 nounced in the female than in the male, retrorse, apex rather blunt; 

 interspace between the mesosternal lobes strongly longitudinal in 

 both sexes, that between the mesosternal lobes as broad as long and 

 contracted caudad in the male, slightly transverse in the female. 

 Supra-anal plate of the male acute-angulate, the margins slightly 

 constricted halfway to the apex, a deeply impressed area like the 

 inverted upper portion of an (exclamation mark present proximo-

 somewhat rostrate, strongly keeled dorsad, distinctly so ventrad, and 

 narrowly rounded acute angulate when seen from the side, the sides 

 of the body of the plate provided with a longitudinal cariniform fold 

 extending two-thirds the length of the plate. Ovipositor jaws of the 

 female robust, blunt, the margins of the dorsal pair not serrate. 

 Cephalic and median limbs rather robust, the 

 femora distinctly inflated in the male. Caudal 

 femora about two-thirds the length of the tegmina, 

 .rather slender, tapering, carinas unarmed except 

 for a slight serrulation on the dorsal carina of 

 the male, pagina with a moderately regular but 

 poorly impressed pattern, genicular lobes strongly 

 rounded; caudal tibine slightly shorter than the
