HO. 1124. REVISION OF THE MELANOPLI SC UDDER. 407 



EXPLANATION OF PLATES. 



With the exception of a few figures specially noted below, all the drawings for 

 these plates were made by Mr. J. Henry Blake, of Cambridge, Massachusetts, and 

 the expense met by a special grant for the purpose from the ELIZABETH THOMPSON 

 SCIENCE FUND, which is here gratefully acknowledged. 



Unless otherwise stated (under the names of individuals or institutions placed in 

 parentheses), all the drawings of American species were made from specimens in my 

 own collection. Plate I illustrates the venation of the tegmina in a few species, and 

 the figures are here magnified five diameters. The remaining plates show the abdom- 

 inal appendages of the males of all but two or three of the species, and these are 



magnified four diameters.
