broader tegmina with apices truncate and very broadly rounded 

 (very much more so than in any examples of saltator), with veins 

 decidedly less cUstinct and by the much more decidedly curved 

 ovipositor. The males are said to have the distinguishing char- 

 acters of the tegmina equally pronounced. We find the wings 

 of the females to be distinctly aborted, but not reduced to a 

 filiform condition. We do not consider the incision of tiie female 

 subgenital plate given by Giglio-Tos to be of any value. 



In addition to the characters given above, we would say that 

 in the specimens before us the form is distinctly heavier than 

 even the extreme of this tendency found in saltator in Paraguay'. 

 The eyes are distinctly larger and more protruding, while the 

 vertex is narrower than is normal in saltator, being slightly less 

 than two-thirds the width of the proximal antennal joint, and 

 decidedly deeper, being two and three-fourths times as deep as 

 greatest width, with sides distinctly but weakly convergent, 

 almost straight. The lateral lobes of the pronotum have the 

 cephalic margin broadly rounded to the ventro-caudal angle with 

 the ventro-cephalic angle weakly indicated, the ventro-caudal 

 angle is sharply rounded, the caudal margin straight with the 

 humeral sinus absent, the convex callosity is very narrow. The 

 latero-dorsal pale bands of the abdomen are slightly more dis- 

 tinct than in any specimens of saltator before us, while the gen- 

 icular areas are contrastingly darkened. The ovipositor is not 

 only more decidedly curved than in that species but differs also 

 in shape, narrowing appreciabh' from the median point to the 

 acute apex, which narrowing begins in saltator near the apex as 

 is normal for the great majority of the American species. The 

 specimens before us have the ventro-external margins of the 

 caudal femora armed with 4 and 5 and 5 and 5 spines, which are 

 heavier than normal in the allied species. Their measurenumts 

 are: length of body 15.5-16.3, pronotum 3.7-4, tegmen 3 3.9, 

 caudal femur 15.4-16, ovipositor 9.7-10.1 and width of tc^gmen 

 2.6-2.7 mm. 



Specimeiis Examined: 2; 2 females.
