Allied to T. agrestis McNeill, but differing in the longer wings and 

 tegmina, the weaker lateral fastigial carina and the darker coloration. 



Size rather large. Head with the interspace between the eyes 

 moderately broad; scutellum of the vertex slightly longer than broad, 

 but slightly excavated and without a median carina; lateral foveolse 

 minute, subtrigonal; frontal costa not reaching the clypeus, faintly 

 expanded inferiorly, superior portion subequal, all moderately sulcate ; 

 eye moderately prominent, rather small, decidedly less than the infra- 

 ocular portion of the gense in length; antennae slight. Pronotum with 

 the disk flat, median carina distinctly carinate anteriorly, but very 

 weak posteriorly; prozona about half the length of the metazona; 

 anterior margin very obtuse-angulate, posterior margin acute-angulate ; 

 lateral lobes of the pronotum subequal in width, the inferior margin 

 posteriorly with a small angulate process. Interval between the meta- 

 sternal lobes shallow and strongly transverse. Tegmina long, over 

 five times as long as the greatest width; apex obliquely truncate. 

 Wings slender, considerably more than half again as long as wide; 

 apex somewhat falcate. Posterior femora robust, the inferior margin 

 distinctly more arcuate than the superior. 



General color ecru-drab, suffused more or less strongly with russet. 

 Head and pronotum strongly infuscate and punctulate with russet. 

 Tegmina with two transverse bars poorly represented by groups of 

 russet annuli and small maculations, these almost limited to the dis-
