REHX AND HEBARD 267 



callosity moderately broad.'''-* Tegmina elongate, slender, nar- 

 rowing evenly to the rather sharply- rounded apex, male tympa- 

 num much as in saltcttor. The species is apparently normally 

 macropterous, only occasional specimens being semi-macropterous 

 over the greater portion of its range, but the type series demon- 

 strates that in Ecuador a semi-macropterous condition is often 

 found. Male cerci similar to those of saltator but not as elon- 

 gate, the enlarged portion very slightly overhangs the base of 

 the tooth and the margins of the distal portion are slightly con- 

 vergent, thus making the apex rather sharply roun(l(>d. Sub- 

 genital plate with distal margin weakly convex between the rather 

 long disto-lateral styles. Caudal femora much as in saltator, 

 but with both ventro-external and ventro-internal margins 

 armed; genicular lobes normally bispinose; genicular areas 

 apically darkened; the ventro-external margins are armed in the 

 thirty-one perfect specimens before us as follows: 

 Number of spines, 12 2-3 2-4 3-3 3-4 4-4 



Number of specimens, 1 12 19 7 



Number of spines, 4-5 4-6 5-3 5-5 5-6 



Number of specimens, 6 1111 



The ventro-internal margins of the caudal femora are also 

 armed, as follows: 



Number of spines, 0-1 0-2 1-1 1-2 1-3 2-2 



Number of specimens, 9 1 7 111 2 



The ovipositor is short, slender and usually almost straight.

"3 In the original description, Giglio-Tos states that the convex callosity is 

 narrow; it is narrow, but when (-ompared ^"ith the other American species we 

 can but describe it as we have done above. The shades of meaning for such 

 characters are very difficult to express and uniformity is difficult to maintain 

 even in one and the same paper.
