This distinctive species shows a slight amount of simihirity to 

 the North American C. spartinae in the general form of the male 

 cercus; the ovipositor is decidedly longer than in any other 

 American species excepting C. stn'ctus and C. leptopterus, all of 

 which species differing greatly in most important respects. 



Caudell unfortunatel}' included males before him with a series 

 of brachypterous C. saUato7-, recording them as meridionale, a 

 synonym of saltator. We consequently here select and describe 

 the allotype.

Description nj Allotype. — Very siiniiar to type excepting in sex characters. 

 Size medium, form very slender. Head with vertex strongly produced, when 

 seen from lateral aspect not ascending above plane of occiput; fastigium of 

 vertex narrow, greatest width verj- slightly more than one-half that of pro.xi- 

 mal antennal joint, narrowing strongly to point two-thirds of the ilistance 

 from apex to facial suture, thence subparallel to latter, two and one-half times 

 as long as broad. Eyes rather small for the South American species of the 

 genus (about as in C. brevipennis and C. spartinae) and also not strongly pro- 

 truding. Lateral lobes of pronotum with cephalic margin very broadly and 

 evenly convex and unusually oblique to the rather sharply rounded ventro- 

 caudal angle which is rectangulate, caudal margin ahiiost straight but with a 

 subobsolete convexity at convex callositj^ humeral sinus absent, convex callosity 

 moderately broad. Tegmina rather narrow, reaching two-thirds of the dis- 

 tance to the apex of abdomen with apices truncate and broadly rounded, veins 

 distinct but very delicate, veinlets exceedingly delicate, tympanum very small 

 and distinctly longitudinal (slightly more so than in C. versicolor), with stridu- 

 lating vein decidedly swollen for two-thirds of its length; wings about four- 

 fifths as long as tegmina with broadly rounded apices showing a tendency 

 toward an aborted condition. Cerci rather slender and elongate, brief prox- 

 imal portion rather stout, very elongate mesal portion decidedly and evenl\- 

 swollen except above the proximo-ventral rather slender tooth, which it over- 

 hangs in a squared projection with immediate angle rounded, the tooth
