which have been sent him froxi time to 

 time. John B. Smith of New Brunswick, New Jersey, veiified all 



*An exception must be made of a well known Coleopterist whose collection doubtless 

 contains many specimens from Indiana. When I asked the privilege of looking through it 

 for the purpose of making notes on these, he wrote: "I cun not admit anyone to my collec- 

 tions for the purpose mentioned, for my specimens are delicately mounted and in places over- 

 'crowded, ami the resulting damage would be great." When also asked to verify some speci- 

 mens of Pluilacridce, he wrote: "I am too busy to undertake the identification of small 

 species -in groups which I have monographed. I have made my descriptions clear and it 

 seems to me that you can make the identifications with the expenditure of your own time. 

 It is surely n<~t a. source of much satisfaction to me to find that a monograph, upon which I 

 have put uuu-h ti'ne and labor, will not serve the purpose for which it was intended, i. e., to 

 permit others to idenlify their material."
