and scutellnm togetlier, transverse, the former truncated at the base, 

 anteriorly obtusely angulated, the latter about twice longer than the 

 thorax : tegmina slightly narrowed behind the middle, at the apex very 

 obtusely rounded ; corium a little longer than the clavus ; radial vein of 

 tegmina forked at the base, ulnar veins forked in the middle or a little 

 before the middle : wings very broad, deeply emarginate at the apex : 

 last tibias bispinose : first joint of last tarsi rather short. Head and thorax 

 equally broad, the former not prominulous before the eyes, vertex trans- 

 verse, subequal in breadth to the eyes ; frons equally long and broad, 

 amplified near the apex : sides of clypeus furnished with a ridge : body a 

 little compressed (8tdl). Type, T. fusca, Stal.

<J . Fuscous, subcompressed, feet pallescent : corium and clavus 

 obsoletely sprinkled pale on the disc : vertex twice broader than long : 

 frons nearly equally long and towards the apex broad, furnished with a 

 single, distinct, obtuse ridge running through it, continued through the 

 clypeus : tegmina somewhat broadish, gradually a little amplified from 

 the base scarcely to the middle, thence distinctly narrowed (Stal),

Luteous spotted with black : head transverse, anteriorly trispinose, 

 one obtuse point in front of each eye and one forming a prolongation of 

 the frons : tegmina anteriorly dilated, luteous or ochraceous-yellow, with 

 some small tubercles and short transverse streaks, black ; wings brunne- 

 ous : body beneath yellow, variegated with black ; feet flavescent. The 

 anterior margin of the tegmina is spinose ; it comprises a limbus outside 

 the radius as broad as the external flap of the wing, about half a line, 

 transparent, vitriform, or like an exceedingly fine plate of talc, furnished 

 throughout with oblique veins (parallel to each other) contrasting in 

 colour and substance with that of the limbus itself. These veins when 

 the limbus is injured stand out like the teeth of a comb and give a pecu- 

 liar appearance to the insect. The frons is ascending and is divided from 

 the base to the upper margin into three facettes which form between them 

 obtuse angles ; the median increases from below upwards and reaches the 

 vertex and is divided by a longitudinal ridge which descends from above
