THE NEW ENGLAND MELANOPLI. 



BY SAMUEL II. SCUDDER, CAMniiinGE, MASS. 



Some ve.irs ago (Proc. Bost. soc nat. 

 hist., xix, 2S1-2S6, 1S7S) I published 

 a table for the determination of the 

 New England species of Melanophis, 

 of which I enumerated six species. 

 Several errors are to be found in the 

 table, leading to niucli confusion, and I 

 therefore ofler heie another, more in 

 harmony witli a revision of all the 

 Melanopli of North America I shall 

 shortly publish with illustrations. At 

 the same time the other species of the 

 group Melanopli. embracing all our 

 New Englautl Aciididae excepting 

 Schistocerca, are added, including some 

 species not then known to inhabit New 

 England. Most of the additional species 

 are due to the industrious and discrim- 

 inating collections of Mr. A. P. Morse, 

 in whose Preliminary List of the Acri- 



didae of New England (Psyche, vii, 

 102-10S) all the thirteen species here 

 enumerated will be founti but sometimes 

 under diHerent names, my revision 

 showing the necessity of several altera- 

 tions. As the reasons for the clianges 

 will appear in my forthcoming paper. I 

 will merely add here a list of the changes 

 by reference to Morse's List.
