396 NEW NORTH AMERICAN MELANOPLI (ORTHOPTERA) 



though showing more strongly the v. eurycercus type. In this individual 

 the length of these appendages is two and one-third times the basal width, 

 the lateral margins showing weak convergence in the distal two-thirds to 

 the rather broadly rounded distal portion, with apex meso-ventrad. The 

 greatest cereal abbreviation is found in the two males from Sounding Knob, 

 Virginia, in which the length of these appendages is but one and one-third 

 times the basal width. 



The apical tuberculation of the subgenital plate in males varies in degree 

 of development, though usually prominent and sharply rounded. Rarely 

 it is divided, giving to the subgenital plate of such individuals a bitubercu- 

 late appearance. 



In coloration full agreement with typical viridipes is shown, except that 

 the caudal femora exhibit an average more intensive pattern. The two 

 transverse bars are heavier, running from their origin in the dorsal portion 

 of the internal surface across the dorsal surface and obliquely across the ex- 

 ternal surface, there fusing at the lower margin of the pagina. 32 This is not 

 a constant feature, some series showing a distinctly more intensive pattern 

 than others. The Marion County, Indiana series shows extreme recession, 

 the caudal femoral markings being subobsolete in some males and the major- 

 ity of females. The specimens from Cincinnati, Ohio; White Sulphur Springs, 

 West Virginia, and Sounding Knob, Virginia show the maximum of color 

 intensification.
