Head with eyes but little wider than pronotum, triangfular the

 sloping, on same plane as pronotum, the surface irregular, a deep 

 median furrow, narrow on posterior half and not quite reaching the

 inate margin at the apex. Front gibbous, forming a right angle 

 with vertex, clypeus obtusely angled. Fronotum sexangular, round- 

 ing in front, the submargin depressed with a few deep pits, disc con-

 scarcely half the size of this species. It belong to the 

 genus^ Tettigouia and has not yet been found north of cen- 

 tral Mexico.
