Length 20-22 mm. 



Head with crown well-produced, median length considerably less 

 than transocular widdi, apex elevated and carinate; ocelli located on a 

 line between anterior angles of eyes, each equidistant from adjacent 

 eye angle and midline of crown ; with a median full-length fovea which 

 is much broader apically than at base, without an M -shaped elevation 

 bordering posterior margin, with a longitudinal carina laterad of each 

 ocellus; lateral clypeal sutures extending onto crown; antennal ledges 

 protuberant, with a narrow longitudinal fovea, in lateral aspect not 

 carinate dorsally, abrupdy declivous anteriorly; face with clypeus 

 concave, muscle impressions prominent, transclypeal sulcus not entire, 

 pubescent below; clypellus produced and angular in lateral aspect, 

 carinate medially. 



Thorax with pronotum much wider than head, lateral margins 

 convergent anteriorly, coarsely rugose to punctate, inconspicuously 

 pubescent, with a pair of very conspicuous conical dorsal discal pro- 

 tuberances extending dorsally and laterally, posterior margin concave, 

 with rectilinear dorsopleural carinae, scutellum transversely striate in 

 posterior half. Forewings without a membrane, veins elevated and 

 distinct, claval veins parallel, veins of corium forming a plexus apically, 

 with supernumerary anteapical crossveins to costal margin; wing apices
