ORTHOrTERA OF INDIANA. 127 



AcKNOwi.EDG^rENTS. — During my study of the Orthoptera and in 

 the preparation of the present paper I have heen greatly aided by 

 that nestor of orthopterohigieal students, Mr. S. H. Seudder, of Cam- 

 bridge, Massachusetts. To hhn, more than to all others combined, 

 is due our present knowledge of the classification and distribution 

 of North American Orthoptera. Always willing to answer questions 

 and ever interested in any new form which was discovered, his coun- 

 sel has been to me both inspiring and helpful. His many works 

 upon the subject have been freely used in preparing the present 

 paper. Profs. Lawrence Bruner, of Lincoln, Nebraska, and A. i 

 Morse, of Wclleslcy, Massachusetts, who, next to Mr. Seudder, are 

 the leading authorities on ilie grou}), have also rendered me much 

 aid in comparing and verifying specimens sent to them for examina- 

 tion. Only a ])erson situated as I have been, far from any great ref- 

 erence collection, can duly appreciate such kindness as they have 

 shown. To Dr. J. L. Hancock, of Chicago, and Mr. A. N. Caudell, 

 of Washington, D. (*., I am also indebted for favors shown; the 

 former having parsed in review tlie collection of Tettiginge made in 

 the State. Otliei- ackudwledgments are made in the body of the 

 paper. 



Illustrations. — The illustrations used have, for the most part, 

 been taken from the late Prof. Otto Lugger's '"Third x\nnual Report 

 of the Entomologist of the State Experiment Station of the Univer- 

 sity of Minnesota;"' permission to use them having been kindly 

 granted by the present State Entomologist, Prof. F. L. Washburn. 

 A number of original drawings have, however, been made expressly 

 for the paper, by S. Fred Prince, of Lincoln, Nebraska, and Miss 

 Lillian Howcnstein, of the V. S. Department of Agriculture. The 

 Secretary of the Smithsonian Listitution has also kindly granted the 

 use of the figures illustrating tlie abdominal appendages of the 

 Melanopli, which are from ]\Ii'. Scudder's "Revision of the Orthop- 

 teron Group, ]\k'lano])li," published in Vol. XX, of the Proceedings 

 of the U. S. National Museum.
