 the eoHection lias becMi made from so many different hx-alities as to

AcKNowLEDGiMENTS. — To One sitiuited, as I have been, far from 

 any trreat reference collection, snch a paper wonld not have been 

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

 have received from noted students and specialists in Coleoptera. 

 throno-hont the country. To many of these, specimens have been 

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

 cial acknowledg-ments are dne are : Chas. Diiry. of Cincinnati, one 

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

 lected ])eetles for 40 years, and yet seems g-ood f(n" 40 more. He 

 lias 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 Blanchard, of Tyngsboro. ^Nlassa- 

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

 opterists. passed the Ilaliplida' in review and compared many other 

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

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

 of Ptinida^ and Aleoeharina\ and both have given me much aid in 

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

 klva and Staphylinidw. Chas. W. Leng of New York City has 

 passed in review the species of CijcJinis and Do)iacia, and also veri- 

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

 time. John B. Smith of New Brunswick. New Jersev. verified all 



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

 contains many specimens from Indiana. Wiien I asked the privilege of looking througii it 

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

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

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

 mens of Phalacridte, he wrote: "1 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 not a source of much satisfaction to me to find that a monograph, upon which I 

 have put much time and labor, will not serve the purpose for which it was intended, i. e., to 

 permit others to identify their material."
