The Department of Geolog^y and Natural Resources was first 

 organized as a Department of Geology and Natural History, its 

 name being afterward changed for political reasons alone. It has 

 therefore been the custom of both the present director of the De- 

 partment and his predecessors to issue from time to time, in the 

 annual reports, papers on the Natural History of the State. 

 Among the many papers so published have ])een Jordan's "Fishes 

 of Indiana" in the Sixth Annual Report; Hays' "Reptiles and 

 Batrachians" and Blatchley's "Butterflies" in the Seventeenth 

 Report; Blatchley's "Orthoptera of Indiana" in the Twenty-sev- 

 enth Report; Cook's "(lall Insects" in the Twenty-ninth Report, 

 and Hahn's "Mammals of Indiana" in the Thirty-third Report. 



In accordance with previous custom the following paper on the 

 Coleoptera of Indiana was prepared and oifered for publication as 

 a part of the Thirty-fourth (1909) Report. The State Printing 

 Board refused to issue it as a part of said volume, and the paper 

 was therefore withdrawn and is issued as a special bulletin of the 

 Department of (ieology, the authority for so doing being embodied 

 in the following section of chapter 181 of the Acts for 1907 : 



Six-. 2. The rtireftor of said Department may, at his fliscretiou. have 

 printed from time to time snch matter in l)nlletin form as he may deem 

 espec-ially important, and the same shall be paid for out of any funds 

 appropriated for the expenses of the Dei)ai-tment. 



On account of the small sum ($8,800 per year) allotted for the 

 expenses of the Department of Geology, it has been possible to 

 issue but one thousand copies of the bidletin.
