median carina, viewed in profile angulate produced forward before 
the eyes (in the type species a distance scarcely equal to two-thirds 
the length of one of the eyes). Pronotum anteriorly truncate, 
advanced forward coming in contact with the eyes ; lateral lobes 
having the posterior angles slightly re flexed outwards, obtuse and 
obliquely truncate behind. The superior elytral sinus of lateral 
lobes, the elytra and wings absent. 
This genus is represented by one diminutive apterous species, 
the type being Spadotettix fletcheri described herewith.

Body small, apterous, coloured dark testaceous infuscated. Head 
not exserted, vertex viewed from above oblong, wider than one of 
the eyes, widened backwards between them and strongly produced 
forward beyond them a distance of about half their length ; the 
crown bearing a distinct median carina, which projects forward as 
a prominent tooth from the middle of the rounded-truncate border ; 
on either side of median carina longitudinally canaliculate ; the 
anterior marginal carinulse flexed backward laterally running 
parallel to the front border of the eyes ; in profile view the vertex 
strongly acute angulate produced a distance nearly equal to two- 
thirds the length of one of the eyes ; face distinctly oblique, the 
facial frontal costa slightly excavate opposite the eyes, the rami 
somewhat widely sulcate, and barely compresso-elevated between 
the antennae ; eyes moderately small; posterior ocelli situated in 
advance of the middle of the eyes; antennae slender and filiform, 
consisting of thirteen to fourteen articles, inserted opposite the 
anterior lower angle of the eyes. Pronotum granulate subscabrous, 
moderately widened between the shoulders ; dorsum subtectiform 
forward depressed subfossulate behind the shoulders ; median carina 
biundulate, distinctly compresso-elevated in front of the shoulders ; 
humeral angles widely obtuse angulate and carinate; the front 
border truncate advanced to the eyes, posteriorly cuneiform and
