III. "Revision of the Orthopteran Group Melanopli (Acri- 

 diid,e), with Special Reference to North American 

 Forms," by Samuel Hubbard Scudder. (Proc. U. S. Nat. Mus., 

 Vol. 20, pp. 1-421, Plates I-XXVI, 1897.) 



The greater portion of the material studied in the paper before us 

 was the property of Mr. Scudder; but a great number of specimens, 

 many of species which were not contained in his collection were 

 loaned to him for study by Professor Bruner and still others were 

 sent to him for examination by the United States National Museum. 

 Others furnished material for this revision, but in such small quanti- 

 ties that the paper may be said to be based almost wholly upon the 

 material in the three mentioned collections. A very fair idea of the 

 relative importance of these collections in the present work may be 

 had from the number of lectotypes chosen from each of the collections 

 in the present paper. Of these types there are fifty-seven in the 

 Collection of the Museum of Comparative Zoology (all but three 

 being from the Scudder Collection), thirty-eight in the Hebard 

 Collection, ex Bruner, nineteen in the United States National Mu- 

 seum, one in the McNeill Collection, one in the University of Kansas 

 Collection, and one in the Brunner von Wattenwyl Collection. 



The choice of the types in the paper under consideration has been 

 greatly facilitated by the fact that in almost every case one of the 

 best and most suitable specimens in the typical series is figured, the
